Subject: [PATCH 05/15] ehea: Dont check NETIF_F_TSO in TX path
Date: Thu, 12 May 2011 10:52:18 +1000 [thread overview]
Message-ID: <20110512005622.940842280@samba.org> (raw)
In-Reply-To: 20110512005213.897432612@samba.org
[-- Attachment #1: ehea_6.patch --]
[-- Type: text/plain, Size: 808 bytes --]
It seems like the ehea xmit routine and an ethtool change of TSO
mode could race, resulting in corrupt packets. Checking gso_size
is enough and we can use the helper function.
