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.

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. And packet id field
for RSS is not correctly added when IP fragment is enabled. To fix this
issue, this patch only selects one of the above two segment header types
based on rss types.
