Subject: [dpdk-dev] [RFC 01/10] net/mlx5: add multiport IB device port structure
Date: Thu, 28 Feb 2019 18:02:56 +0000	[thread overview]
Message-ID: <1551376985-11096-2-git-send-email-viacheslavo@mellanox.com> (raw)
In-Reply-To: <1551376985-11096-1-git-send-email-viacheslavo@mellanox.com>

The Mellanox NICs support SR-IOV and have E-Switch feature.
When SR-IOV is set up in switchdev mode and E-Switch is enabled
we have so called VF representors in the system. All representors
belonging to the same E-Switch are created on the basis of the
single PCI function and with current implementation each representor
has its own dedicated Infiniband device and operates within its
own Infiniband context. It is proposed to provide representors
as ports of the single Infiniband device and operate on the
shared Infiniband context saving various resources. This patch
introduces appropriate structures.
