Subject: net/iavf: remove support for IP fragment default RSS
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f8d541da5184c91fdec24f1b4713e79e0f837bde;p=dpdk.git

net/iavf: remove support for IP fragment default RSS

To support independent IP fragment default RSS, considerable
additional work need to be done, so we decide to remove this
feature to avoid some unexpected behavior we have observed,
meanwhile user always can use rte_flow to create RSS for IP
fragment packet explicitly.
