Subject: [PATCH for-next 2/4] RDMA/efa: Be consistent with modify QP bitmask
Date: Fri, 31 Jul 2020 09:04:18 +0300 [thread overview]
Message-ID: <20200731060420.17053-3-galpress@amazon.com> (raw)
In-Reply-To: <20200731060420.17053-1-galpress@amazon.com>
The modify QP bitmask was not consistent with other bitmasks used in the
device interface. Remove the bitmask enum and allow usage with
EFA_GET/SET.
