[dpdk-dev] [PATCH 01/22] net/ice: support RSS hash for IP fragment
Wenjun Wu

Tue Aug 3 10:37:56 CEST 2021
[ upstream commit f1ea76eb63944a65e9e0bbc32244bc7c8b4fbd1d ]
[ upstream commit 664b8eb745b9b6249231cea2f2bc6ff4d4b6bc40 ]
[ upstream commit 8434528175614f4cc8ab25fd28560848d8999605 ]
New pattern and RSS hash flow parsing are added to handle fragmented
IPv4/IPv6 packet.
This patch is not for LTS upstream, just for customer to cherry-pick.
