Subject: [PATCH net-next 00/14] mlxsw: Offload TBF
Date: Fri, 24 Jan 2020 15:23:04 +0200 [thread overview]
Message-ID: <20200124132318.712354-1-idosch@idosch.org> (raw)
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.
