Subject: [PATCH iproute2 3/3] ip: Get rid of custom netinet/tcp.h
It seems to be copied from one of the versions of glibc to address
build issues caused by missing functionality.
Since then even with glibc-2.13 and Linux Kernel headers from 3.2
we able to build iproute2 tools (including ss) successfuly.
This effectively reverts commit 719b958bbdfd ("ss: report ecnseen")
and original one introducing this include commit 76e5d2c39201 ("add
include/netinet/tcp.h").
Any missing functionality and compatibility stuff must go to "compat"
subdirectory in include/.
