In short, the entire path from origin to destination must be configured to support jumbo frames. If not, then the devices at various points in the path will attempt to scale and you'll end up getting fragmentation and higher overhead in the devices leading to worse overall performance.
Have you verified this is the case?
I believed so everything along the path supports the MTU size I was testing with. The test path is short, basically NIC -> Lan Cable -> HP 1910 -> Lan Cable -> NIC.
The switch is spec'd to support up to 9K jumbo frame, enabled by default based on a FAQ I found on 3Com/HP when trying to figure out where do I turn it on.
Of course, the quality of the driver for your NIC will also play a role.
This I have no idea which was why I was wondering about the elrepo driver.
