Netfilter traditionally uses BSD integer types in its
interface headers. This changes it to use the Linux
strict integer types, like everyone else.

Add rate estimator match. The rate estimator match can match on
estimated rates by the RATEEST target. It supports matching on
absolute bps/pps values, comparing two rate estimators and matching
on the difference between two rate estimators.
This is what I use to route outgoing data connections from a FTP
server over two lines based on the available bandwidth:
# estimate outgoing rates
iptables -t mangle -A POSTROUTING -o eth0 -j RATEEST --rateest-name eth0 \
--rateest-interval 250ms \
--rateest-ewma 0.5s
iptables -t mangle -A POSTROUTING -o ppp0 -j RATEEST --rateest-name ppp0 \
--rateest-interval 250ms \
--rateest-ewma 0.5s
# mark based on available bandwidth
iptables -t mangle -A BALANCE -m state --state NEW \
-m helper --helper ftp \
-m rateest --rateest-delta \
--rateest1 eth0 \
--rateest-bps1 2.5mbit \
--rateest-gt \
--rateest2 ppp0 \
--rateest-bps2 2mbit \
-j CONNMARK --set-mark 0x1
iptables -t mangle -A BALANCE -m state --state NEW \
-m helper --helper ftp \
-m rateest --rateest-delta \
--rateest1 ppp0 \
--rateest-bps1 2mbit \
--rateest-gt \
--rateest2 eth0 \
--rateest-bps2 2.5mbit \
-j CONNMARK --set-mark 0x2
iptables -t mangle -A BALANCE -j CONNMARK --restore-mark
