Hi David,


yes, I used brctl addif/delif on an other terminal to modify the bridge.
I also tried to enslave my em1 interface (not only dummy0/dummy1). That
worked too.

Also, even I didn't say so, I got it right with using the correct
library version (by setting LD_LIBRARY_PATH, checked with ldd).

I tested the git version, commit
941ba950a9fa914e324c7e204c145bf7af526bf4 (libnl3_2_11). Compiled with

  git clean -fdx && ./autogen.sh && ./configure && make


It might be related to your kernel/architecture, although you say it
breaks also on your x86-64. I cannot reproduce any issues on my
3.13.9-200.fc20.x86_64 kernel.


Great if the newest version fixes it for you. It would be interesting
however to find the reason. If you care, I would suggest to git-bisect
it.


ciao,
Thomas
