brctl setportprio fails silently

[ecip]

Hi, when I issue a brctl setportprio command specifying priorities highen than 63 the command fails silently, thus the priority of the port is not changed:

brctl setportprio BRVAL VALSEV 32768

it gives no output and the priority is not changed. If we analyze the command using strace:

 strace brctl setportprio BRVAL VALSEV 32768
execve("/usr/sbin/brctl", ["brctl", "setportprio", "BRVAL", "VALSEV", "32768"], [/* 17 vars */]) = 0

Thank you for taking the time to report this bug and helping to make Ubuntu better.

This bug is marked as fixed in the Debian bug you linked, in version 1.5-1. Ubuntu will have carried this change since Oneiric, in version 1.5-2ubuntu1. Thus this bug is already fixed in the current development release, so I'm marking it as Fix Released.

I don't think that this is a high-impact bug and thus does not warrant fixing in any previous stable release (see https://wiki.ubuntu.com/StableReleaseUpdates#When).
