From e8cb7eb473ac47703282db6f90b4926f31cdf376 Mon Sep 17 00:00:00 2001 From: Santiago Leon Date: Fri, 3 Sep 2010 18:28:15 +0000 Subject: 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. Signed-off-by: Anton Blanchard Signed-off-by: Santiago Leon Signed-off-by: David S.
