From efacb309b50073a79ae604949a31509cd8b507ab Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Tue, 10 Apr 2012 18:34:43 +0000 Subject: rtnetlink & bonding: change args got get_tx_queues Change get_tx_queues, drop unsused arg/return value real_tx_queues, and use return by value (with error) rather than call by reference. Probably bonding should just change to LLTX and the whole get_tx_queues API could disappear! Signed-off-by: Stephen Hemminger Signed-off-by: David S.
