2023-09-18net: stmmac: Tx coe sw fallbackRohan G Thomas
Add sw fallback of tx checksum calculation for those tx queues that don't support tx checksum offloading. DW xGMAC IP can be synthesized such that it can support tx checksum offloading only for a few initial tx queues. Also as Serge pointed out, for the DW QoS IP, tx coe can be individually configured for each tx queue. So when tx coe is enabled, for any tx queue that doesn't support tx coe with 'coe-unsupported' flag set will have a sw fallback happen in the driver for tx checksum calculation when any packets to be transmitted on these tx queues.
