It has been reported [0] that using pause frames in jumbo mode impacts performance. There's no available chip documentation, but vendor drivers r8168 and r8125 don't advertise pause in jumbo mode. So let's do the same, according to Roman it fixes the issue.

This patch doesn't apply cleanly on some kernel versions, but the needed changes are trivial.

This is not the correct way to submit patches for inclusion in the stable kernel tree. Please read: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly.

Until recently the procedure in netdev has been to annotate the patch as "net" and not cc stable. IIRC there is an experiment to cc stable. If this isn't applicable any longer and the old process still applies, then please ignore the cc'ed stable.
You need to put the "Cc: stable..." in the signed-off-by area, as the documentation link above states.
