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.
That is what I found over here as well.
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?
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.
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.
You mean a patch in brcmsmac? Maybe brcms_c_chipmatch_pci() should check the chip id as well (like brcms_c_chipmatch_soc()).
Regards, Arend
