Message-Id: <20100904042815.2655.71537.sendpatchset@jupiter1-ltc-lp2.austin.ibm.com> Date: Fri, 03 Sep 2010 23:28:15 -0500 From: Santiago Leon <santil@...ux.vnet.ibm.com> To: netdev@...r.kernel.org Cc: brking@...ux.vnet.ibm.com, Santiago Leon <santil@...ux.vnet.ibm.com>, anton@...ba.org Subject: [patch 03/21] ibmveth: Remove LLTX The ibmveth adapter needs locking in the transmit routine to protect the bounce_buffer but it sets LLTX and forgets to add any of its own locking. Just remove the deprecated LLTX option. Remove the stats lock in the process.
