Hi All, I am a newbie in RTNET and i have questions. I have to program a specific MAC protocol for interacting, over an ethernet bus, with hardware specific distributed units that implement this protocol. Since these units just have a MAC and an Application Layers, i have to reproduce this network stack on the PC side, that's why i don't want to use any IP layer on top of my MAC layer. The MAC Layer will be included in a real-time task running in kernel space (mandatory in the control architecture i am developing).
To do the job, i have to deal with Ethernet packet capturing and sending, in addition of IRQ handling. What i need is a kind of HAL that provide me an abstraction of Ethernet drivers and a library that provides me all necessary functions (IRQ handling, packet capturing and sending). In fact, what I need is something quite like the well-known libpcap library. Optimally, I search for a way to "easily" plug RTnet low-level layer with libpcap library. So my questions are : - Can i use libpacap directly in kernel mode ? - If no, can i use, by any way, libpcap in hard real-time RTAI tasks in combination with RTNET ? If yes, How should i proceed ? - If no, does RTnet provide functions like the ones provided by libpcap ? If yes, where could I find documentation/examples on these functions ?
