Well things aren't looking so good for the sk(4) driver on the ES40
either.  We managed to source a D-Link Systems DGE-530T card to test as
well, and it is at least recognized:

[console]<@> # dmesg | fgrep -e skc0 -e makphy0
skc0 at pci1 dev 1 function 0: dec 6600 irq 24
skc0: DGE-530T Gigabit Ethernet Adapter rev. (0x1)
sk0 at skc0 port A: Ethernet address 00:0f:3d:88:13:3d
makphy0 at sk0 phy 0: Marvell 88E1011 Gigabit PHY, rev. 3
makphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto



I didn't know which wire they'd plugged into it so of course I picked
the wrong subnet first or at least that's what I thought given what I
initially observed

[console]<@> # ifconfig sk0 inet 10.10.10.2/24 up
[console]<@> # ping 10.10.10.1
PING 10.10.10.1 (10.10.10.1): 48 data bytes
ping: sendto: Host is down
ping: sendto: Host is down
^C
----10.10.10.1 PING Statistics----
13 packets transmitted, 0 packets received, 100.0% packet loss



But then when I tried to change the address it barfed completely:

[console]<@> # ifconfig sk0 10.10.10.2 delete     
[console]<@> # ifconfig sk0 inet 10.20.20.2/24 up
sk0: failed alloc of 0th mbuf
sk0: initialization failed: no memory for rx buffers
sk0: failed alloc of 0th mbuf

[console]<@> # ifconfig sk0       
sk0: flags=8803<UP,BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        address: 00:0f:3d:88:13:3d
        media: Ethernet autoselect (1000baseT full-duplex)
        status: active
[console]<@> # ifconfig sk0 inet 10.20.20.2/24 up
sk0: failed alloc of 0th mbuf
sk0: initialization failed: no memory for rx buffers

[console]<@> # 


Turns out I was right about which subnet it was on in the first place.
The card can receive packets OK, at least in promiscuous mode, but it
never transmits anything that I can see at the test host on the other
side of the switch.


[console]<@> # tcpdump -vvv -n -e -i sk0

The counters do seem to claim that one packet was transmitted:

Perhaps it's still sitting in a buffer and not going anywhere....
