Subject: swconfig: cleanup of kernel drivers and interface - add some comments to a few data... 
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bd6324190fb4784a51ae70ecd0b1e0c606213702;p=openwrt%2Fstaging%2Faparcar.git

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
