While determining offload capabilities of backing hardware during a device reset, the driver is clobbering current feature settings. Update hw_features on reset instead of features unless a feature is enabled that is no longer supported on the current backing device. Also enable features that were not supported prior to the reset but were previously enabled or requested by the user. This can occur if the reset is the result of a carrier change, such as a device failover or partition migration. Signed-off-by: Thomas Falcon <tlfalcon@linux.ibm.com> Signed-off-by: David S.

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.
