Linus Walleij 0b480c654e net: ethernet: cortina: Fix MTU max setting ... [ Upstream commit dc6c0bfbaa947dd7976e30e8c29b10c868b6fa42 ] The RX max frame size is over 10000 for the Gemini ethernet, but the TX max frame size is actually just 2047 (0x7ff after checking the datasheet). Reflect this in what we offer to Linux, cap the MTU at the TX max frame minus ethernet headers. We delete the code disabling the hardware checksum for large MTUs as netdev->mtu can no longer be larger than netdev->max_mtu meaning the if()-clause in gmac_fix_features() is never true.
