[PATCH 0/8] Don't use additional sockets for receiving "spliced" UDP communications

[David Gibson <david@gibson.dropbear.id.au>]

At present, the UDP "splice" and "tap" paths are quite separate.  We
have separate sockets to receive packets bound for the tap and splice
paths.  This leads to some code duplication, and extra open sockets.

This series partially unifies the two paths, allowing us to use a
single (host side) socket, bound to 0.0.0.0 or :: to receive packets
for both cases.

This is based on my earlier series with some fixes for the tap path.

David Gibson (8):
  udp: Move sending pasta tap frames to the end of udp_sock_handler()
  udp: Split sending to passt tap interface into separate function
  udp: Split receive from preparation and send in udp_sock_handler()
  udp: Receive multiple datagrams at once on the pasta sock->tap path
  udp: Pre-populate msg_names with local address
  udp: Unify udp_sock_handler_splice() with udp_sock_handler()
  udp: Decide whether to "splice" per datagram rather than per socket
  udp: Don't use separate sockets to listen for spliced packets
