This patch removes redundant default RSS field for IP fragment packets,
only src MAC address and dst MAC address are needed.

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.
