Subject: [dpdk-dev] [PATCH 04/14] net/mlx5: add getting IB ports number for multiport IB
Date: Thu, 21 Mar 2019 08:11:18 +0000	[thread overview]
Message-ID: <1553155888-27498-5-git-send-email-viacheslavo@mellanox.com> (raw)
Message-ID: <20190321081118.ZnR6b10BNQivYVrnYKc-cpHQPA2Lcfd9kmYF2qFERzc@z> (raw)
In-Reply-To: <1553155888-27498-1-git-send-email-viacheslavo@mellanox.com>

There is the routine mlx5_nl_portnum() added to get
the number of ports of multiport Infiniband device.
It is assumed the Uplink/VF representors are attached
on this ports.
