> This patchset contains fixes for 4 Errata topics from
> https://tools.ietf.org/html/draft-ietf-tsvwg-rfc4960-errata-01
> Namely, sections:
>  3.12. Order of Adjustments of partial_bytes_acked and cwnd
>  3.22. Increase of partial_bytes_acked in Congestion Avoidance
>  3.26. CWND Increase in Congestion Avoidance Phase
>  3.27. Refresh of cwnd and ssthresh after Idle Period
> 
> Tests performed with netperf using net namespaces, with drop rates at
> 0%, 0.5% and 1% by netem, IPv4 and IPv6, 10 runs for each combination.
> I couldn't spot differences on the stats. With and without these patches
> the results vary in a similar way in terms of throughput and
> retransmissions.
> 
> Tests with 20ms delay and 20ms delay + drops at 0.5% and 1% also had
> results in a similar way, no noticeable difference.
> 
> Looking at cwnd, it was possible to notice slightly lower values being
> used while still sustaining same throughput profile.

Series applied, thank you.
