Date: Wed, 23 Jan 2019 12:04:53 -0800
Subject: tcp_bbr: refactor bbr_target_cwnd() for general inflight provisioning
Because bbr_target_cwnd() is really a general-purpose BBR helper for
computing some volume of inflight data as a function of the estimated
BDP, refactor it into following helper functions:
- bbr_bdp()
- bbr_quantization_budget()
- bbr_inflight()
