[net-next v3 00/14] Add Marvell CN10K support

[net-next v3 00/14] Add Marvell CN10K support

[Geetha sowjanya]

The current admin function (AF) driver and the netdev driver supports
OcteonTx2 silicon variants. The same OcteonTx2's
Resource Virtualization Unit (RVU) is carried forward to the next-gen
silicon ie OcteonTx3, with some changes and feature enhancements.

This patch set adds support for OcteonTx3 (CN10K) silicon and gets
the drivers to the same level as OcteonTx2. No new OcteonTx3 specific
features are added.

Changes cover below HW level differences
- PCIe BAR address changes wrt shared mailbox memory region
- Receive buffer freeing to HW
- Transmit packet's descriptor submission to HW
- Programmable HW interface identifiers (channels)
- Increased MTU support
- A Serdes MAC block (RPM) configuration

FYI, it didn't work, suggest you try adding the git-send-email option
(via git-config)

sendemail.thread=true
sendemail.chainreplyto=false

And you can test locally by using first using git send-email to export
to mbox and checking for References and In-Reply-to headers. Then
sending for real.

Good luck!

And looks like there are build issues so you'll get a chance to try
again :/

Please make sure you don't add any new warnings to the build, with W=1
C=1 flags. Each patch must build cleanly.

Shooting from the hip something along the lines of:

 make allmodconfig
 current=$(make W=1 C=1 | wc -l)

 git rebase --exec '[ $current -eq $(make W=1 C=1 | wc -l) ]'

Please do not repost until the tree can build cleanly at every commit
of the series.
