Description Jan Steffens 2014-08-15 23:35:05 UTC

Starting with iproute2 3.16.0, "ip link add br0 type bridge" does not work anymore, returning "Error: argument "br0" is wrong: Unknown device". However, "ip link add name br0 type bridge" still works.

Bisection led to 9a02651 (ip: check for missing dev arg when doing VF rate) as the first bad commit.

Kernel 3.16.1, x86_64

Bisecting the kernel or the iproute tool ?

Comment 2 Jan Steffens 2014-08-21 16:02:18 UTC

The iproute tool.

Comment 3 Evangelos Foutras 2014-09-20 14:35:48 UTC

I believe this was fixed earlier this month:

Comment 4 Jan Steffens 2016-12-21 18:19:05 UTC

Should be fixed since v3.17.0.
