Is there any logic that guards against the following cases where the target device is: - outside of the switch hardware/cluster (which would imply going through software)? - has a downstream speed which is lower than the mirrored device? this might already be in place for 1), I just could not locate it, thanks! > > These patches contain: > - Resource query implementation > - Hardware port mirorring support for spectrum. > - Definition of the matchall traffic classifier. > - General support for hw-offloading for that classifier. > - Specific spectrum implementaion for matchall offloading. > > --- > v1->v2: > - couple of minor style fixes > > Jiri Pirko (1): > net/sched: introduce Match-all classifier > > Nogah Frankel (2): > mlxsw: pci: Add resources query implementation. > mlxsw: pci: Add max span resources to resources query > > Yotam Gigi (6): > net/sched: Add match-all classifier hw offloading. > mlxsw: reg: Add Shared Buffer Internal Buffer register > mlxsw: reg: Add Monitoring Port Analyzer Table register > mlxsw: reg: Add the Monitoring Port Analyzer register > net/sched: act_mirred: Add helper inlines to access tcf_mirred info. > mlxsw: spectrum: Add support in matchall mirror TC offloading > > drivers/net/ethernet/mellanox/mlxsw/cmd.h | 32 ++ > drivers/net/ethernet/mellanox/mlxsw/core.c | 10 +- > drivers/net/ethernet/mellanox/mlxsw/core.h | 11 +- > drivers/net/ethernet/mellanox/mlxsw/pci.c | 64 +++- > drivers/net/ethernet/mellanox/mlxsw/reg.h | 162 +++++++++ > drivers/net/ethernet/mellanox/mlxsw/spectrum.c | 465 > ++++++++++++++++++++++++- > drivers/net/ethernet/mellanox/mlxsw/spectrum.h | 44 +++ > drivers/net/ethernet/mellanox/mlxsw/switchx2.c | 1 + > include/linux/netdevice.h | 2 + > include/net/pkt_cls.h | 11 + > include/net/tc_act/tc_mirred.h | 9 + > include/uapi/linux/pkt_cls.h | 12 + > net/sched/Kconfig | 10 + > net/sched/Makefile | 1 + > net/sched/cls_matchall.c | 318 +++++++++++++++++ > 15 files changed, 1148 insertions(+), 4 deletions(-) > create mode 100644 net/sched/cls_matchall.c > -- Florian
