Re: [cobalt-developers] Re: Replacing eepro100 with e100, need some .h source files

["William L. Thomson Jr." <wlt@xxxxxxxxxxxxxxxxxxxx>]

Tim,
	FYI, on a different machine I had three nics, one of which used the 
eepro100 mod. A guy from intel told me to replace the eepro100 with 
e100, and I could not tell a difference.It was not any better, nor was 
it worse. The only difference was my kernel loaded a single mod for all.

I have several machines now running e100, and have not had a problem. 
Even during backup transfers of upwards of a gig. I noticed a big 
difference when I grouped two nics together under a single IP using 
IANS. And any time I have two or more available Intel nics I use IANS.

Once again, I am not a kernel hacker, and have no clue of other 
experience with e100 other than my own. Which to date has been positive.

Also e100 provided some aditional features allowing me to dial it in 
further with a Cisco switch, like disabling IFS. So all my experiences 
to date have been positive. I imagine it will be the same with the 
Cobalt, except for the IP alias issue which I know I will run into.

I will post results either way.

Also, I have not fully looked into it, but when doing large transfer on 
the local lan from the RaQ does take time, and has a ton of collisions 
of the switch.

Without having looked into it myself, what is the setting of eepro100?

Is it set to auto detect duplex and speed? Or is it set to full duplex 
100mps? Which I am sure is the reason for the collision, because by 
default on the switch I force 100mps full duplex. Unless the device 
requires autodetect. So far I have not had to force any of the e100 to 
100mps full-duplex, not do I get large amounts or any collisions on them.

I am not blaming eepro100, I just do not think I have the switch dialed in properly.
