linux 에서 추가 설치했던 lan driver 삭제

머, 정확히는 잘 모르겠지만,
기존에 쓰던 via-rhine lan card 가 장착된 pc
여기서 realtek lan card 를 하나 더 장착, 8139too 로 올라온다
근데 이넘이 드라이버는 다 올라온거 같은데, rx 쪽이 전부 error 로 떨어진다
shutdown 하고, realtek 빼고, 다른 realtek 장착

lsmod | grep 8139 하니, 8139too, 8139cp 요렇게 2개 보인다

ifconfig 하면 기존 via card 만 보인다

그래서 기존 꺼 삭제 rmmod -f 8139too

[root@localhost network-scripts]# lspci | grep -i Ethernet

00:12.0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 78)

이제 2개가 보이는데, ifconfig 하면 eth1은 없고, eth2 가 생겼다

rm /etc/udev/rules.d/70-persistent-net.rules

reboot 후 다시 정리되서 eth0, eth1 이 보이고, 설정데로 ping 도 응답하기 시작 했다

아래의 부팅 후 dmesg
