New plan! I will write a kernel module to filter pacets from assoziated
stations. Since 2.4 it is possible to register netfilter hooks. With
help of this, a callback function can decide which packet will be droped
or passed. This module will have a misc device. Over ipctrls you can
configure it (like you did it in hostap driver). I will borrow some
code of hostap driver ;)
