This potentially saves a little space and makes it easier to alter the header just before transmission (the flags may get altered and the serial number has to be changed). (2) Mask off the Tx buffer annotations and add a flag to record which ones have already been resent. (3) Track RTT on a per-peer basis for use in future changes. Tracepoints are added to log this. (4) Send PING ACKs in response to incoming calls to elicit a PING-RESPONSE ACK from which RTT data can be calculated. The response also carries other useful information. (5) Expedite PING-RESPONSE ACK generation from sendmsg. If we're actively using sendmsg, this allows us, under some circumstances, to avoid having to rely on the background work item to run to generate this ACK. This requires ktime_sub_ms() to be added. (6) Set the REQUEST-ACK flag on some DATA packets to elicit ACK-REQUESTED ACKs from which RTT data can be calculated. (7) Limit the use of pings and ACK requests for RTT determination. Changes: (V2) Don't use the C division operator for 64-bit division. One instance should use do_div() and the other should be using nsecs_to_jiffies(). The last two patches got transposed, leading to an undefined symbol in one of them. Reported-by: kbuild test robot <lkp@intel.com> ==================== Signed-off-by: David S.
