Subject: [2.6.7, e1000] large MTU allocation failure...
Date: Sat, 17 Jul 2004 13:04:09 +0200 (MEST) [thread overview]
Message-ID: <25348.1090062249@www11.gmx.net> (raw)
When I try to enable jumbo frames, and increase the MTU size to 9000 octets
[1], I see allocation failures in the kernel logs [2].
Is there another way of enabling jumbo frames and use a large MTU?
Kernel is stock 2.6.7, IA32.
