Subject: [PATCH net-next v3 0/3] cxgb4: add mirror action support for TC-MATCHALL
Date: Tue, 30 Jun 2020 18:41:27 +0530 [thread overview]
Message-ID: <cover.1593521119.git.rahul.lakkireddy@chelsio.com> (raw)
This series of patches add support to mirror all ingress traffic
for TC-MATCHALL ingress offload.
Patch 1 adds support to dynamically create a mirror Virtual Interface
(VI) that accepts all mirror ingress traffic when mirror action is
set in TC-MATCHALL offload.
Patch 2 adds support to allocate mirror Rxqs and setup RSS for the
mirror VI.
Patch 3 adds support to replicate all the main VI configuration to
mirror VI. This includes replicating MTU, promiscuous mode,
all-multicast mode, and enabled netdev Rx feature offloads.
Thanks,
Rahul
v3:
- Replace mirror VI refcount_t with normal u32 variable in all patches.
- Add back calling cxgb4_port_mirror_start() in cxgb_open(), which
was there in v1, but got missed in v2 during refactoring, in patch
3.
v2:
- Add mutex to protect all mirror VI data, instead of just
mirror Rxqs, in patch 1 and 2.
- Remove the un-needed mirror Rxq mutex in patch 2.
- Simplify the replication code by refactoring t4_set_rxmode()
to handle mirror VI, instead of duplicating the t4_set_rxmode()
calls in multiple places in patch 3.
