[dpdk-dev] DPDK ethdev/mbuf features and reviews

[Thomas Monjalon]

Hi,

The ethdev library is very special as it defines the services (ops)
to be implemented in every DPDK networking drivers.
It defines also some configuration bits to support.
The mbuf library defines also some offloads to support in drivers.

Some of these features are not enough supported and need more efforts.
You can check this table for a summary:
	http://dpdk.org/doc/guides/nics/overview.html#id1

These features are being summarized by Ferruh who needs help and review:
	http://dpdk.org/patch/26492

We must also take care of the new added features.
Adding a feature means it should be supported by every drivers.
For a PMD maintainer, the first step is to carefully review the new
proposed feature in mbuf or ethdev. The second step is to implement it.

Thanks for your help

Table 1.1 from the above 17.08 doc is missing vmxnet3. The vmxnet3 driver 
is missing from 17.05 doc as well 
(http://dpdk.readthedocs.io/en/v17.05/nics/overview.html) but it is 
present in 17.02 
(http://dpdk.readthedocs.io/en/v17.02/nics/overview.html). Not sure if I 
missed something?

Thanks,
Shri

Depending of your browser, you may need to scroll to the right ;)

Note: you can check old versions on dpdk.org too:
