Subject: [PATCH rdma-next v2 2/7] RDMA/uapi: Add ECE definitions to UCMA
Date: Mon, 13 Apr 2020 17:15:33 +0300	[thread overview]
Message-ID: <20200413141538.935574-3-leon@kernel.org> (raw)
In-Reply-To: <20200413141538.935574-1-leon@kernel.org>

From: Leon Romanovsky <leonro@mellanox.com>

ECE parameters are used to perform handshake between different
CMID nodes in order to allow extra connection setup supported
by those two nodes. The data is provided by rdma_connect()
for the client and rdma_get_events() for the server.
