Subject: [PATCH] net: ethernet: mtk_eth_soc: do not enable page pool stats by
default
There is no reason for it to be enabled by default.
Align mtk_eth_soc driver to mt76 driver.
This option incurs additional CPU cost in allocation and recycle paths
and additional memory cost to store the statistics.
