Subject: [RFT v2 0/3] pie: fix random number issues
Date: Tue, 24 May 2022 15:18:21 -0700	[thread overview]
Message-ID: <20220524221824.1037693-1-stephen@networkplumber.org> (raw)
In-Reply-To: <20220524184623.480646-1-stephen@networkplumber.org>

Alternate way to fix PIE use of random by introducing a fast
way to get a random floating point number. It ends up
not needing floating point math.

Stephen Hemminger (3):
  random: add rte_rand_float()
  rte_pie: remove unnecessary floating point
  rte_pie: fix incorrect floating point math
