Changes to add /sys/class/net nodes

Trying to install Minecraft using https://gameservermanagers.com/ in a Linux jail, the software expects data in /sys/class/net which at the moment is not implemented.(https://dongqixue.blogspot.com/2017/05/linux-kernel-documentation-for.html).
I just implemented the nodes that the application requires.
Now the application fails because it needs a NETLINK emulation which also does not exists on current linuxlator.
I have attached changes to linsysfs to add the needed nodes for /sys/class/net

It appears you've attached a copy of a modified linsysfs.c, not a patch. Please attach a patch instead (e.g., from diff -u), or create an account on our Phabricator instance and upload the patch there (following the instructions on https://wiki.freebsd.org/Phabricator)
