not nice.
this is what I see:
...
dwc0: <Amlogic Meson Gigabit Ethernet Controller> mem 0xc9410000-0xc9411fff irq 10017 on simplebus0
miibus0: <MII bus> on dwc0
rgephy0: <RTL8169S/8110S/8211 1000BASE-T media interface> PHY 0 on miibus0
rgephy0: OUI 0x00e04c, model 0x0011, rev. 6
000baseT-FDX-master, auto
random: harvesting attach, 8 bytes (4 bits) from rgephy0
rgephy1: <RTL8169S/8110S/8211 1000BASE-T media interface> PHY 1 on miibus0
rgephy1: OUI 0x00e04c, model 0x0011, rev. 6
000baseT-FDX-master, auto
random: harvesting attach, 8 bytes (4 bits) from rgephy1
random: harvesting attach, 8 bytes (4 bits) from miibus0
dwc0: bpf attached
dwc0: Ethernet address: 62:73:64:b7:54:2e
..

also, I think that the fact that kenv(1) does not show anything
means there is something else fishy.
