Because the VF must be capable of configuring RSS, so add RSS configuration
for iavf, VFs could add or delete a RSS rule base on the PF's capability.
The supported protocol rss input set as below.
l2-src-only/
l2-dst-only/
svlan/
cvlan/
ipv4/
ipv6/
l3_src_only/
l3_dst_only/
l2tpv3/
esp/
ah/
pfcp/
gtpu down/
gtpu up/
udp/
tcp/
sctp/
use tespmd for example:
testpmd> flow create 0 ingress pattern eth / ipv4 / end actions rss types
l3-src-only end key_len 0 queues end / end
use scapy for example:
> sendp(Ether(dst="00:01:23:45:67:01")/IP(src=RandIP())/Raw('x'*20),iface="ens785f1",loop=1,inter=0.3)
the expect result:
the rss hash works and the packets will go to difference queue for load balance.
This patchset depends on below patch sets.

add generic filter support for iavf
(2)http://patches.dpdk.org/project/dpdk/list/?series=9280
