Subject: [dpdk-dev] [PATCH v3] net/ixgbe: fix l3fwd start failed on PF
Date: Mon, 20 Nov 2017 10:29:51 +0800	[thread overview]
Message-ID: <20171120022951.151510-1-yanglong.wu@intel.com> (raw)
In-Reply-To: <20171120015332.150668-1-yanglong.wu@intel.com>

L3fwd start failed on PF, for tx_q check failed.
That occurred when the SRIOV is active and tx_q > rx_q.
The tx_q is equal to nb_q_per_pool. The number of nb_q_per_pool
should equeal to max number of queues supported by HW not nb_rx_q.

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