Do we actually need three signatures to match? Something like, static struct ixgbe_mat_field ixgbe_tcp_fields[] = { {.off = 0, .mask = 0xffffffff, .val = ixgbe_mat_prgm_ports, .type = IXGBE_ATR_FLOW_TYPE_TCPV4}, {.off = 0, .mask = 0xffff0000, .val = ixgbe_mat_prgm_dport, .type = IXGBE_ATR_FLOW_TYPE_TCPV4}, {.off = 0, .mask = 0x0000ffff, .val = ixgbe_mat_prgm_sport, .type = IXGBE_ATR_FLOW_TYPE_TCPV4}, { .val = NULL } /* terminal node */ }; Also just a reminder if we get multiple fields in a ixgbe_mat_field struct we need to abort out of the for loop in the cls_u32 configure function. Actually we can probably just push that as its own patch to make the core function more versatile/usable. Thanks, John

No. This will not break specifying only src or dst port. The value/mask for the unspecified port will be set to zero. So it should be fine. For ex: match tcp src 1024 ffff match tcp dst 80 ffff => match 04000050/ffffffff at nexthdr+0 match tcp src 1024 ffff => match 04000000/ffff0000 at nexthdr+0 match tcp dst 80 ffff => match 00000050/0000ffff at nexthdr+0 > Do we > actually need three signatures to match?

If not, why are you re-sending a patch that is already in my queue? If so, where is the changelog so we know what changed in this updated v2 of the patch?

No. This is another patch that fixes other issues on top of the previous one. Thanks Sridhar

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. Remove the incorrect check for mask in ixgbe_configure_clsu32() Tested with the following filters: #tc qdisc add dev p4p1 ingress #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \ handle 800:0:1 u32 ht 800: \ match ip dst 11.0.0.1/24 match ip src 11.0.0.2/24 action drop #tc filter del dev p4p1 parent ffff: protocol ip prio 99 \ handle 800:0:1 u32 #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 Signed-off-by: Sridhar Samudrala <sridhar.samudrala@intel.com> --- drivers/net/ethernet/intel/ixgbe/ixgbe_main.c | 3 +-- drivers/net/ethernet/intel/ixgbe/ixgbe_model.h | 17 ++++------------- 2 files changed, 5 insertions(+), 15 deletions(-)
