FreeBSD freebsd 13.0-RELEASE

手动编译igc驱动，并添加到系统

1.下载源码

freebsd/freebsd-src: FreeBSD src tree (read-only mirror) (github.com)

2.格式化一个FAT32格式的U盘

3.将下载好的igc驱动代码放入U盘

1
2
/usr/src/dev/igc
/usr/src/modules/igc

4.挂载U盘到系统

FreeBSD会将USB挂载为SCSI设备，在/dev目录可查看,这里U盘名为da0
查看U盘信息	gpart show da0
查看U盘格式	fstyp da0p1，这里是msdosfs
新建文件夹	mkdir /mnt/usb
挂载U盘到文件夹	mout_msdosfs /dev/da0p1 /mnt/usb

5.将驱动文件复制到源码目录

1
2
cp -rf /mnt/usb/dev/igc /usr/src/dev/igc
cp -rf /mnt/usb/modules/igc /usr/src/dev/igc

6.编译驱动

cd /usr/src/sys/modules/igc
编译
make
搜索生成的驱动文件
find / -name if_igc.ko
将if_igc.ko复制到安装目录
/boot/modules/if_igc.ko
加载驱动
kldload if_igc (重启失效)

7.配置网络

让系统自动加载
ee /boot/loader.conf
if_igc_load="YES"
配置连接方式
ee /etc/rc.conf
ifconfig_igc0="DHCP"

8.完成
