Hi, Michael!

By the way, the driver code is currently available at
http://sis4be.cvs.sourceforge.net/sis4be/usb_asix/. It inherits
skeleton functionality from Haiku's usb_ecm one and support ASIX
AX88172/AX88772/AX88178-based USB2Ethernet adapters. It is also
known as "if_axe" on FreeBSD and as "asix" on Linux. May it be
useful to beautify Haiku's Tree too? ;-)
Nice work! I would say there's no reason not to include it, so from my
perspective feel free to add it.
Thank you!
Unfortunately I still have some Haiku-specific problem with this driver.
The problem is following: - it stop receiving data from input USB pipe
about 1200 seconds after the connection was established. I check this
with sending pings to Haiku machine from outside and pinging my DSL
modem from this Haiku machine. In first case the usb_asix.log on this
machine traces only GET_LINK_STATE activity after the "1200 seconds
limit" goes away. At this time the driver is blocked on reading from
input pipe. In second case - the reading of input pipe is blocked too
but ping packets from this PC looks like successfully written into
output pipe - Write calls are logged and write callback is also handled
with B_OK status. It is very difficult to restore the connection after
this: neither re-plugging the adapter nor killing and restarting the
net_server helps in most cases. I have tried this situation with other
network devices: embedded rtl8139 and external USB ECM-compatible DSL
-modem. They work without such problem. Note that this is a Haiku-only
issue - BeOS R5/BONE works with this driver for a days under big load
without a problem. :-\
My "ideas box" is empty. :-( Frankly speaking I'm new in networking
area. Can somebody any ideas to try?
Thank you.
