From cf966838cd5596ca61d3e9949050442a943f6238 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 28 Aug 2007 17:01:54 -0400 Subject: [MAC80211]: use switch statement in tx code The transmit code needs to set the addresses depending on the interface type, a likely() for AP/VLAN is quite wrong since most people will be using STA; convert to a switch statement to make it look nicer.
