Subject: i40e: remove flex payload from input selection
X-Git-Tag: spdx-start~7186
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=59602906db3322b2e86744afdbf994f89df88c2a;p=dpdk.git

i40e: remove flex payload from input selection

In this patch, flex payload is removed from valid fdir input set
values. This is because all flex payload configuration can be set
in struct rte_fdir_conf during device configure phase, which is
a more flexible way of setting this up.
