Hello guys, I am getting out-of-order because a standalone ACK message is going sooner than ack messages with data, is it matter? or in receiver transport layer this ack message with len=0 does not affect the data stream order

Any decent implementation should be fine with this.

However in my exerience if you note that smaller packets arrive much sooner then larger packets (on the millisecond scale) then you have a serious bandwidth issue and you see other ackward things happening. If it only matters on the nano second scale then I expect no issues.
