Subject: Odd ethnetnet problem
Date: Thu, 5 Aug 1999 23:53:42 -0500 (CDT) [thread overview]
Message-ID: <19990806045342.6946.qmail@kunk.jriver.com> (raw)
I have an iMac with the usual builtin bmac ethernet controller. It is on a
10 mb hup with a couple of other boxes (one professional svr4 and one linux
2.2.10 on intel)
The hub is a generic dumb 10mb half duplex only unit. The problem is this,
When the iMac talked to either Unix box from MACOS, I would get
nearly 100% of the bandwidth of the ethernet on put's and get's.
When the iMac talked to either Unix box from linux-ppc (several kernels
tested), I would get nearly 100 percent on receive but REALLY slow
response on transmit (like about 40k/sec). Watching the lights on the hub,
it appears that there is a really big delay restarting transmit after
a collision occurs. Perhaps duplex set wrong?
Since it works fine in MACOS, I looked over the linux driver and didn't see
anything obviously wrong. Has anyone else run into this before?
Bob
