Subject: [9front] 7th gen Intel NUC ethernet troubles
Reply-To: 9front@9front.org
Precedence: bulk

I am trying to test 9front on a 7th gen Intel NUC which has an I219-V
ethernet card. I'm unskilled administrating Plan 9, but I did test the
process on a Raspberry Pi to confirm that I was able to get the
network working and I'm probably not just holding it wrong.

ip/config fails with "dhcprecv: read timed out", after which
/net/ether0/stats shows:
in: 0
link: 0
out: 7
crc errs: 0
overflows: 0
soft overflows: 0
framing errs: 0
buffer errs: 0
output errs: 0
prom: 0
mbps: 1000
addr: f44d306ee4a1

/dev/kmesg has this to say:
#l0: i219: 1000Mbps port 0xDC300000 irq 11 ea f44d306ee4a1
[...]
i219: phy 1 wedged 08210000
i219: phy 2 wedged 08410000
i219: no phy

pci -v gives:
0.21.6: net 02.00.00 8086/15d8 11 0:dc300000 131072
    Intel Corporation Ethernet Connection (4) I219-V

Any tips on what I can try next? Has anyone had success with this
device, or is it a lost cause for someone without network driver
hacking knowledge?
