[v6,4/5] app/testpmd: support IPv6 fragments
Checks
Commit Message
rte_flow update, following RFC [1], introduced has_frag_ext 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 has_frag_ext spec 0 has_frag_ext mask 1 ...
To match on fragmented IPv6 packets, need to use pattern:
... ipv6 has_frag_ext spec 1 has_frag_ext mask 1 ...
To match on any IPv6 packets, the has_frag_ext field should
not be specified for match.
