Merge branch 'dctcp'
Daniel Borkmann says:
====================
net: tcp: DCTCP congestion control algorithm
This patch series adds support for the DataCenter TCP (DCTCP) congestion
control algorithm. Please see individual patches for the details.
The last patch adds DCTCP as a congestion control module, and previous
ones add needed infrastructure to extend the congestion control framework.
Joint work between Florian Westphal, Daniel Borkmann and Glenn Judd.
v3 -> v2:
- No changes anywhere, just a resend as requested by Dave
- Added Stephen's ACK
v1 -> v2:
- Rebased to latest net-next
- Addressed Eric's feedback, thanks!
- Update stale comment wrt. DCTCP ECN usage
- Don't call INET_ECN_xmit for every packet
- Add dctcp ss/inetdiag support to expose internal stats to userspace
====================
