      ice: Add support for VLAN priority filters in switchdev · 34800178
      Martyna Szapar-Mudlaw authored
      Enable support for adding TC rules that filter on the VLAN priority
      in switchdev mode.
      
      VLAN priority are the first 3 bits of 16b switch field vector word
      which contain also vlan id value within its last 12 bits.
      When getting vlan priority value from tc match.key it
      has to be shifted first to proper bits positions (by VLAN_PRIO_SHIFT)
      and then can be added to the joint 'vlan' field in ice_vlan_hdr
      in lookup element.
      
      The mask of lookup changes accordingly.
      0x0FFF - when only vlan id is added in filter
      0xE000 - when only vlan priority is added in filter
      0xEFFF - when both these values are specified

      netfilter fix for net-next
      
      This is a late bug fix for the *net-next* tree to make nftables
      "fib" expression play nice with VRF devices.
      
      This was broken since day 1 (v4.10) so I don't see a compelling reason

      Add special treatment of VRF devices so that typical reverse path

      ====================
      sfc: bare bones TC offload
      
      This series begins the work of supporting TC flower offload on EF100 NICs.
      This is the absolute minimum viable TC implementation to get traffic to
       VFs and allow them to be tested; it supports no match fields besides
       ingress port, no actions besides mirred and drop, and no stats.
      More matches, actions, and counters will be added in subsequent patches.
      
      Changed in v2:
       - Add missing 'static' on declarations (kernel test robot, sparse)

          tc filter add dev $VFREP parent ffff: flower skip_sw \
              action mirred egress redirect dev $PF
       gives a VF unfiltered access to the network out the physical port ($PF
       acts here as a physical port representor).
      More matches, actions, and counters will be added in subsequent patches.

      sfc: optional logging of TC offload errors · 7c9d266d
      Edward Cree authored
      TC offload support will involve complex limitations on what matches and
       actions a rule can do, in some cases potentially depending on rules
       already offloaded.  So add an ethtool private flag "log-tc-errors" which
       controls reporting the reasons for un-offloadable TC rules at NETIF_INFO.

      net: ethernet: rmnet: Replace zero-length array with DECLARE_FLEX_ARRAY() helper · c87e4ad1
      Gustavo A. R. Silva authored
      Zero-length arrays are deprecated and we are moving towards adopting
      C99 flexible-array members, instead. So, replace zero-length arrays
      declarations in anonymous union with the new DECLARE_FLEX_ARRAY()
      helper macro.
      
      This helper allows for flexible-array members in unions.

      composite flexible array structs (as detailed in the coming memcpy()
      hardening series[1]), split the memcpy() of the header and the payload
      so no false positive run-time overflow warning will be generated.

      Merge branch 'net-ipa-generalized-register-definitions' · e1d07700
      Jakub Kicinski authored
      Alex Elder says:
      
      ====================
      net: ipa: generalized register definitions
      
      This series is quite a bit bigger than what I normally like to send,
      and I apologize for that.  I would like it to get incorporated in
      its entirety this week if possible, and splitting up the series
      carries a small risk that wouldn't happen.
      
      Each IPA register has a defined offset, and in most cases, a set
      of masks that define the width and position of fields within the
      register.  Most registers currently use the same offset for all
      versions of IPA.  Usually fields within registers are also the same
      across many versions.  Offsets and fields like this are defined
      using preprocessor constants.
      
      When a register has a different offset for different versions of
      IPA, an inline function is used to determine its offset.  And in
      places where a field differs between versions, an inline function is
      used to determine how a value is encoded within the field, depending
      on IPA version.
      
      Starting with IPA version 5.0, the number of IPA endpoints supported
      is greater than 32.  As a consequence, *many* IPA register offsets
      differ considerably from prior versions.  This increase in endpoints
      also requires a lot of field sizes and/or positions to change (such
      as those that contain an endpoint ID).
      
      Defining these things with constants is no longer simple, and rather
      than fill the code with one-off functions to define offsets and
      encode field values, this series puts in place a new way of defining
      IPA registers and their fields.  Note that this series creates this
      new scheme, but does not add IPA v5.0+ support.
      
      An enumerated type will now define a unique ID for each IPA register.
      Each defined register will have a structure that contains its offset
      and its name (a printable string).  Each version of IPA will have an
      array of these register structures, indexed by register ID.
      
      Some "parameterized" registers are duplicated (this is not new).
      For example, each endpoint has an INIT_HDR register, and the offset
      of a given endpoint's INIT_HDR register is dependent on the endpoint
      number (the parameter).  In such cases, the register's "stride" is
      defined as the distance between two of these registers.
      
      If a register contains fields, each field will have a unique ID
      that's used as an index into an array of field masks defined for the
      register.  The register structure also defines the number of entries
      in this field array.
      
      When a register is to be used in code, its register structure will
      be fetched using function ipa_reg().  Other functions are then used
      to determine the register's offset, or to encode a value into one of
      the register's fields, and so on.
      
      Each version of IPA defines the set of registers that are available,
      including all fields for these registers.  The array of defined
      registers is set up at probe time based on the IPA version, and it
      is associated with the main IPA structure.
      ====================
