From: Ido Schimmel <idosch@mellanox.com> Petr says: In order to allow configuration of shapers on Spectrum family of machines, recognize TBF either as root Qdisc, or as a child of ETS or PRIO. Configure rate of maximum shaper according to TBF rate setting, and maximum shaper burst size according to TBF burst setting. - Patches #1 and #2 make the TBF shaper suitable for offloading. - Patches #3, #4 and #5 are refactoring aimed at easier support of leaf Qdiscs in general. - Patches #6 to #10 gradually introduce TBF offload. - Patches #11 to #14 add selftests.
