So what I'm looking for is an interface index (or name) but the real one.if_nametoindex(3) and ioctl(2) don't seem to help me here. Now the only way I found how to do this is via /sys. Let me demonstrate on example what I need:# cat /sys/class/net/bond0.1007/ifindex 26# cat /sys/class/net/bond0.1007/iflink23                                  <-- I need either this or a reference to bond0# cat /sys/class/net/bond0/ifindex 23Is there a way to do it with a function call or the only way is sysfs?Thanks
Is it possible to get network interface index not via /sys?
sysfs;network interface;ioctl
