Stefano Brivio 64a0ba3b27 udp: Introduce recvmmsg()/sendmmsg(), zero-copy path from socket
Packets are received directly onto pre-cooked, static buffers
for IPv4 (with partial checksum pre-calculation) and IPv6 frames,
with pre-filled Ethernet addresses and, partially, IP headers,
and sent out from the same buffers with sendmmsg(), for both
passt and pasta (non-local traffic only) modes.
