Define and implement a new per-route feature, RTAX_FEATURE_ECN_LOW.
This feature indicates that the given destination network is a
low-latency ECN environment, meaning both that ECN CE marks are
applied by the network using a low-latency marking threshold and also
that TCP endpoints provide precise per-data-segment ECN feedback in
ACKs (where the ACK ECE flag echoes the received CE status of all
newly-acknowledged data segments). This feature indication can be used
by congestion control algorithms to decide how to interpret ECN
signals over the given destination network.
This feature is appropriate for datacenter-style ECN marking, such as
the ECN marking approach expected by DCTCP or BBR congestion control
modules.

[ Upstream commit 84bfbfbbd32aee136afea4b6bf82581dce79c305 ]
This commit fix a typographical error in netlink nlmsg_type constants definition in the include/uapi/linux/rtnetlink.h at line 177. The definition is RTM_NEWNVLAN RTM_NEWVLAN instead of RTM_NEWVLAN RTM_NEWVLAN.
