>Description:
I'm having problems with getting the wired Atheros network card working on my
new laptop (Dell N7010). The pciconf output says the device ID is 0x2060,
which from the dev/alc/if_alcreg.h on the CVSweb browser indicates it is an
AR8152.
I'm running 8.1-RELEASE but its version of alc doesn't support this card. So I
grabbed the version of if_alc.c, if_alcreg.h, and if_alcvar.h from Aug. 20th
2010 which added support, but now after using dhclient or manually assigning an
IP my computer completely locks up. A message about the interface going down,
and then a second one about it coming back up are the last things I see. No
error messages come up nor are written to /var/log/messages.
I also tried even more recent versions from the RELENG_8_2 branch and had to
update some files in dev/mii and sys/net/if_media.h but... same results.
I have an Intel i5 processor and I'm using the amd64 architecture. GENERIC
kernel or a modified one to remove unneeded stuff makes no difference.
Here is the pciconf output after updating alc:
alc0@pci0:4:0:0: class=0x020000 card=0x04571028 chip=0x20601969 rev=0xc1
hdr=0x00
vendor = 'Attansic (Now owned by Atheros)'
class = network
subclass = ethernet
bar [10] = type Memory, range 64, base 0xf0400000, size 262144, enabled
bar [18] = type I/O Port, range 32, base 0x2000, size 128, enabled
cap 01[40] = powerspec 3 supports D0 D3 current D0
cap 05[48] = MSI supports 1 message, 64 bit enabled with 1 message
cap 10[58] = PCI-Express 1 endpoint max data 128(4096) link x1(x1)
cap 03[6c] = VPD
with plain 8.1-RELEASE it's similar but with none3@" replacing
"alc0@" and the cap 05 line doesn't say "enabled with 1 message".
The ifconfig output (with the newer driver) is:
alc0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=c3198<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MCAST,WOL_MAGIC,VLAN_HWTSO,LINKSTATE>
ether f0:4d:a2:56:b9:48
media: Ethernet autoselect
I also tried both the i386 and amd64 bootonly CD's for 8.2-RC2 and the same
thing still happens if I give an IP address to alc0 with ifconfig at the
holographic shell prompt.
For reference, in Linux the driver atl1c is working for it just fine.
Linux's lspci -vvv seems to git a lot more info, here it is:

Thanks.
>How-To-Repeat:
Use the alc driver after Aug. 30 2010, Dell N7010 laptop, Attansic/Atheros
device 2060 (rev c1) wired network card.
and then run:
ifconfig alc0 192.168.100.3
(or any other IP) or
dhclient alc0
