Fwd: PMD for Broadcom/Emulex OCe14000 OCP Skyhawk-R

Fwd: PMD for Broadcom/Emulex OCe14000 OCP Skyhawk-R

[sujith sankar]

Hi all,

Is PMD for Broadcom/Emulex OCe14000 OCP Skyhawk-R available?  There
are a few documents in Broadcom's site.  But could not find the source
code of it.

I believe 6Wind team developed the PMD for Broadcom.  But what is the
status of it?  Is it freely available?

Tried to get some help from users alias, but could not.
Could someone please help me with info on this?

Thanks,
-Sujith

Right, it has not been upstreamed. Currently, it is even deprecated at 
6WIND for our new releases.
   www.6wind.com/products/6windgate/6windgate-platfoarm-support/
see the NIC section.

I guess you are referring to:
   https://docs.broadcom.com/docs/12356248

This PMD is deprecated. We kept it only for old DPDK releases because it 
relies on some specific SDK from Emulex/Skyhawk's designers! The PMD 
without the SDK is useless.

In fact, the best option is to use AF_XDP PMD if you need to support 
this Emulex/SkyhawkNIC. Please, give a try to this AF_XDP PMD. Your 
benchmarks will be welcomed. I guess it is better to invest time in 
improving AF_XDP PMD,
