Subject: [net-next PATCH v5 0/2] octeontx2: Multicast/mirror offload changes

This patchset includes changes to support TC multicast/mirror offload.

Patch #1: Adds changes to support new mailbox to offload multicast/mirror
offload.

Patch #2: Adds TC related changes which uses the newly added mailboxes to
offload multicast/mirror rules.

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
