From 0a5ec96ad68516582023a877aceff9db7636d141 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sun, 14 Dec 2008 15:05:42 +0100 Subject: p54: remove free_on_tx parameter This patch simplifies the tx code a bit and will be necessary for the upcoming stlc45xx<->p54 port. In detail: we no longer have to tell all back-end drivers directly, if we want to free a frame right after it was send to the firmware, or if we do it in the library callback later.
