swconfig: cleanup of kernel drivers and interface
- add some comments to a few data structures - add a switch_dev_ops data structure for attributes and callback to replace the stupid template memcpy - get rid of the switch_dev.priv pointer - using container_of() is better git-svn-id: svn://svn.openwrt.org/openwrt/trunk@22476 3c298f89-4303-0410-b956-a3cf2f4a3e73
