Suman Ghosh (2):
octeontx2-af: Add new mbox to support multicast/mirror offload
octeontx2-pf: TC flower offload support for mirror

v5 changes:
- Updated patch#1.
Using hlist_for_each_entry_safe() in function nix_add_mce_list_entry()
for node deletion.

v4 changes:
- Updated pacth#1 based on comments from Paolo. The major change is to
simplify mutex_lock/unlock logic in function
rvu_mbox_handler_nix_mcast_grp_update(),
rvu_mbox_handler_nix_mcast_grp_destroy() and
rvu_nix_mcast_flr_free_entries().
Added one extra variable in the mailbox to indicate if the
update/delete request is from AF or not. If AF is requesting for
update/delete then the caller is taking the lock.

v3 changes:
- Updated patch#1 based on comments from Wojciech and Simon.
The comments were mostly based on some missed mutex_unlock and
code reorganization.

v2 changes:
- Updated small nits based on review comments from Wojciech Drewek
