Here is the proposed revision to the bridge utilities interface to the kernel. The driving force is that the existing interface can't easily be converted to 32/64 bit compat. Right now, the bridge-utils (brctl) tries to handle 32bit command on 64 bit kernel, but the code is limited to sparc and wrong. Here is what I am thinking. get version - not needed? get bridges - /sys/class/bridge/* add bridge - SIOCBR_ADD_BRIDGE del bridge - SIOCBR_DEL_BRIDGE add if - SIOCBR_ADD_IF delete if - SIOCBR_DEL_IF get bridge info - /sys/class/bridge/brX/ get port list - /sys/class/bridge/brX/ports/* set bridge forward delay - /sys/class/bridge/brX/forward_delay set bridge hello time - /sys/class/bridge/brX/hello_time set bridge max age - /sys/class/bridge/brX/max_age set ageing time - /sys/class/bridge/brX/ageing_time set gc interval - deprecated does nothing anymore set get port info - /sys/class/bridge/brX/ports/ethX/* set bridge stp state - /sys/class/bridge/brX/stp set bridge priority - /sys/class/bridge/brX/priority set port priority - /sys/class/bridge/brX/ports/ethX/priority set path cost - /sys/class/bridge/brX/ports/ethX/cost get fdb entries - /proc/net/bridge/brX Other alternatives: - Use just ioctl's - Use just /proc (ugh) or sysctl's (double ugh) I expect that for 2.6 the kernel will accept (but warn) the old ioctl interface. The new utility will not generate the old ioctl's it would only work with new interface...
