This patch contains the following changes: * access cfg via aq_nic_get_cfg() in aq_nic_start() and aq_nic_map_skb(); * call aq_nic_get_dev() just once in aq_nic_map_skb(); * move ring allocation/deallocation out of aq_vec_alloc()/aq_vec_free(); * add the missing aq_nic_deinit() in atl_resume_common(); * rename 'tcs' field to 'tcs_max' in aq_hw_caps_s to differentiate it from the 'tcs' field in aq_nic_cfg_s, which is used for the current number of TCs; * update _TC_MAX defines to the actual number of supported TCs; * move tx_tc_mode register defines slightly higher (just to keep the order of definitions); * separate variables for TX/RX buff_size in hw_atl*_hw_qos_set(); * use AQ_HW_*_TC instead of hardcoded magic numbers; * actually use the 'ret' value in aq_mdo_add_secy(); Signed-off-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2020-05-21 This series contains updates to ice driver only. Several of the changes are fixes, which could be backported to stable, of which, only one was marked for stable because of the memory leak potential. Jake exposes the information in the flash memory used for link management, which is called the netlist module. Henry and Tony add support for tunnel offloads. Brett adds promiscuous support in VF's which is based on VF trust and the new vf-true-promisc flag. Avinash fixes an issue where a transmit timeout for a queue that belongs to a PFC enabled TC is not a true transmit timeout, but because the PFC is in action. Dave fixes the check for contiguous TCs to allow for various UP2TC mapping configurations. Also fixed an issue when changing the pause parameters would could multiple link drop/down's in succession, which in turn caused the firmware to not generate a link interrupt for the driver to respond to. Anirudh (Ani) fixed a potential race condition in probe/open due to a bit being cleared too early. Lihong updates an error message to make it more meaningful instead of just printing out the numerical value of the status/error code. Also fixed an incorrect return value if deleting a filter does not find a match to delete or when adding a filter that already exists. Karol fixes casting issues and precision loss in the driver. Jesse make the sign usage more consistent in the driver by making sure all instances of vf_id are unsigned, since it can never be negative. Eric fixes a potential memory leak in ice_add_prof_id_vsig() where was not cleaning up resources properly when an error occurs. Michal to help organize the filtering code in the driver, refactor the code into a separate file and add functions to prepare the filter information. Bruce cleaned up a conditional statement that always resulted in true and provided a comment to make it more obvious. Also cleaned up redundant code checks. Tony helps with potential namespace issues by renaming a 'ice' specific function with the driver name prepended. ==================== Signed-off-by: -

Roopa Prabhu says: ==================== Support for fdb ECMP nexthop groups This series introduces ecmp nexthops and nexthop groups for mac fdb entries. In subsequent patches this is used by the vxlan driver fdb entries. The use case is E-VPN multihoming [1,2,3] which requires bridged vxlan traffic to be load balanced to remote switches (vteps) belonging to the same multi-homed ethernet segment (This is analogous to a multi-homed LAG but over vxlan). Changes include new nexthop flag NHA_FDB for nexthops referenced by fdb entries. These nexthops only have ip. The patches make sure that routes dont reference such nexthops. example: $ip nexthop add id 12 via 172.16.1.2 fdb $ip nexthop add id 13 via 172.16.1.3 fdb $ip nexthop add id 102 group 12/13 fdb $bridge fdb add 02:02:00:00:00:13 dev vxlan1000 nhid 101 self [1] E-VPN https://tools.ietf.org/html/rfc7432 [2] E-VPN VxLAN: https://tools.ietf.org/html/rfc8365 [3] LPC talk with mention of nexthop groups for L2 ecmp http://vger.kernel.org/lpc_net2018_talks/scaling_bridge_fdb_database_slidesV3.pdf v4 - - fix error path free_skb in vxlan_xmit_nh - fix atomic notifier initialization issue (Reported-by: kernel test robot <rong.a.chen@intel.com>) The reported error was easy to locate and fix, but i was not able to re-test with the robot reproducer script due to some other issues with running the script on my test system. v3 - fix wording in selftest print as pointed out by davidA v2 - - dropped nikolays fixes for nexthop multipath null pointer deref (he will send those separately) - added negative tests for route add with fdb nexthop + a few more - Fixes for a few fdb replace conditions found during more testing - Moved to rcu_dereference_rtnl in vxlan_fdb_info and consolidate rcu dereferences - Fixes to build failures Reported-by: kbuild test robot <lkp@intel.com> - DavidA, I am going to send a separate patch for the neighbor code validation for NDA_NH_ID if thats ok. ==================== Signed-off-by:

Todays vxlan mac fdb entries can point to multiple remote ips (rdsts) with the sole purpose of replicating broadcast-multicast and unknown unicast packets to those remote ips. E-VPN multihoming [1,2,3] requires bridged vxlan traffic to be load balanced to remote switches (vteps) belonging to the same multi-homed ethernet segment (E-VPN multihoming is analogous to multi-homed LAG implementations, but with the inter-switch peerlink replaced with a vxlan tunnel). In other words it needs support for mac ecmp. Furthermore, for faster convergence, E-VPN multihoming needs the ability to update fdb ecmp nexthops independent of the fdb entries. New route nexthop API is perfect for this usecase. This patch extends the vxlan fdb code to take a nexthop id pointing to an ecmp nexthop group. Changes include: - New NDA_NH_ID attribute for fdbs - Use the newly added fdb nexthop groups - makes vxlan rdsts and nexthop handling code mutually exclusive - since this is a new use-case and the requirement is for ecmp nexthop groups, the fdb add and update path checks that the nexthop is really an ecmp nexthop group. This check can be relaxed in the future, if we want to introduce replication fdb nexthop groups and allow its use in lieu of current rdst lists. - fdb update requests with nexthop id's only allowed for existing fdb's that have nexthop id's - learning will not override an existing fdb entry with nexthop group - I have wrapped the switchdev offload code around the presence of rdst [1] E-VPN RFC https://tools.ietf.org/html/rfc7432 [2] E-VPN with vxlan https://tools.ietf.org/html/rfc8365 [3] http://vger.kernel.org/lpc_net2018_talks/scaling_bridge_fdb_database_slidesV3.pdf Includes a null check fix in vxlan_xmit from Nikolay v2 - Fixed build issue: Reported-by:

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2020-05-21 This series contains updates to igc and e1000. Andre cleans up code that was left over from the igb driver that handled MAC address filters based on the source address, which is not currently supported. Simplifies the MAC address filtering code and prepare the igc driver for future source address support. Updated the MAC address filter internal APIs to support filters based on source address. Added support for Network Flow Classification (NFC) rules based on source MAC address. Cleaned up the 'cookie' field which is not used anywhere in the code and cleaned up a wrapper function that was not needed. Simplified the filtering code for readability and aligned the ethtool functions, so that function names were consistent. Alex provides a fix for e1000 to resolve a deadlock issue when NAPI is being disabled. Sasha does additional cleanup of the igc driver of dead code that is not used or needed. v2: Fix the function header comment in patch 3 of the series, based on the feedback from Jakub Kicinski. ==================== Reviewed-by:Jakub Kicinski <kuba@kernel.org> Signed-off-by:

Change min() macros to min_t() which has compare type specified and it helps avoid precision loss. In some cases there was precision loss during calls or assignments. Some fields in structs were unnecessarily large and gave multiple warnings. There were also some minor type differences which are now fixed as well as some cases where a simple cast was needed. Callers were were passing data that is a u16 to ice_sched_cfg_node_bw_alloc() but the function was truncating that to a u8. Fix that by changing the function to take a u16. Signed-off-by:

As soon as the driver registers the PF netdev, userspace utilities like NetworkManager try to bring up the associated interface. When this happens, the driver may not have finished initializing fully, resulting in a bunch of errors in the interface up flow. The driver already has a mechanism to indicate if it's not up yet; by setting the __ICE_DOWN bit in pf->state, but this bit gets cleared too early in the current flow. So clear this bit only when the driver is fully up. Also check for the same bit in the ice_open flow, and return -EBUSY if the bit is set. Also in ice_open, replace references of vsi->back with a local variable. Signed-off-by:

Currently, the ice driver is setting a PHY configuration, which causes a link drop, and then additionally it calls for a nway_reset, which restarts auto-negotiation on the link, which also causes a link drop. These two link events in such close timing is causing the FW to not be able to generate a link interrupt for the driver to respond to. Remove the unnecessary auto-negotiation restart from the set pauseparams flow. Also remove error path that would have performed an ice_down/ice_up as that is also unnecessary. Signed-off-by:

When there's a Tx timeout for a queue which belongs to a PFC enabled TC, then it's not because the queue is hung but because PFC is in action. In PFC, peer sends a pause frame for a specified period of time when its buffer threshold is exceeded (due to congestion). Netdev on the other hand checks if ACK is received within a specified time for a TX packet, if not, it'll invoke the tx_timeout routine. Signed-off-by:

Implement promiscuous support for VF VSIs. Behaviour of promiscuous support is based on VF trust as well as the, introduced, vf-true-promisc flag. A trusted VF with vf-true-promisc disabled will be the default VSI, which means that all traffic without a matching destination MAC address in the device's internal switch will be forwarded to this VF VSI. A trusted VF with vf-true-promisc enabled will go into "true promiscuous mode". This amounts to the VF receiving all ingress and egress traffic that hits the device's internal switch. An untrusted VF will only receive traffic destined for that VF. The vf-true-promisc-support flag cannot be toggled while any VF is in promiscuous mode. This flag should be set prior to loading the iavf driver or spawning VF(s). Signed-off-by:

Every time we access the 'etype' and 'vlan_tci' fields from struct igc_nfc_filter to enable or disable filters in hardware we have to convert them from big endian to host order so it makes more sense to simply have these fields in host order. The byte order conversion should take place in igc_ethtool_get_nfc_ rule() and igc_ethtool_add_nfc_rule(), which are called by .get_rxnfc and .set_rxnfc ethtool ops, since ethtool subsystem is the one who deals with them in big endian order.

The Network Flow Classification (NFC) support code from IGC driver uses terms such as 'rule', 'filter', 'entry', 'input' interchangeably when referring to NFC rules, making it harder to follow the code. This patch renames IGC's internal APIs, structs, and variables so we stick with the term 'rule' since this is the term used in ethtool APIs.
