p54: better rssi->dbm conversion for longbow phys
This patch should fix the dodgy signal and noise value reports for most longbow (p54spi) users: e.g.: (an older tcpdump extract) > 2.0 Mb/s 2437 MHz (0x00a0) -49dB signal -41dB noise > 1.0 Mb/s 2437 MHz (0x00a0) 4dB signal -41dB noise The formula is taken from stlc45xx: http://gitorious.org/stlc45xx/mainline/blobs/master/stlc45xx.c#line1199 Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.
