Checking source code of bridge-utils, there seems to be no code that lets one 
actually set this value, nor does it appear that the kernel ioctl interface 
allows for modifying gc_timer, (it appears to be a read-only field).

This must mean the documentation included in bridge-utils (specifically
in bridge-utils-interfaces manpage about including a bridge_gcint value
in /etc/network/interfaces to control this is incorrect.
