Subject: [net] mac80211: report correct signal for non-dBm values
Message-id: <20091209183614.GD10026@redhat.com>
Patchwork-id: 21829
O-Subject: [RHEL5.5 PATCH] mac80211: report correct signal for non-dBm signal
	values
Bugzilla: 545899

Another one-liner...without this rtl8180 always reports 0 signal.

BZ545899

Upstream patch (adjusted to apply to rhel5.5 w/o an offset):

wireless: correctly report signal value for IEEE80211_HW_SIGNAL_UNSPEC

This part was missed in "cfg80211: implement get_wireless_stats",
probably because sta_set_sinfo already existed and was only handling
dBm signals.
