Linux kernel source tree

Every time I create VFs on ice, I receive at least one "Device is still in reset (-16), retrying" message per VF. It recovers fine, but typical usecases should not trigger scary-looking messages. The waiting for reset is too short. It makes no sense to check every 10 microseconds. Typical reset waiting times are at least tens of milliseconds and can be several seconds. I suspect the polling interval was meant to be 10 milliseconds all along. IAVF_RESET_WAIT_COMPLETE_COUNT is defined as 2000, so the total waiting time could be over 20 seconds. I have seen resets take 5 seconds (with 128 VFs on ice). The added benefit of not triggering the "Device is still in reset" path is that we avoid going through the __IAVF_INIT_FAILED state, which would take a full second before retrying.

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.
