[dpdk-dev] [PATCH v2 1/2] net/iavf: fix default RSS field for IP fragment packets

[Wenjun Wu <wenjun1.wu@intel.com>]

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.

Fixes: 9e29a278bc0c ("net/iavf: support default RSS for IP fragment")
