cxgb4: add mirror action to TC-MATCHALL offload
Add mirror Virtual Interface (VI) support to receive all ingress
mirror traffic from the underlying device. The mirror VI is
created dynamically, if the TC-MATCHALL rule has a corresponding
mirror action. Also request MSI-X vectors needed for the mirror VI
Rxqs. If no vectors are available, then disable mirror VI support.
v3:
- Replace mirror VI refcount_t with normal u32 variable.
v2:
- Add mutex to protect all mirror VI data, instead of just
mirror Rxqs.
