Broadcom BCM43142 802.11n (was: please try bwn(4) in -HEAD)

[Juan Ramón Molina Menor]

Hi!

I’ve got a tiny Lenovo S20-30 (Bay Trail-M). It has a Broadcom Wi-Fi NIC:

none2 at pci0:2:0:0:    class=0x028000 card=0x062117aa chip=0x436514e4 
rev=0x01 hdr=0x00
      vendor     = 'Broadcom Corporation'
      device     = 'BCM43142 802.11b/g/n'
      class     = network

Up to date kernel installed this morning:

FreeBSD 11.0-ALPHA3 #1 r301878

I’ve installed the bwn firmware. Firmware modules load correctly at 
boot. kldstat shows:

if_bwn.ko
siba_bwn.ko
bwn_v4_ucode.ko
bwn_v4_lp_ucode.ko
bwn_v4_n_ucode.ko

Unfortunately, the driver is not attaching to the card.

Best regards,
Juan
