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

[阿金]

in if_awg.c awg_reset function
soft reset(EMAC_BASIC_CTL_1) will not be 0 till network cable plug .
(EMAC_BASIC_CTL_1 will remain 1 till network cable plug)

so this seem orange pi one hardware bug?,
could I fix this from software??
(In my test, I watch relative EMAC registers,seem not different when
network cable plug in or off)
