[dpdk-dev] [PATCH v4] net/ixgbe: fix l3fwd start failed on VF

[Yanglong Wu]

VF can't run in multi queue mode, if nb_q_per_pool was set as 1.
Nb_q_per_pool is passed through to max_rx_q and max_tx_q in VF.
So if nb_q_per_pool is equal to 1, max_rx_q and max_tx_q can't be more
than 1 and VF multi queue mode will fail.

Fixes: 27b609cbd1c6 (ethdev: move the multi-queue mode check)
