Subject: [Patch v4 07/12] net: mana: Export Work Queue functions for use by RDMA driver
Date: Wed, 15 Jun 2022 19:07:15 -0700 [thread overview]
Message-ID: <1655345240-26411-8-git-send-email-longli@linuxonhyperv.com> (raw)
In-Reply-To: <1655345240-26411-1-git-send-email-longli@linuxonhyperv.com>
From: Long Li <longli@microsoft.com>
RDMA device may need to create Ethernet device queues for use by Queue
Pair type RAW. This allows a user-mode context accesses Ethernet hardware
queues. Export the supporting functions for use by the RDMA driver.
