ofproto-dpif: Add coverage counters for facet revalidation.
		
Revalidation can be very expensive, so may be useful for performance
monitoring to keep track of how often it is necessary and for what reasons.

netdev-linux: Break ethtool coverage counter into "get" and "set" versions.
		
Reads and writes have difference performance implications so it's better to
separate them.

token-bucket: New library for generic rate-limiting.
		
This commit converts two rate-limiters in the tree to use the library.
I intend to use the library elsewhere in the future.

sat-math: Introduce macro version of SAT_MUL.
		
The macro version can be used in a constant expression, such as an
initializer for a variable with static lifetime.  (Otherwise, it's better
to use the function.)

commit 68941e3f99fb5a3e1ef7f7b7b700b252c1f4d82f
Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=68941e3f99fb5a3e1ef7f7b7b700b252c1f4d82f

pinsched: Completely fill the token bucket at initialization.
		
This code, which dates to August 2008, initially sets the packet-in
scheduler token buckets to 10% full, without any rationale.  I suspect
that this is just a typo for 100% full, which I think would be more
conventional, so this commit switches to that.
