[dpdk-dev] [PATCH] app/testpmd: fix testpmd failure due to RSS offload check

[Qi Zhang]

After add RSS hash offload check, default rss_hf will fail on
devices that not support all bits, the patch take rss_hf as
a suggest value and only set bits that device supported base on
rte_eth_dev_get_info.

Fixes: 527624c663f8 ("ethdev: add supported hash function check")
