[ Upstream commit bbc8222dc49db8d49add0f27bcac33f4b92193dc ]
External controller PF's MAC address is not read from the device during
vport setup. Fail to read this results in showing all zeros to user
while the factory programmed MAC is a valid value.
$ devlink port show eth1 -jp
{
"port": {
"pci/0000:03:00.0/196608": {
"type": "eth",
"netdev": "eth1",
"flavour": "pcipf",
"controller": 1,
"pfnum": 0,
"splittable": false,
"function": {
"hw_addr": "00:00:00:00:00:00"
}
}
}
}
Hence, read it when enabling a vport.
After the fix,
$ devlink port show eth1 -jp
{
"port": {
"pci/0000:03:00.0/196608": {
"type": "eth",
"netdev": "eth1",
"flavour": "pcipf",
"controller": 1,
"pfnum": 0,
"splittable": false,
"function": {
"hw_addr": "98:03:9b:a0:60:11"
}
}
}
}

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.
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.
