[LEDE-DEV] MT7621 support Jumbo frames

[Jaap Buurman]

I am able to test this on my DIR-860l. I could try to compile my own
build to test this, but I am no C programmer myself. Am I correct in
the following post about how to set the flag to allow for jumbo frames
to be set?: https://forum.lede-project.org/t/build-for-the-d-link-dir-860l/948/40?u=mushoz
If so, I will be able to apply the patch myself and test it. I could
then send a PR if the tests are successful.

Yours sincerely,

Jaap Buurman
