My wallstreet/300 has a similar, possibly related problem.  any FTP transfer
originating from my powerbook in Linux (under any client or server) has a max
transfer under 100k.  This is a BMAC driver problem.  my brother's lombard
(BMAC+) seems to have no problem.  The big thing to notice is that in my case,
the traffic is colliding... with itself.  Duplex problem? (BMAC+ can, BMAC
cant).. but since we're not on a switched hub, that doesn't make much sense.

MacOS has no problems with my ethernet card; incoming FTP transfers work normal;
and i double checked with an FTP to myself (using lo), and it went fast.  So i
deduce this is a problem in someway connected to the hardware driver.

I have tested one theory.  In bmac.c, there is a delay called MIFDELAY that in
2.2.1 was 500, and now is 10.  I tried putting it back to make sure it wasn't
tripping on itself with that, but there was no improvement.

Other ideas?

Same problem for me. Incoming traffic is fast and reliable,  outgoing
data  is  slow  (usually  around  80  k/s)  and large transfers often
contain garbage (bad data, but I cannot see any errors reported).

Same here.
