Any further comments?

Notable difference from some other drivers --
netdev_tx_reset_queue(txq) is called for all queues in
bcmgenet_netif_start(), just before netif_tx_start_all_queues(dev).
This is to ensure that BQL is reset before the interface becomes
operational.

I think that is the right place for these calls.

Some other drivers call it from the "interface down" path.
