jumbo frames support on 10/100 eth card

[sengelma]

Hi !

Does anyone know if there is a way to received jumbo ethernet frames ( > 1500 bytes) with eth10/100 card -- such as Intel 82551IT ??

Operating at kernel level, I am able to successfuly send jumbo frames.
But I cannot receive such frames.

I guess if the driver can process those packets on the way out, it should be able to do, so on the way in... or am I wrong ??

Let me know if there is any work around ! Maybe modifying module driver e100 ?

I ll keep the post updated if I find something.

Cheers,

Samuel

I did some inverstigation
Unfortunately packet drop in e100 occurs because of an "hardware error" bit set to 1 by lower level (a.k.a the eth card) ; plus, the advertized size is wrong (max observed was 151. I am afraid it is not possible, by changing e100 source code, to receive jumbo frames
