LX2160ARDB 10 GbE Coalescing

ash_law · ‎12-03-2019

It looks like the standard DPAA2 drivers don't support interrupt coalescing on the LX2160ARDB, or at least ethtool can't turn coalescing on. Is there some other way to turn this on, or do I need to use some other driver?

If so does anyone know which one, and how to I add it and remove the dpaa2 drivers. Do I just use modprobe, or is something else needed?

Thanks

Unfortunately, there is no support for coalescing interrupts from DPAA2-managed network interfaces in the current LSDK release, so you cannot enable it by loading or replacing any module. This feature is planned to be added in future LSDK

releases.

Well that's disappointing. Is there a different driver I can use as opposed to the dpaa2? The interrupts are killing our processing.

Thanks

I'm not aware of any alternative driver for DPAA-2 controlled network
interfaces, I don't think anything similar exists. For requests of
this kind, our suggestion is to discuss the desired features with
our Professional Engineering team
