net: calxedaxgmac: fix race between xgmac_tx_complete and xgmac_tx_err

Browse source

It is possible for the xgmac_tx_complete to run concurrently with
xgmac_tx_err since there are no locks. Fix this by moving the tx
error handling to a workqueue so we can disable napi while we reset
the transmitter.
