Subject: [PATCH rdma-next 07/10] RDMA/efa: Allow passing of optional access flags for MR registration
Date: Wed,  8 Jan 2020 20:05:37 +0200	[thread overview]
Message-ID: <1578506740-22188-8-git-send-email-yishaih@mellanox.com> (raw)
In-Reply-To: <1578506740-22188-1-git-send-email-yishaih@mellanox.com>

From: Michael Guralnik <michaelgur@mellanox.com>

As part of adding a range of optional access flags that drivers need to
be able to accept, mask this range inside efa driver.
This will prevent the driver from failing when an access flag from
that range is passed.
