The patch series add the nbl driver, which will support the nebula-matrix 18100 and 18110 series 
of network cards.
This submission is the first phase. which includes the PF-based and VF-based Ethernet transmit 
and receive functionality. Once this is merged. will submit addition patches to implement support
for other features. such as ethtool support, debugfs support and etc.
Our Driver architecture  supports Kernel Mode and Coexistence Mode(kernel and dpdk)

illusion.wang (15):
  net/nebula-matrix: add minimum nbl build framework
  net/nebula-matrix: add simple probe/remove.
  net/nebula-matrix: add HW layer definitions and implementation
  net/nebula-matrix: add Channel layer definitions and implementation
  net/nebula-matrix: add Resource layer definitions and implementation
  net/nebula-matrix: add intr resource definitions and implementation
  net/nebula-matrix: add vsi, queue, adminq resource definitions and
    implementation
  net/nebula-matrix: add flow resource definitions and implementation
  net/nebula-matrix: add txrx resource definitions and implementation
  net/nebula-matrix: add Dispatch layer definitions and implementation
  net/nebula-matrix: add Service layer definitions and implementation
  net/nebula-matrix: add Dev layer definitions and implementation
  net/nebula-matrix: add Dev start, stop operation
  net/nebula-matrix: fully support ndo operations
  net/nebula-matrix: add kernel/user coexist mode support

Not a real review, but this series has several basic issues:

- each patch should compile and build without warnings on all arches
- don't use inline in c code
- avoid using 'module_params'
- the preferred line width is still 80 chars
- strip changed-id from the commit message
- respect the reverse christmas tree order for variable declaration
- commit messages lines should be wrapped at 72 chars

Note that you can clone the NIPA repository:

https://github.com/linux-netdev/nipa/

and use the ingest_mdir.py script to validate most of the above check
before submission (otherwise you should do that manually).

However...

## Form letter - net-next-closed

The net-next tree is closed for new drivers, features, code refactoring
and optimizations due to the merge window and the winter break. We are
currently accepting bug fixes only.

Please repost when net-next reopens after Jan 2nd.

RFC patches sent for review only are obviously welcome at any time.

Thanks for your quick reply!
However, I noticed that at
https://github.com/torvalds/linux/commit/bdc48fa11e46f867ea4d75fa59ee87a7f48be144,
And the checkpatch tool checks for a line width of 100 columns. If we make the change to 80 characters, it might reduce readability.
Could our driver set the limit to 100 columns instead?

Please use consistent top quoting in your next replies. This one is
quite unreadable.

Networking still uses 80 column boundaries: please adapt your code
accordingly.

Thanks,
