Merge branch 'pie-next'
Leslie Monis says: ==================== net: sched: pie: align PIE implementation with RFC 8033 The current implementation of the PIE queuing discipline is according to the IETF draft [http://tools.ietf.org/html/draft-pan-aqm-pie-00] and the paper [PIE: A Lightweight Control Scheme to Address the Bufferbloat Problem]. However, a lot of necessary modifications and enhancements have been proposed in RFC 8033, which have not yet been incorporated in the source code of Linux. This patch series helps in achieving the same. Performance tests carried out using Flent [https://flent.org/] Changes from v2 to v3: - Used div_u64() instead of direct division after explicit type casting as recommended by David Changes from v1 to v2: - Excluded the patch setting PIE dynamically active/inactive as the test results were unsatisfactory - Fixed a scaling issue when adding more auto-tuning cases which caused local variables to underflow - Changed the long if/else chain to a loop as suggested by Stephen - Changed the position of the accu_prob variable in the pie_vars structure as recommended by Stephen ==================== Acked-by: NDave Taht <dave.taht@gmail.com> Acked-by: NJamal Hadi Salim <jhs@mojatatu.com> Signed-off-by: NDavid S.
