PCI PFs can host more than one logical endpoint. In NFP terms this means having more than one vNIC for PCIe PF. The vNICs are usually corresponding 1:1 to Ethernet ports. In core NIC we use the legacy idea of vNIC *being* the Ethernet port, hence netdevs put pX(sY) in their phys_port_name, like Ethernet ports would. When ASIC ports are fully represented we need to be able to name different PCIe PF ports, too. Use a scheme similar to Ethernet ports - pfXsY, for PCIe PF number X, sub-port Y.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
