====================
rxrpc: Development

Here are some development patches for AF_RXRPC.  The most significant points
are:

 (1) Change the tracepoint that indicates a packet has been transmitted
     into one that indicates a packet is about to be transmitted.  Without
     this, the response tracepoint may occur first if the round trip is
     fast enough.

 (2) Sort out AFS address list handling to better enforce maximum capacity
     to use helper functions to fill them and to do an insertion sort to
     order them.  This is here to make (3) easier.

 (3) Keep AF_INET addresses as AF_INET addresses rather than converting
     them to AF_INET6 in both AF_RXRPC and kAFS.  I hadn't realised that a
     UDP6 socket would just call down into UDP4 if given an AF_INET
     address.

 (4) Allow the timestamp on the first DATA packet of a reply to be
     retrieved by a kernel service.  This will give the kAFS a more
     accurate base from which to calculate the callback promise expiration.

 (5) Allow the rxrpc protocol epoch value to be retrieved from an incoming
     call.  This will allow kAFS to determine if the fileserver restarted
     and if two addresses apparently assigned to the same fileserver
     actually are different boxes.
