l2: fix vxlan src port entropy with mpls payload
l2 tunnels like vxlan, gtpu, geneva use vnet_l2_compute_flow_hash() to compute flow hash for udp src port entropy. In case of inner mpls tunnels to the same lsr ethernet src and dst macs are the same, so l2 flow hash is also the same leading to no src port entropy and the only rss queue overflow on receiver side. Fix it for all the possible vnet_l2_compute_flow_hash callers by making mpls playload hash in additon to ip4/ip6. Visible performance impact is not expected as it's only one check for mpls ethertype for common cases. Type: fix Signed-off-by: Vladislav Grishenko <themiron@yandex-team.ru> Change-Id: I69153d42fb3d7c094a670c674fac8d14039c626a
