USB2: [was: umass not detected correctly, axe not transmitting] AXE problems

[Hiroharu Tamaru]

Hi, I'm back with the results.
And to make it short, everything works now.
Thank you, Hans and Pyun, and all others who looked into this for me.

Some notes inline:

OK, the patch usb2_ethernet.patch2 in
<20090212043033.GC6313 at michelle.cdnetworks.co.kr> worked, and now the
ue0/AXE interface is working fine.

Though I have only tested in 100BaseTX/full-duplex mode,
ping -f over a 100Mbps switch run without any packet loss
(sysctl net.inet.icmp.icmplim=0, of course), and the interface
statics shows no errors too:

Name    Mtu Network       Address              Ipkts Ierrs    Opkts Oerrs  Coll
ue0    1500 <Link#4>      00:90:cc:xx:xx:xx    32634     0    32192    0     0
ue0    1500 192.168.1.0   192.168.1.3          32553     -    32190    -     -

This symptom was solved after I have brought my userland in
sync with the kernel.

So here I am, with all my USB2 problems solved!
Thank you all for this quick assistance!

And finally, I'd appreciate if you could send me or the list
the 'commit done' message on this ethernet patch and the
mountroot delay patch, so that I can mark to forget about
patching the kernel as I cvsup it.  Thanks.
