Orange pi one plug network cable after booted , network will not active

[阿金]

In /head/sys/arm/allwinner/if_awg.c
awg_reset function

I comment this line,then when I power on board ,kernel loaded .
after that, I plug network cable ,this time I can ping network normally.

/* Soft reset all registers and logic */
// WR4(sc, EMAC_BASIC_CTL_1, BASIC_CTL_SOFT_RST);
