From 19d30e02998ef1eb9f82a7d3ce9b4a97dba5aa13 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Sat, 15 Mar 2008 21:38:07 +0100 Subject: rt2x00: Add dev_flags to rx descriptor The rxdone_entry_desc structure contains 3 fields which are always 1 or 0. We can safe 8 bytes by replacing them with a single dev_flags fields which contain the flags for those settings. Additionally we can remove the OFDM flag since it is no longer used since the introduction of the SIGNAL_PLCP flag. Signed-off-by: Ivo van Doorn Signed-off-by: John W.
