2023-09-20net: ethernet: amd: Convert to platform remove callback returning voidUwe Kleine-König3-12/+6
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert these drivers from always returning zero in the remove callback to the void returning variant.

2023-09-18net: stmmac: Tx coe sw fallbackRohan G Thomas2-0/+13
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.
