[dpdk-dev] [PATCH v3 2/2] app/testpmd: only config supported RSS hash types

[Xueming Li <xuemingl@mellanox.com>]

"port config all rss all" command will fail on PMD that not support any
of hard coding RSS hash types. This patch changed hard coding hash types
to supported types retrieved from device info.
