Subject: [patch 094/149] ath5k: retain promiscuous setting

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Bob Copeland <me@...copeland.com>

commit 6b5dcccb495b66b3b0b9581cdccfed038e5d68a2 upstream.

Commit 56d1de0a21db28e41741cfa0a66e18bc8d920554, "ath5k: clean up
filter flags setting" introduced a regression in monitor mode such
that the promisc filter flag would get lost.

Although we set the promisc flag when it changed, we did not
preserve it across subsequent calls to configure_filter.  This patch
restores the original functionality.
