Hi Arend,
In OpenWrt someone reported that he has a BCM4313 with the PCI id
14e4:4313 [0]. The b43 wiki [1] says this was used for a BCM4311 with
just ieee80211a support.
Is it correct that BCM4313 also uses this PCI id, this chip was was
directly soldered onto a router? Is the b43 wiki wrong and 14e4:4313 was
not used for the BCM4311 or was this PCI id reused for a different device?
I am planing to prepare a patch adding support for a BCM4313 with the
PCI ID of 14e4:4313 and I will ignore that there could be some BCM4311
with this PCI id.

That is what I found over here as well.

It is weird that this comes up with PCI id 0x4313. The chip id is read
from chipcommon and indeed returns 0x4313. The core revisions that bcma
finds indicate also that this is indeed a bcm4313.

You mean a patch in brcmsmac? Maybe brcms_c_chipmatch_pci() should check
the chip id as well (like brcms_c_chipmatch_soc()).

Could it be that this is some default PCI id which is normally changed
by a vendor to something else? I have seen the BCM43224 with the PCI id
14e4:a8d8 only on routers expect after I introduced a error in bcma and
all the BCM43224 turned to have this PCI id. ;-)

Yes I want to add this to the pci ids of bcma and to brcmsmacs
brcms_c_chipmatch_pci() function.
