[dpdk-dev] [PATCH v1] net/ice: fix wrong IP RSS configuration template

Fri May 7 11:52:27 CEST 2021
To enable IP fragment RSS hash, ICE_FLOW_SEG_HDR_IPV_FRAG is added to the
IP RSS configuration template, together with ICE_FLOW_SEG_HDR_IPV_OTHER.
It will cause error when associating flow profile. To fix this issue,
this patch only selects one of the above two segment header types based
on rss types.
Fixes: 672f321d09ed ("net/ice: support RSS hash for IP fragment")
