Introduce a new random number function to get a floating
point value. Then use it to fix PIE scheduler.
v5
- use divide method (similar to FreeBSD)
it takes same number of cycles (after optimization)
and works on all platforms.
Stephen Hemminger (3):
random: add rte_drand() function
rte_pie: remove unnecessary floating point
rte_pie: fix incorrect floating point math
