XDP support is an increasing trend on the network devices. XDP main goal is
processing packets at the lowest point in the software stack avoiding
overheads. Memory recycling of received buffers achieved through
the in kernel pagepool API plays a fundamental role in the increased performance.
Adding XDP support on a driver can be non-trivial. In this talk we'll demonstrate
how porting a standard ethernet driver (mvneta/netsec) to XDP and the pagepool API can
boost performance.
Part of the page_pool evolution involves adding the recycling support
in the kernel's SKB stack and leverage the increased performance
attributes of the API.
