[PATCH net-next v3 0/5] net: tcp: DCTCP congestion control algorithm

[Daniel Borkmann <dborkman@redhat.com>]

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

Thanks !
