[jensdrenhaus]

The goal:
Implement netstat for u-root with the most features of net-tools/netstat

Features of netstat:

• List tcp, udp, raw IPv4 and IPv6 sockets and unix sockets
• Print routing tables for IPv4 and IPv6
• List multicast group memberships of network interfaces for IPv4 and IPv6
• Print network interface information for all interface
• Print network interface information for a specific interface
• Print network statistics for IPv4 and IPv6

netstat usage:

netstat [-vWeenNcCF] [<Af>] -r         netstat {-V|--version|-h|--help}
netstat [-vWnNcaeol] [<Socket> ...]
netstat { [-vWeenNac] -I[<Iface>] | [-veenNac] -i | [-cnNe] -M | -s [-6tuw] } [delay]

<Socket>={-t|--tcp} {-u|--udp} {-U|--udplite} {-S|--sctp} {-w|--raw}
           {-x|--unix} --ax25 --ipx --netrom
<AF>=Use '-6|-4' or '-A <af>' or '--<af>'; default: inet
