Subject: Subject: [PATCH] Advertise PPPoE MTU (resubmit).
Date: Tue, 26 Sep 2006 06:31:38 -0500	[thread overview]
Message-ID: <11592702983561-git-send-email-mostrows@earthlink.net> (raw)

PPPoE must advertise the underlying device's MTU via the ppp channel
descriptor structure, as multilink functionality depends on it.
