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?
