开启后ifconfig对应的网卡参数变为
en6: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
options=404<VLAN_MTU,CHANNEL_IO>
ether 00:e0:4c:68:01:65
nd6 options=201<PERFORMNUD,DAD>
media: autoselect (2500Base-T <full-duplex>)
status: active
如果在开启后再插入这张网卡，则无法获取到DHCP，也获取不到ipv6
en6: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
options=404<VLAN_MTU,CHANNEL_IO>
ether 00:e0:4c:68:01:65
inet6 fe80::82:ff69:e1c5:7b16%en6 prefixlen 64 secured scopeid 0x8
inet 169.254.228.104 netmask 0xffff0000 broadcast 169.254.255.255
nd6 options=201<PERFORMNUD,DAD>
media: autoselect (2500Base-T <full-duplex>)
status: active
即使禁用所有内置网卡，只使用这张网卡的情况下开启增强模式也一样，surge会直接提示没有网络
网卡芯片为RTL8156b,打算用来替代掉mac mini m4的内置网卡
