Hi,
While working with IrNET, I came across one problems that would require some changes minor to the ppp_generic kernel code. I will describe this feature and then we can start to flame each other or discuss how to implement them.
IrNET is PPP over an IrDA socket. A good analogy would be PPP over TCP/IP. If you thing in those terms, you will get the proper context. IrNET is a PPP driver hooking directly in ppp_generic.
Tx queue length --------------- Problem : IrDA does its buffering (IrTTP is a sliding window protocol). PPP does its buffering (1 packet in ppp_generic + dev->tx_queue_len = 3). End result : a large number of packets queued for transmissions, which result in some network performance issues.
Solution : could we allow the PPP channel to overwrite dev->tx_queue_len ? This is similar to the channel beeing able to set the MTUs and other parameters...
Have fun...
