Fix large frames in the Gemini ethernet driver

This is the result of a bug hunt for a problem with the RTL8366RB DSA switch leading me wrong all over the place. I am indebted to Vladimir Oltean who as usual pointed out where the real problem was, many thanks! Tryig to actually use big ("jumbo") frames on this hardware uncovered the real bugs. Then I tested it on the DSA switch and it indeed fixes the issue.
