[PATCH v2 0/5] Handle error events on UDP sockets

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

Add handling of the error queue for UDP sockets.  We certainly need
this for the flow table: this is the cause of the epoll loop that
Stefano noticed.  Even without the flow table it should improve
robustness and debugability.

Along the way we make a few other clean ups.

Changes from v1:
 * Assorted minor changes based on Stefano's review

David Gibson (5):
  conf: Don't configure port forwarding for a disabled protocol
  udp: Make udp_sock_recv static
  udp, tcp: Tweak handling of no_udp and no_tcp flags
  util: Add AF_UNSPEC support to sockaddr_ntop()
  udp: Handle errors on UDP sockets
