bwn updates - now BCM4321, BCM4322

[Björn Jonare]

Hi,  

First let me say that I very much appreciate your work on bwn. Broadcom devices are, alas all too common :( Anyway I dug an old iMac out of storage and installed a recent CURRENT (r300836) since I knew the wifi chip in it to be some variant of the BCM4322.

After uncommenting all needed lines (?) in the Makefile regarding GNU PHY support I loaded bwn_v4_ucode,  bwn_v4_n_ucode and if_bwn. Upon checking dmesg I got this:

siba_bwn0: <Broadcom BCM4321 802.11a/b/g/n Wireless> mem 0xd0200000-0xd0203fff,0xd0000000-0xd00fffff irq 17 at device 0.0 on pci3
siba_bwn0: warn: multiple PCI(E) cores
siba_bwn0: unsupported coreid (USB 1.1 Host)
bwn0 on siba_bwn0
bwn0: failed
device_attach: bwn0 attach returned 6



So, the driver doesn’t attach :(

Since my understanding of drivers is well, lacking, is there anything I could do to get this specific version of BCM4322 to work[1]? I would be glad to provide any information needed.


[1] That is to get the driver to attach. I have no illusions regarding functionality, this is after all a Broadcom chipset!
