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

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.
