  Previously, hash value is calculated by src IP address, dst IP address
and IP ID. However, default RSS field only needs src and dst IP address.

This patch removes IP ID from default RSS field for IP fragment packets to
improve default RSS configuration.

Fixes: 4027fffe86f4 ("net/ice: support default RSS for IP fragment packet")
