net/mlx5e: Poll event queue upon TX timeout before performing full channels recovery Up until this patch, on every TX timeout we would try to do channels recovery. However, in case of a lost interrupt for an EQ, the channel associated to it cannot be recovered if reopened as it would never get another interrupt on sent/received traffic, and eventually ends up with another TX timeout (Restarting the EQ is not part of channel recovery). This patch adds a mechanism for explicitly polling EQ in case of a TX timeout in order to recover from a lost interrupt. If this is not the case (no pending EQEs), perform a channels full recovery as usual. Once a lost EQE is recovered, it triggers the NAPI to run and handle all pending completions. This will free some budget in the bql (via calling netdev_tx_completed_queue) or by clearing pending TXWQEs and waking up the queue. One of the above actions will move the queue to be ready for transmit again.
