sfc: configure UDP tunnel offload ports
Implement ndo_udp_tunnel_{add,del} to update the NIC's list of VXLAN and GENEVE UDP ports. Also reset the port list to empty on driver load and on driver unload, with appropriate flag set on the unload case. These port numbers are used for RX inner checksum offload, and in future will also be used for TX inner checksum offload and encapsulated TSO.

issue, we want to implement refcounting for chan_busy array that contains the active dma transfers. Increasing the autosuspend delay won't help as that the delay could be potentially seconds, and it's best to let the USB subsystem to deal with the timeouts on errors. The earlier attempt for runtime PM was buggy as the pm_runtime_get/put() calls could get unpaired easily as they did not follow the state of the chan_busy array as described in commit 098de42ad670 ("dmaengine: cppi41: Fix unpaired pm runtime when only a USB hub is connected". Let's fix the issue by adding pm_runtime_get() to where a new transfer is added to the chan_busy array, and calls to pm_runtime_put() where chan_busy array entry is cleared. This prevents any autosuspend timeouts from happening while dma transfers are active.
