[dpdk-dev] [PATCH v2] app/testpmd: fix RSS by setting mq_mode

[Daniel Kan <dan@nyansa.com>]

The mq_mode was not set when rxq is > 1; it's defaulted to ETH_MQ_RX_NONE.
As a result, RSS remains inactive. The fix is to set mq_mode to ETH_MQ_RX_RSS
when rxq is > 1 and hf is non-zero.

This bug was introduced by commit 243db2ddee3094a2cb39fdd4b17e26df4e7735e1
igb/ixgbe: ETH_MQ_RX_NONE should disable RSS
