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
