From 84f10708f73254878246772cead70a2eb6a123f2 Mon Sep 17 00:00:00 2001 From: Thomas Pedersen Date: Thu, 12 Jul 2012 16:17:33 -0700 Subject: cfg80211: support TX error rate CQM Let the user configure serveral TX error conection quality monitoring parameters: % error rate, survey interval, and # of attempted packets. On exceeding the TX failure rate over the given interval, the driver will send a CQM notify event with the actual TX failure rate and packets attempted.

Rodriguez" Date: Thu, 12 Jul 2012 11:49:18 -0700 Subject: cfg80211: add cellular base station regulatory hint support Cellular base stations can provide hints to cfg80211 about where they think we are. This can be done for example on a cell phone. To enable these hints we simply allow them through as user regulatory hints but we allow userspace to clasify the hint as either coming directly from the user or coming from a cellular base station. This option is only available when you enable CONFIG_CFG80211_CERTIFICATION_ONUS. The base station hints themselves will not be processed by the core unless at least one device on the system supports this feature. Signed-off-by: Luis R.
