[v2,04/11] app/testpmd: support IPv6 fragments
Checks
Commit Message
rte_flow update, following RFC [1], introduced frag_ext_exist field for
IPv6 header item, used to indicate match on fragmented/non-fragmented
packets.
This patch updates testpmd CLI to support the new field.
To match on non-fragmented IPv6 packets, need to use pattern:
... ipv6 frag_ext_exist spec 0 frag_ext_exist mask 1 ...
To match on fragmented IPv6 packets, need to use pattern:
... ipv6 frag_ext_exist spec 1 frag_ext_exist mask 1 ...
To match on any IPv6 packets, the frag_ext_exist field should
not be specified for match.
