packet : remove init_net restriction
The af_packet protocol is used by Perl to do ioctls as reported by
Stephane Riviere:
"Net::RawIP relies on SIOCGIFADDR et SIOCGIFHWADDR to get the IP and MAC
addresses of the network interface."
But in a new network namespace these ioctl fail because it is disabled for
a namespace different from the init_net_ns.
These two lines should not be there as af_inet and af_packet are
namespace aware since a long time now. I suppose we forget to remove these
lines because we sent the af_packet first, before af_inet was supported.
