Message-Id: <1384693524-20599-2-git-send-email-albeu@free.fr> Date: Sun, 17 Nov 2013 14:05:24 +0100 From: Alban Bedel <albeu@...e.fr> To: linux-kernel@...r.kernel.org Cc: netdev@...r.kernel.org, jgarzik@...ox.com, davem@...emloft.net Subject: [PATCH 2/2] 8139too: Allow using the largest possible MTU This driver allows MTU up to 1518 bytes which is not enought to run batman-adv. Simply raise the maximum packet size up to the maximum allowed by the transmit descriptor, 1792 bytes, giving a maximum MTU of 1774 bytes.
