Hi All,
My motherboard has a built-in NIC, a BCM5702. (Broadcom 10/100/GigE)
none0@pci0:9:0: class=0x020000 card=0x80a81043 chip=0x440114e4 rev=0x01 hdr=0x00
vendor = 'Broadcom Corporation'
class = network
subclass = ethernet
The chipID wasn't in if_bgereg.h, so I added -
#define BCOM_DEVICEID_BCM5702 0x4401
and a define in the probe list in if_bge.c
static struct bge_type bge_devs[] = {
{ ALT_VENDORID, ALT_DEVICEID_BCM5700,
"Broadcom BCM5700 Gigabit Ethernet" },
{ ALT_VENDORID, ALT_DEVICEID_BCM5701,
"Broadcom BCM5701 Gigabit Ethernet" },
{ BCOM_VENDORID, BCOM_DEVICEID_BCM5700,
"Broadcom BCM5700 Gigabit Ethernet" },
-> { BCOM_VENDORID, BCOM_DEVICEID_BCM5702,
-> "Broadcom BCM5702 Gigabit Ethernet" },
I rebuilt the kernel, and now get the following PANIC on load of the
if_bge module.
bge0: <Broadcom BCM5702 Gigabit Ethernet> mem 0xde800000-0xde801fff irq 9 at device 9.0 on pci0
bge0: firmware handshake timed out

From the glossies BCM5702 ASIC looks like a more streamlined (smaller
package) version of the BCM5701 ASIC. They even mention having official
Linux 2.2/4 support, and I did see a commit of DEVICEID additions on
kernel.org from back in February.
So I expected that all I'd need to do for -stable was add the device id
pair to the driver probe but ... :(
I'd be willing to be a guinea pig if someone had an idea as to what I'm
missing here ;)
Thanks, :)
Andrew.
