Linux kernel source tree
31f114c3d1
In a multi-PF netdev, each traffic channel creates its own resources
against a specific PF.
In the cited commit, where this support was added, the channel_param
logic was mistakenly kept unchanged, so it always used the primary PF
which is found at priv->mdev.
In this patch we fix this by moving the logic to be per-channel, and
passing the correct mdev instance.
This bug happened to be usually harmless, as the resulting cparam
structures would be the same for all channels, due to identical FW logic
and decisions.
However, in some use cases, like fwreset, this gets broken.
This could lead to different symptoms. Example:
Error cqe on cqn 0x428, ci 0x0, qn 0x10a9, opcode 0xe, syndrome 0x4,
vendor syndrome 0x32

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.
