Hi Dave, Jakub,

This series provides updates to mlx5 CT (connection tracking) offloads
For more information please see tag log below.

Please pull and let me know if there is any problem.

The following conflict is expected when net is merged into net-next:
to resolve just use the hunks from net-next.

<<<<<<< HEAD (net-next)

======= (net)
	mlx5_tc_ct_entry_del_rules(ct_priv, entry);
	kfree(entry);
>>>>>>> b1a7d5bdfe54c98eca46e2c997d4e3b1484a49af

Thanks,
Saeed.

  net/mlx5e: CT: Fix releasing ft entries (2020-07-09 19:51:17 -0700)

----------------------------------------------------------------
mlx5-updates-2020-07-09

mlx5 connection tracking offloads updates:

1)  Restore CT state from lookup in zone instead of tupleid

    On a miss, Use this zone + 5 tuple taken from the skb, to lookup the CT
    entry and restore it, instead of the driver allocated tuple id.

    This improves flow insertion rate by avoiding the allocation of a header
    rewrite context to maintain the tupleid.

2) Re-use modify header HW objects for identical modify actions.

3) Expand tunnel register mappings
   Reg_c1 is 32 bits wide. Before this patchset, 24 bit were allocated
   for the tuple_id,  6 bits for tunnel mapping and 2 bits for tunnel
   options mappings.

   Restoring the ct state from zone lookup instead of tuple id requires
   reg_c1 to store 8 bits mapping the ct zone, leaving 24 bits for tunnel
   mappings.

   Expand tunnel and tunnel options register mappings to 12 bit each.

4) Trivial cleanup and fixes.
