Same comments with first patch.
Impact is not clear, and this patch seems a little different from first path,
this clears one flag from 'cfg.hash_flds', why and if this is not causing any
impact (that is what I understand from description) can you explain in the
commit log why it doesn't change the behavior of the code?
Also again long patch title.

Previously IP ID field is supported in default RSS for IP fragment packets.
Actually it is not expected.
This patch removes redundant default RSS field for IP fragment packets.
The default RSS only needs to support the src and dst IP fields.

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.
