Re: wireless network interfaces and network namespaces

[Kevin Wilson <wkevils@gmail.com>]

Thanks!
Running:
iw phy phy0 set netns 3433
indeed moved wlan0 to the network namespace I created, where process 3433 ran.
I did not see a way to specify the network namespace name for moving
wlan0 in this command (at least iw help does not show it and  I am
using iw 3.4-1 on ubuntu). I did not looked into the source code of iw
though.
