amd64/184304: Broadcom NetXtreme BCM57786 Gigabit Ethernet NIC not working

[Sastry Tumuluri]

After the following steps,
1. Apply the patch
2. make buildkernel && make installkernel
3. add the interface to /etc/rc.conf
4. reboot
The interface comes up as bge0 and it works.

Now, /var/run/dmesg.boot shows:
bge0: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev.
0x57766001> mem 0xb0410000-0xb041ffff, 0xb0420000-0xb042ffff irq 18 at
device 0.0 on pci1
bge0: CHIP ID 0x57766001; ASIC REV 0x57766; CHIP REV 0x577660; PCI-E
miibus0: <MII bus> on bge0
brgphy0: <BCM57765 1000BASE-T media interface> PHY 1 on miibus0
brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT,
1000baseT-master, 1000baseT-FDX, 1000baseT-FDX-master, auto, auto-flow
bge0: Ethernet address: aa:bb:cc:dd:ee:ff

Notes:
1. I expected to see BCM57786 (pciconf -lv shows this even now) in the
messages but there isn't any. The chip number, revision and card
references from pciconf don't seem to match with dmesg.
2. In dmesg, "brgphy0:" line refers to <BCM57765 1000BASE-T media
interface>  but pciconf refers to BCM57765 as "Memory Card Reader";
not sure what the 1000BASE-T in dmesg is about.


Cheers,
