From d0a5aab8edfccb067bc936bced8fba1684ab3023 Mon Sep 17 00:00:00 2001 From: adrian Date: Wed, 31 Oct 2012 21:03:55 +0000 Subject: HAL updates! * Add some more ANI spur immunity levels. * For AR5111 radios attached to an AR5212, limit the 5GHz channels that are available. A later revision of the AR5111 supports the 4.9GHz PSB channels but right now there's no check in place for the radio revision. If someone wants PSB support on AR5212+AR5111 radios then please let me know and I'll add the relevant version check.
