Hi! We see large (4-8x) increase of what looks like TCP RTOs after rising the Tx coalescing above Rx coalescing timeout.
Quick tracing of the events seems to indicate that the data has already been acked when we enter tcp:tcp_retransmit_skb: sk_state: 1 icsk_ca_state: 4 bytes_in: 0 bytes_out: 742 bytes_acked: 742 Is this a known condition? Is the recommendation to filter such events out in tracing infra?
