I have found one ssb bug that was keeping b43legacy from receiving.
The one-line patch is as follows:
Index: wireless-testing/drivers/ssb/driver_pcicore.c
===================================================================
--- wireless-testing.orig/drivers/ssb/driver_pcicore.c
+++ wireless-testing/drivers/ssb/driver_pcicore.c
@@ -569,7 +569,7 @@ int ssb_pcicore_dev_irqvecs_enable(struc
} else {
tmp = ssb_read32(dev, SSB_TPSFLAG);
tmp &= SSB_TPSFLAG_BPFLAG;
- intvec |= tmp;
+ intvec |= (1 << tmp);
}
ssb_write32(pdev, SSB_INTVEC, intvec);
}
With that patch in place, "iwlist scan" now sees the local AP's, but
still no transmit.
I now have two interfaces that are PCI, but not Cardbus, that can
receive but not transmit. They are this BCM4301 using b43legacy, and
an ASUS WL-138G V2 card using b43 that Donald from Australia sent me.
It is a BCM4318 with a rev 0xC PCI core, and a rev 0x9 802.11 core.
