The Linux network stack does not lack for features; it also performs well enough for most uses. At the highest network speeds, though, any overhead at all is too much; that has driven the most demanding users toward specialized, user-space networking implementations that can outperform the kernel for highly constrained tasks. The express data path (XDP) development effort is an attempt to win those users back, with some apparent success so far. With the posting of the AF_XDP patch set by Björn Töpel, another piece of the XDP puzzle is coming into focus.
