Hi,

I am attempting to implement a circular buffer for the tx path of a
networking driver. From my understanding this is something that is
very common, yet I am struggling to find a clear way to do it.

Have you looked at include/linux/kfifo.h?

thanks Greg, I ended up using kfifo for the tx path and circ_buf for
the rx path.

Tobin.
