SubjectProblem with 3c905B nic
Date
Hi,

I have a NFS client which was connected to the server directly
by crossover cable. 100mbit Enternet was working as expected
(~10mbytes/sec peak). Recently I had to move to different
location and now I'm connected to the same server through
stack of four HP ProCurve 4000M switches.
Now I'm getting ~2mbytes/sec peak.

My NIC is 3c905B, seems to working fine under Win NT in 100mbit
full-duplex mode.

Since I boot from network I have NIC drivers compiled in,
tried to instruct 3c59x.c to be more verbose with
ether=0,0,0x8200,eth0 with no success... why?

I put debug printk in the source, it does not print:
if (dev->mem_start) {
/*
* The 'options' param is passed in as the third arg to the
* LILO 'ether=' argument for non-modular use
*/
option = dev->mem_start;
===> printk(KERN_DEBUG "VDA: ether=xx,xx,0x%08x,xxx\n",dev->mem_start);
}
Ok, I have recompiled drivers/net/3c59x.c with vortex_debug=4
set manually and now I see I'm having problems.

Do someone know what's up here?
