Hi, I need some advice on coding a kernel module which acts as a wrapper to a network device driver. This new module sit's on top of a device driver and intercepts all incoming packets. The module has a function, say "myTx()", which intercepts the packet, and after mangling the packet, add's it a queue "myQ". Another function does the actual "delivery" of the packet to the network driver, let's say this is "myDeliver()". On receiving the first packet, myTx() has to add it to myQ, check if myDeliver() is "awake/active", if NOT, wake it up and return. Once myDeliver() is woken up, it iteratively delivers the packet to the actual driver until myQ is empty, and once done, it has to "sleep". Again at a later point, when myTx() has packet(s) to deliver, the above procedure repeats. I wanted to know what might be the best way of performing the wakeup and sleep procedure, for the myDeliver() function. Intial investigation revealed a few possible ways..., wait_queues? tasklets? timers (which can be expired immediately)? etc., but nothing seemed like an obvious choice. I am short of any expertise/experience here, any help would be much appreciated. Regards, - CCK./ -- Chandrakanth Chereddi. Elec. & Comp.
