An MAE port, or m-port, is a port (source/destination for traffic) on the Match-Action Engine (the internal switch on EF100). Representors will use their representee's m-port for two purposes: as a destination override on TX from the representor, and as a source match in 'default rules' to steer representee traffic (when not matched by e.g. a TC flower rule) to representor RX via the parent PF's receive queue.

2022-07-20net: ipa: initialize ring indexes to 0Alex Elder2-10/+13
When a GSI channel is initially allocated, and after it has been reset, the hardware assumes its ring index is 0. And although we do initialize channels this way, the comments in the IPA code don't really explain this. For event rings, it doesn't matter what value we use initially, so using 0 is just fine. Add some information about the assumptions made by hardware above the definition of the gsi_ring structure in "gsi.h". Zero the index field for all rings (channel and event) when the ring is allocated. As a result, that function initializes all fields in the structure. Stop zeroing the index the top of gsi_channel_program(). Initially we'll use the index value set when the channel ring was allocated. And we'll explicitly zero the index value in gsi_channel_reset() before programming the hardware, adding a comment explaining why it's required. For event rings, use the index initialized by gsi_ring_alloc() rather than 0 when ringing the doorbell in gsi_evt_ring_program(). (It'll still be zero, but we won't assume that to be the case.) Use a local variable in gsi_evt_ring_program() that represents the address of the event ring's ring structure. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

2022-07-20mlxsw: spectrum_router: Fix IPv4 nexthop gateway indicationIdo Schimmel1-1/+1
mlxsw needs to distinguish nexthops with a gateway from connected nexthops in order to write the former to the adjacency table of the device. The check used to rely on the fact that nexthops with a gateway have a 'link' scope whereas connected nexthops have a 'host' scope. This is no longer correct after commit 747c14307214 ("ip: fix dflt addr selection for connected nexthop"). Fix that by instead checking the address family of the gateway IP. This is a more direct way and also consistent with the IPv6 counterpart in mlxsw_sp_rt6_is_gateway().
