[PATCH iproute2 0/4] Switch network ns w/o execvp for iproute2 tools

[Vadim Kochan <vadim4j@gmail.com>]

This series adds new -n[etns] option to ip, tc & bridge tools which
allows to easy and faster switch to specified network namespace. So instead of:

    ip netns exec NETNS { ip | tc | bridge } OBJECT COMMAND

it will be possible do the same by:

    { ip | tc | bridge } -n[etns] NETNS OBJECT COMMAND

I skipped misc tools and will work on them later.

Vadim Kochan (4):
  lib: Add netns_switch func for change network namespace
  ip: Allow to easy change network namespace
  bridge: Allow to easy change network namespace
  tc: Allow to easy change network namespace
