[EXT] [PATCH] examples/l2fwd-crypto: fix stats refresh rate

[Akhil Goyal]

> TIMER_MILLISECOND is defined as the number of cpu cycles per millisecond,
> current definition is correct for cores with frequency of 2GHZ, for cores
> with different frequency, it caused different periods between refresh,
> (i.e. the definition is about 14ms on ARM cores).
> The devarg that stated the period between stats print was not used,
> instead, it was always defaulted to 10 seconds (on 2GHZ core).
> 
> Use dpdk API to get CPU frequency, to define TIMER_MILLISECOND.
> Use the refresh period devarg instead of defaulting to 10s always.
