Subject: [dpdk-dev] [PATCH v2] net/ixgbe: fix l3fwd start failed on VF
Date: Mon, 20 Nov 2017 10:00:34 +0800	[thread overview]
Message-ID: <20171120020034.150717-1-yanglong.wu@intel.com> (raw)
In-Reply-To: <20171102161031.167892-1-yanglong.wu@intel.com>

VF can't run in multi queue mode, if nb_q_per_pool was set as 1.
The value of 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 to specific drivers)
