This patch adds bcmgenet_tx_poll for the tx_rings. This can reduce the interrupt load and send xmit in network stack on time. This also separated for the completion of tx_ring16 from bcmgenet_poll. The bcmgenet_tx_reclaim of tx_ring[{0,1,2,3}] operative by an interrupt is to be not more than a certain number TxBDs. It is caused by too slowly reclaiming the transmitted skb. Therefore, performance degradation of xmit after 605ad7f ("tcp: refine TSO autosizing"). Signed-off-by: Jaedon Shin <redacted> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>Applied.
