Subject: [RFC PATCH 7/7] sunrpc: Connect to a new IP address provided by the user
Date: Mon, 11 Jan 2021 16:41:43 -0500	[thread overview]
Message-ID: <20210111214143.553479-8-Anna.Schumaker@Netapp.com> (raw)
In-Reply-To: <20210111214143.553479-1-Anna.Schumaker@Netapp.com>

From: Anna Schumaker <Anna.Schumaker@Netapp.com>

We preserve the same port number, rather than providing a way to change
it. This keeps the implementation simpler for now.
