Miroslav Lichvar 0ae6f2485b ntp: don't use first response in interleaved mode 
With the first interleaved response coming after a basic response the
client is forced to select the four timestamps covering most of the last
polling interval, which makes measured delay very sensitive to the
frequency offset between server and client. To avoid corrupting the
minimum delay held in sourcestats (which can cause testC failures),
reject the first interleaved response in the client/server mode as
failing the test A.

This does not change anything for the symmetric mode, where both sets of
the four timestamps generally cover a significant part of the polling
interval.

README 

This is a collection of simulation tests using the clknetsim simulator
(supported on Linux only).

https://github.com/mlichvar/clknetsim

The CLKNETSIM_PATH environment variable should point to the directory where
clknetsim was downloaded and compiled. If the variable is not set, the tests
will look for clknetsim in ./clknetsim in the current directory.

The tests are written in bash and they can be run directly. The ./run script
runs all tests.
