rxrpc: Only transmit one ACK per jumbo packet received
[ Upstream commit 012b7206918dcc5a4dcf1432b3e643114c95957e ]
Only generate one ACK packet for all the subpackets in a jumbo packet. If
we would like to generate more than one ACK, we prioritise them base on
their reason code, in the order, highest first:
OutOfSeq > NoSpace > ExceedsWin > Duplicate > Requested > Delay > Idle
For the first four, we reference the lowest offending subpacket; for the
last three, the highest.
This reduces the number of ACKs we end up transmitting to one per UDP
packet transmitted to reduce network loading and packet parsing.
