[PATCH rdma-next 4/9] RDMA/uapi: Add ECE definitions to UCMA

[Leon Romanovsky <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.
