Linux kernel source tree

Implement devlink port handlers responsible for ethernet type devlink subfunctions. Create subfunction devlink port and setup all resources needed for a subfunction netdev to operate. Configure new VSI for each new subfunction, initialize and configure interrupts and Tx/Rx resources. Set correct MAC filters and create new netdev. For now, subfunction is limited to only one Tx/Rx queue pair. Only allocate new subfunction VSI with devlink port new command. Allocate and free subfunction MSIX interrupt vectors using new API calls with pci_msix_alloc_irq_at and pci_msix_free_irq. Support both automatic and manual subfunction numbers. If no subfunction number is provided, use xa_alloc to pick a number automatically. This will find the first free index and use that as the number. This reduces burden on users in the simple case where a specific number is not required. It may also be slightly faster to check that a number exists since xarray lookup should be faster than a linear scan of the dyn_ports xarray.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
