使用如下脚本可以获取到SR-IOV中，Physical Functions和Virtual Functions之间，清晰的关系。
包括接口名称，domain、bus、slot、function的编号信息，接口mac地址信息，以及给VF是否被绑给了vm。
#!/bin/bash
function pf_vf(){echo "<=============>PF:$1<=============="echo "`lspci|grep $(ls -l /sys/class/net/$1/ |grep device |cut -d '/' -f 4|sed 's/0000://g')` --> $1"echo " VF:"eth_dev=`ls /sys/class/net/$1/device/virtfn* -l | cut -d ">" -f 2 |cut -d "/" -f 2`for i in $eth_dev; do vf_name=`ls /sys/bus/pci/devices/$i/net 2>&1`;if [ $? -eq 0 ]; thenecho " |_ `lspci|grep $(echo $i|sed 's/0000://g')` --> $vf_name"; echo " |_ _ $(ip link show |grep -w $vf_name -A1 |grep -v $vf_name|awk '{print $2}')";elseecho "$i has bound by vm !"fidone
}
for i in $(ip link show |grep mq|cut -d ':' -f 2);do pf_vf $i;done
脚本执行效果如下：
