Since the patch had lots of code not related with 88E8062 dual port
controller, would you try attached patch again? I think the attached
patch is minimal one that makes 88E8062 work.
The patch also try to enable MSI for dual port controllers. At the
time of writing support for MSI I had no testers to experiment MSI so
MSI on dual port controllers were ignored. Please see if msk(4) take
advantage of MSI. irq256 or higher number would be showed in "vmstat
-i" output if MSI is active.
# vmstat -i
interrupt total rate
irq14: ata0 1450 1
irq16: fxp0 uhci0 2058 1
cpu0: timer 2705189 1999
irq256: mskc0 92 0
cpu1: timer 2704883 1999
Total 5413672 4001
I guess MSI is enabled.
As of the results of tests I'm not sure what to start with... Initially
both interfaces seemed non-functional with nothing getting transmitted
to other machine. Then I noticed that it seems that msk1 seemed to
receive packets that should be on msk0 (?):
# tcpdump -i msk1
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on msk1, link-type EN10MB (Ethernet), capture size 96 bytes
20:28:41.757722 arp who-has 192.168.0.1 tell 192.168.0.2
192.168.0.2 is on em0 on other machine, and should be on the same switch
as msk0. At least this was the case on previous tests in which both
interfaces worked...
Another time on the same test corrupted data was received:
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on msk1, link-type EN10MB (Ethernet), capture size 96 bytes
20:31:29.806041 d3:04:ff:ff:ff:ff (oui Unknown) > 22:a0:00:00:02:f0 (oui
Unknown), ethertype Unknown (0x3cc0), length 60:
0x0000: de07 0000 0000 0000 0000 0000 0000 0000 ................
0x0010: 0000 ffff ffff ffff 0002 0406 0800 0806 ................
0x0020: 0001 0800 0604 0001 0002 0406 0800 ..............
And later magically the msk1 <-> em0 link started working... Seems to
work just fine after reboot (I didn't try to power down machine, just
shutdown -r).
So to sum up - in the end mks1 interface worked in some weird way - but
it seemed to represent the link that was under msk0 previously.
