[PATCH net 06/13] rxrpc: Fix loss of PING RESPONSE ACK production due to PING ACKs

Separate the output of PING ACKs from the output of other sorts of ACK so that if we receive a PING ACK and schedule transmission of a PING RESPONSE ACK, the response doesn't get cancelled by a PING ACK we happen to be scheduling transmission of at the same time. If a PING RESPONSE gets lost, the

[PATCH net 05/13] rxrpc: Fix warning by splitting rxrpc_send_call_packet()

Split rxrpc_send_data_packet() to separate ACK generation (which is more complicated) from ABORT generation. This simplifies the code a bit and fixes the following warning: In file included from ../net/rxrpc/output.c:20:0: net/rxrpc/output.c: In function 'rxrpc_send_call_packet': net/rxrpc/ar-int

Don't request an ACK on the last DATA packet of a call's Tx phase as for a client there will be a reply packet or some sort of ACK to shift phase. If the ACK is requested, OpenAFS sends a REQUESTED-ACK ACK with soft-ACKs in it and doesn't follow up with a hard-ACK. If we don't set the flag, OpenA
