Subject: [Patch v2 07/12] net: mana: Export Work Queue functions for use by RDMA driver
Date: Tue, 24 May 2022 01:56:07 -0700	[thread overview]
Message-ID: <1653382572-14788-8-git-send-email-longli@linuxonhyperv.com> (raw)
In-Reply-To: <1653382572-14788-1-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.
