The enetc driver does not implement .ndo_change_mtu, instead it configures the MAC register field PTC{Traffic Class}MSDUR[MAXSDU] statically to a large value during probe time. The driver used to configure only the max SDU for traffic class 0, and that was fine while the driver could only use traffic class 0. But with the introduction of mqprio, sending a large frame into any other TC than 0 is broken. This patch fixes that by replicating per traffic class the static configuration done in enetc_configure_port_mac().
