#1013: Broadcom BCM4312 / bwn

Component:  Network Manager      |    Version:  10.0-RELEASE
 Keywords:  Broadcom bwn driver  |
 I'm trying to install PC-BSD 10-Release for amd64 on a laptop, and I
 encounter a problem with the network card, which is not seen by the
 network manager.

 It's well detected; from dmesg:

 warning: KLD '/boot/kernel/siba_bwn.ko' is newer than the linker.hints
 siba_bwn0: <Broadcom BCM4312 802.11a/b/g Wireless> mem
 0xf6000000-0xf6003fff irq 19 at device 0.0 on pci3
 siba_bwn0: unsupported coreid (USB 1.1 Host)
 bwn0 on siba_bwn0
 bwn0: WLAN (chipid 0x4311 rev 13) PHY (analog 4 type 2 rev 9) RADIO (manuf
 0x17f ver 0x2050 rev 2)
 bwn0: DMA (64 bits)
 bwn0: Using 1 MSI messages

 The driver is loaded:

 # kldstat | grep bwn
 17 1 0xffffffff82c23000 3080b if_bwn.ko
 1 1 0xffffffff82c54000 6d27 siba_bwn.ko

 According to bwn(4) on FreeBSD-10:

 This driver requires firmware to be loaded before it will work. The
 ports/net/bwn-firmware-kmod port needs to be installed before ifconfig(8)
 will work. Most cases you need to use bwn_v4_ucode module but if you are
 a LP (low power) PHY user please uses bwn_v4_lp_ucode module.

 This is a restricted package, so I built it on a FreeBSD 10-Release
 machine and installed it on this PC-BSD laptop, but I cannot load it:

 # kldload /boot/modules/bwn_v4_ucode.ko
 kldload: can't load /boot/modules/bwn_v4_ucode.ko: Exec format error
 # kldload /boot/modules/bwn_v4_lp_ucode.ko
 kldload: can't load /boot/modules/bwn_v4_lp_ucode.ko: Exec format error

 Am i missing something? Are these restricted firmware provided somewhere
 for PC-BSD?
