[PATCH v5 0/3] introduce random floating point function

[Stephen Hemminger]

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
