From 22dd74950172dc8979576e2bef3b439f20ef0b05 Mon Sep 17 00:00:00 2001 From: Jamal Hadi Salim Date: Sun, 16 Sep 2007 14:40:49 -0700 Subject: [NET]: migrate HARD_TX_LOCK to header file HARD_TX_LOCK micro is a nice aggregation that could be used in other spots. move it to netdevice.h Also makes sure the previously superflous cpu arguement is used.
