Subject: [PATCH net-next 0/4] mlxsw: Adjust SPAN egress mirroring buffer size handling for Spectrum-2

From: Ido Schimmel <>

Jiri says:

For Spectrum-2 the computation of SPAN egress mirroring buffer uses a
different formula. On top of MTU it needs also current port speed. Fix
the computation and also trigger the buffer size set according to PUDE
event, which happens when port speed changes.

Jiri Pirko (4):
  mlxsw: spectrum: Push code getting port speed into a helper
  mlxsw: spectrum_span: Put buffsize update code into helper function
  mlxsw: spectrum: Fix SPAN egress mirroring buffer size for Spectrum-2
  spectrum: Add a delayed work to update SPAN buffsize according to
