Call for Test and Review: bwn(4) - another Broadcom Wireless driver

[Buganini]

Hi, I got a Lenovo G450 with
siba_bwn0 at pci0:4:0:0:	class=0x028000 card=0x04b514e4 chip=0x431514e4
rev=0x01 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'Broadcom Wireless b/g (BCM4315/BCM22062000)'
    class      = network


4315 is not in supported list, but however the driver took the device
bwn_v4_lp_ucode.ko was not loaded automatically, so I loaded it manually
ifconfig scan seem freeze, I can `ifconfig list scan` later  and found
access point correctly,
but I can't associate with them, it just keep scanning channels.


My uname -ai:
FreeBSD Zeta.twbbs.org 9.0-CURRENT FreeBSD 9.0-CURRENT #1: Fri Mar 26
03:42:08 CST 2010     root at Zeta.twbbs.org:/usr/obj/usr/src/sys/ZETA
i386 Zeta


Is this bug or just lack of support?
