Re: Can support at Linux LXC?

[Oliver Hartkopp <socketcan@hartkopp.net>]

Hi Dererk,

just looked for more LXC information.

The Linux CAN subsystem is currently not aware of net namespaces.

We already had some discussions about it:
http://marc.info/?l=linux-can&w=2&r=1&s=namespace&q=b

but it did not get further from the last posting of Andri Yngvason as we all
seem not to be the name space specialists.

Regards,
Oliver
