While looking what other distros do I came across this patch:
https://pkgs.fedoraproject.org/cgit/bridge-utils.git/tree/bridge-utils-1.5-check-error-returns-from-write-to-sysfs.patch

Beside of checking return errors is fixes also the sysfs path in br_set().
Can you please merge it upstream?

Distros seems to carry more patches for that package, if it helps I can do the patch hunting for you.
It would be nice to have a recent bridge-utils release. The last one is from 2011.

Thanks,
//richard
