Last time we asked such question, it was for DLB, and it became clear later that it should be the same code, otherwise you fix bugs two times, etc. I understand it is a new silicon, but do you know the net driver mlx5 is the same for various hardware of the last 10 years? > From: Thomas Monjalon > > 24/03/2022 09:32, Mcnamara, John: > > > * DLB allow assignment of SW/HW credit quanta assignment on port usage > > > hint > > > * DLB allow dlb2 eventdev apps to use specific COS on per port basis > > > * DLB add support for DLB 2.5 QE weight hardware feature > > > > DLB and DLB2 were introduced as different but very similar drivers, and they > > got eventually merged. > > > > > * bbdev new PMD for Intel ACC101 device > > > > Is it really going to be a separate driver of ACC100?
