Jakub Kicinski says: ==================== nfp: fix retcode and disable netpoll on representors This series avoids a potential crash on nfp representor devices when netpoll is in use. If transmitting the frame through underlying vNIC fails we'd return an error code (by passing on error code from __dev_queue_xmit()) and cause double free in netpoll code. Fix the error code and disable netpoll on reprs altogether. IRQ-safety of locking the queues and calling __dev_queue_xmit() is questionable. Big thanks to John Hurley for debugging and narrowing down the trace log after I gave up! :) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
