* mlxsw: spectrum_switchdev: Do not leak RIFs when removing bridgeIdo Schimmel2018-08-263-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When a bridge device is removed, the VLANs are flushed from each configured port. This causes the ports to decrement the reference count on the associated FIDs (filtering identifier). If the reference count of a FID is 1 and it has a RIF (router interface), then this RIF is destroyed. However, if no port is member in the VLAN for which a RIF exists, then the RIF will continue to exist after the removal of the bridge. To reproduce: # ip link add name br0 type bridge vlan_filtering 1 # ip link set dev swp1 master br0 # ip link add link br0 name br0.10 type vlan id 10 # ip address add 192.0.2.0/24 dev br0.10 # ip link del dev br0 The RIF associated with br0.10 continues to exist. Fix this by iterating over all the bridge device uppers when it is destroyed and take care of destroying their RIFs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before MC-aware mode was enabled in commit 7b8195306694 ("mlxsw: spectrum: Configure MC-aware mode on mlxsw ports"), only 8 traffic classes were used. Under MC-aware regime, however, besides using TCs 0-7 for UC traffic, it additionally uses TCs 8-15 for BUM traffic. It is therefore desirable to show counters for these TCs as well. Update ethtool stats pool length, mlxsw_sp_port_get_strings() and mlxsw_sp_port_get_stats() to include artifacts for all 16 TCs. For consistency and simplicity, expose tc_no_buffer_discard_uc_tc for BUM TCs as well, even though it ought to stay at 0 all the time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function mlxsw_sp_port_get_sset_count() is supposed to return the total number of ethtool strings that mlxsw supports. Specifically for names of statistic counters (the only string type that mlxsw supports as of now), that number is stored in MLXSW_SP_PORT_ETHTOOL_STATS_LEN. However, when adding RFC-2891 counters, that define wasn't updated to include the new counters. As a result, ethtool snips out the counters towards the end of the list, which contains per-TC counters, and only the first three traffic classes end up being reported. Fix by adding MLXSW_SP_PORT_HW_RFC_2819_STATS_LEN as appropriate.

Under multicast-aware regime, when assigning traffic class to a packet, the switch doesn't merely take the value prescribed by the QTCT register. For BUM traffic, it instead assigns that value plus 8. ETS elements for TCs 8..15 thus need to be configured as well. Extend mlxsw_sp_port_ets_init() so that it maps each of them to the same subgroup as their corresponding TC from the range 0..7, such that TCs X and X+8 map to the same subgroup. The existing code configures TCs with strict priority. So far this was immaterial, because each TC had its own subgroup. Now that two TCs share a subgroup it becomes important. TCs are prioritized in order of 7, 6, ..., 0, 15, 14, ..., 8: the higher TCs used for BUM traffic end up being deprioritized. Since that's what's needed, keep that configuration as it is, and configure the new TCs likewise. Finally in mlxsw_sp_port_create(), invoke configuration of QTCTM to enable MC-aware mode on each port.

Configure RGCR.usp accordingly so that the device is in sync with the kernel handling. Note that RGCR doesn't allow changing arbitrary parameters mid-operation, however "usp" is exempt and can be reconfigured. Also react to NETEVENT_IPV4_FWD_UPDATE_PRIORITY_UPDATE notifications that signify change in this configuration.

Gal, started with three cleanups to reflect the actual hardware vxlan state - reflect 4789 UDP port default addition to software database - check maximum number of vxlan UDP ports - cleanup an unused member in vxlan work Then Gal provides performance optimization by replacing the vxlan radix tree with a hash table. Measuring mlx5e_vxlan_lookup_port execution time: Radix Tree Hash Table --------------- ------------ ------------ Single Stream 161 ns 79 ns (51% improvement) Multi Stream 259 ns 136 ns (47% improvement) Measuring UDP stream packet rate, single fully utilized TX core: Radix Tree: 498,300 PPS Hash Table: 555,468 PPS (11% improvement) Next, from Saeed, vxlan refactoring to allow sharing the vxlan table between different mlx5 netdevice instances like PF and VF representors, this is done by making mlx5 vxlan interface more generic and decoupling it from PF netdevice structures and logic, then moving it into mlx5 core as a low level interface so it can be used by VF representors, which is illustrated in the last patch of the serious. ==================== Signed-off-by: David S.
