Subject: [PATCHv2 3/6] RDMA/nldev: Add dellink function pointer
Date: Thu, 6 Oct 2022 04:59:18 -0400 [thread overview]
Message-ID: <20221006085921.1323148-4-yanjun.zhu@linux.dev> (raw)
In-Reply-To: <20221006085921.1323148-1-yanjun.zhu@linux.dev>
From: Zhu Yanjun <yanjun.zhu@linux.dev>
The newlink function pointer is added. And the sock listening on port 4791
is added in the newlink function. So the dellink function is needed to
remove the sock.
Signed-off-by: Zhu Yanjun <yanjun.zhu@linux.dev>
