      ====================
      net: ipa: start adding IPA v4.5 support
      
      This series starts updating the IPA code to support IPA hardware
      version 4.5.
      
      The first patch fixes a problem found while preparing these updates.
      Testing shows the code works with or without the change, and with
      the fix the code matches "downstream" Qualcomm code.
      
      The second patch updates the definitions for IPA register offsets
      and field masks to reflect the changes that come with IPA v4.5.  A
      few register updates have been deferred until later, because making
      use of them involves some nontrivial code updates.
      
      One type of change that IPA v4.5 brings is expanding the range of
      certain configuration values.  High-order bits are added in a few
      cases, and the third patch implements the code changes necessary to
      use those newly available bits.
      
      The fourth patch implements several fairly minor changes to the code
      required for IPA v4.5 support.
      
      The last two patches implement changes to the GSI registers used for
      IPA.  Almost none of the registers change, but the range of memory
      in which most of the GSI registers is located is shifted by a fixed
      amount.  The fifth patch updates the GSI register definitions, and
      the last patch implements the memory shift for IPA v4.5.

      net: ipa: adjust GSI register addresses · cdeee49f
      Alex Elder authored
      The offsets for almost all GSI registers we use have different
      offsets starting at IPA version 4.5.  Only two registers remain
      in their original location.
      
      In a way though, the new register locations are not *that*
      different.  The entire group of affected registers has simply
      been shifted down in memory by a fixed amount (0xd000).  So for
      example, the channel context 0 register that has a base offset of
      0x0001c000 for "older" hardware now has a base offset of 0x0000f000.
      
      This patch aims to add support for IPA v4.5 registers at their new
      offets in a way that minimizes the amount of code that needs to
      change.  It is not ideal, but it avoids the need to maintain
      a nearly complete set of additional register offset definitions.
      
      The approach takes advantage of the fact that when accessing GSI
      registers we do not access any of memory at lower end of the "gsi"
      memory range (with two exceptions already noted).  In particular,
      we do not access anything within the bottom 0xd000 bytes of the
      GSI memory range.
      
      For IPA version 4.5, after we map the GSI memory, we adjust the
      virtual memory pointer downward by the fixed amount (0xd000).
      That way, register accesses using the offsets defined by the
      existing GSI_REG_*() macros will resolve to the proper locations
      for IPA version 4.5.
      
      The two registers *not* affected by this offset are accessed only
      in gsi_irq_setup().  There, for IPA version 4.5, we undo the general
      register adjustment by adding the fixed amount back to the virtual
      address to access these registers.

      net: ipa: add support to code for IPA v4.5 · 8bfc4e21
      Alex Elder authored
      Update the IPA code to make use of the updated IPA v4.5 register
      definitions.  Generally what this patch does is, if IPA v4.5
      hardware is in use:
        - Ensure new registers or fields in IPA v4.5 are updated where
          required
        - Ensure registers or fields not supported in IPA v4.5 are not
          examined when read, or are set to 0 when written
      It does this while preserving the existing functionality for IPA
      versions lower than v4.5.
      
      The values to program for QSB_MAX_READS and QSB_MAX_WRITES and the
      source and destination resource counts are updated to be correct for
      all versions through v4.5 as well.
      
      Note that IPA_RESOURCE_GROUP_SRC_MAX and IPA_RESOURCE_GROUP_DST_MAX
      already reflect that 5 is an acceptable number of resources (which
      IPA v4.5 implements).

      net: ipa: add new most-significant bits to registers · 1af15c2a
      Alex Elder authored
      IPA v4.5 adds a few fields to the endpoint header and extended
      header configuration registers that represent new high-order bits
      for certain offsets and sizes.  Add code to incorporate these upper
      bits into the registers for IPA v4.5.
      
      This includes creating ipa_header_size_encoded(), which handles
      encoding the metadata offset field for use in the ENDP_INIT_HDR
      register in a way appropriate for the hardware version.  This and
      ipa_metadata_offset_encoded() ensure the mask argument passed to
      u32_encode_bits() is constant.

      net: ipa: update IPA registers for IPA v4.5 · 5b6cd69e
      Alex Elder authored
      Update "ipa_reg.h" so that register definitions support IPA hardware
      version 4.5, in addition to versions 3.5.1 through v4.2.  Most of
      the register definitions are the same, but in some cases fields are
      added, changed, or eliminated.
      
      Updates for a few IPA v4.5 registers are more complex, and adding
      those definition will be deferred to separate patches.  This patch
      only updates the register offset and field definitions, and adds
      informational comments.
      
      The only code change avoids accessing the backward compatibility
      register for IPA version 4.5 in ipa_hardware_config().  Other IPA
      v4.5-specific code changes will come later.

      Starting with IPA v4.2 there is a GSI channel option to use an
      "escape buffer" instead of prefetch buffers.  This should be used
      for all channels *except* the AP command TX channel.  The logic

      tipc: make node number calculation reproducible · 5f75e0a0
      Jon Maloy authored
      The 32-bit node number, aka node hash or node address, is calculated
      based on the 128-bit node identity when it is not set explicitly by
      the user. In future commits we will need to perform this hash operation
      on peer nodes while feeling safe that we obtain the same result.
      
      We do this by interpreting the initial hash as a network byte order
      number. Whenever we need to use the number locally on a node
      we must therefore translate it to host byte order to obtain an
      architecure independent result.
      
      Furthermore, given the context where we use this number, we must not
      allow it to be zero unless the node identity also is zero. Hence, in
      the rare cases when the xor-ed hash value may end up as zero we replace
      it with a fix number, knowing that the code anyway is capable of
      handling hash collisions.

      2. Call lapb_disconnect_request() on NETDEV_GOING_DOWN events to signal
         the peer that the connection will go down.
         (Only when the carrier is up.)
      
      3. When a NETDEV_DOWN event occur, clear all queues, enter state
         LAPB_STATE_0 and stop all timers.
      
      4. The NETDEV_CHANGE event makes it possible to handle carrier loss and
         detection.
      
         In case of Carrier Loss, clear all queues, enter state LAPB_STATE_0
         and stop all timers.
      
         In case of Carrier Detection, we start timer t1 on a DCE interface,
         and on a DTE interface we change to state LAPB_STATE_1 and start
         sending SABM(E).

         This change is needed so that the x25_neigh struct for an interface
         is already created when it shows up and is kept independently if the
         interface goes UP or DOWN.
      
         This is used in an upcomming commit, where x25 params of an neighbour
         will get configurable through ioctls.
      
      2. NETDEV_CHANGE event makes it possible to handle carrier loss and
         detection. If carrier is lost, clean up everything related to this
         neighbour by calling x25_link_terminated().
      
      3. Also call x25_link_terminated() for NETDEV_DOWN events and remove the
         call to x25_clear_forward_by_dev() in x25_route_device_down(), as
         this is already called by x25_kill_by_neigh() which gets called by
         x25_link_terminated().
      
      4. Do nothing for NETDEV_UP and NETDEV_GOING_DOWN events, as these will
         be handled in layer 2 (LAPB) and layer3 (X.25) will be informed by
         layer2 when layer2 link is established and layer3 link should be
         initiated.

      ====================
      mlxsw: Update adjacency index more efficiently
      
      The device supports an operation that allows the driver to issue one
      request to update the adjacency index for all the routes in a given
      virtual router (VR) from old index and size to new ones. This is useful
      in case the configuration of a certain nexthop group is updated and its
      adjacency index changes.
      
      Currently, the driver does not use this operation in an efficient
      manner. It iterates over all the routes using the nexthop group and
      issues an update request for the VR if it is not the same as the
      previous VR.
      
      Instead, this patch set tracks the VRs in which the nexthop group is
      used and issues one request for each VR.
      
      Example:
      
      8k IPv6 routes were added in an alternating manner to two VRFs. All the
      routes are using the same nexthop object ('nhid 1').
      
      Before:
      
       Performance counter stats for 'ip nexthop replace id 1 via 2001:db8:1::2 dev swp3':
      
                  16,385      devlink:devlink_hwmsg

             0.000000000 seconds user
             0.666923000 seconds sys
      
      Number of EMAD transactions corresponds to number of routes using the
      nexthop group.
      
      After:
      
       Performance counter stats for 'ip nexthop replace id 1 via 2001:db8:1::2 dev swp3':
      
                       3      devlink:devlink_hwmsg
      
             0.077655094 seconds time elapsed
      
             0.000000000 seconds user
             0.076698000 seconds sys
      
      Number of EMAD transactions corresponds to number of VRFs / VRs.
      
      Patch set overview:
      
      Patch #1 is a fix for a bug introduced in previous submission. Detected
      by Coverity.
      
      Patches #2 and #3 are preparations.
      
      Patch #4 tracks the VRs a nexthop group is member of.
      
      Patch #5 uses the membership tracking from the previous patch to issue
      one update request per each VR.

      in case the configuration of a certain nexthop group is updated and its
      adjacency index changes.
      
      Currently, the driver does not use this operation in an efficient
      manner. It iterates over all the routes using the nexthop group and
      issues an update request for the VR if it is not the same as the
      previous VR.
      
      Instead, use the VR tracking added in the previous patch to update the
      adjacency index once for each VR currently using the nexthop group.
      
      Example:
      
      8k IPv6 routes were added in an alternating manner to two VRFs. All the
      routes are using the same nexthop object ('nhid 1').
      
      Before:
      
      # perf stat -e devlink:devlink_hwmsg --filter='incoming==0' -- ip nexthop replace id 1 via 2001:db8:1::2 dev swp3
      
       Performance counter stats for 'ip nexthop replace id 1 via 2001:db8:1::2 dev swp3':
      
                  16,385      devlink:devlink_hwmsg
      
             4.255933213 seconds time elapsed
      
             0.000000000 seconds user
             0.666923000 seconds sys
      
      Number of EMAD transactions corresponds to number of routes using the
      nexthop group.
      
      After:
      
      # perf stat -e devlink:devlink_hwmsg --filter='incoming==0' -- ip nexthop replace id 1 via 2001:db8:1::2 dev swp3
      
       Performance counter stats for 'ip nexthop replace id 1 via 2001:db8:1::2 dev swp3':
      
                       3      devlink:devlink_hwmsg
      
             0.077655094 seconds time elapsed
      
             0.000000000 seconds user
             0.076698000 seconds sys
      
      Number of EMAD transactions corresponds to number of VRFs / VRs.

      Ido Schimmel authored
      For each nexthop group, track in which virtual routers (VRs) the group is
      used. This is going to be used by the next patch to perform a more
      efficient adjacency index update whenever the group's adjacency index
      changes.

      The send one refactor the hanle of xmit in act_mirred and prepare for the
      third one
      The last one add implict packet fragment support to fix the over mtu for

      This patch add support for a xmit hook to mirred, that gets executed before
      xmiting the packet. Then, when act_ct gets loaded, it configs that hook.
      The frag xmit hook maybe reused by other modules.
