net/linux: use NETLINK_SOCK_DIAG
Browse files Browse the repository at this point in the history 
To retrieve network information use NETLINK_SOCK_DIAG instead of walking
/proc/<PID> and parsing files.
Consequently this reduces the number of syscalls, as walking /proc/<PID> and
opening, reading and closing files is no longer required. But it also reduces
the memory footprint as reading files into memory for processing is no longer
required.

Supersedes #809
