Oh, my apologies. I'm not subscribed to the list, so I mailed only to emails found on lkml web page with original top mail.

Thanks for the advice. I installed quilt on my system and applied your patchset to 2.6.26-rc6 kernel tree.

Ok, but in practice I need to reboot the system: 1) usually I compile into the kernel all code related to frequently used hardware. 2) This is a remote system, so reload of network module which is in use will be quite tricky.
I tested it with both jumbo frames disabled (no options), and enabled for 10k frames: ipg.jumbo=10k. It seems to work fine with all acceptable MTUs (max MTU == 10240).
