gnl2go: Generic NetLink in Go

About:

This is go based lib to work with generic netlink socket's. The lib was writen under heave influenc of FB's gnlpy (so all kudos goes to FB's team and all the blame to me)

in gnl2go.go you can find generic routines to work with gnetlink

in ipvs.go: lib to work with IPVS

in example/: few commands, which shows how to work with ipvs's lib

####TODOs: bugfixes etc (i do know about incorrect ipv6struct to ipv6string conversion) i dont use it (lib for ipvs) in production yet. not sure when i would. prob till that time i'd only fix problem with ipv6 to string and any other minor bugs, which i'd bump into

####Output from example in example/:

sudo ipvsadm -ln
