Fix support for 16 bit source/dest port matches in ixgbe model. u32 uses a single 32-bit key value for both source and destination ports starting at offset 0. So replace the 2 functions with a single function that takes this key value/mask to program both source and dest ports. Verified with the following filter: #tc qdisc add dev p4p1 ingress #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 1: u32 divisor 1 #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 800:0:10 u32 ht 800: link 1: \ offset at 0 mask 0f00 shift 6 plus 0 eat match ip protocol 6 ff #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 1:0:10 u32 ht 1: \ match tcp src 1024 ffff match tcp dst 80 ffff action drop #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 1:0:11 u32 ht 1: \ match tcp src 1025 ffff action drop #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 1:0:12 u32 ht 1: \ match tcp dst 81 ffff action drop Signed-off-by: Sridhar Samudrala <sridhar.samudrala@intel.com> Acked-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
