When sending non-linear skbs with jumbo frames, we set up the non-paged data and mark that as a last segment, although the paged fragments are also prepared. This will stall the TX queue and trigger a watchdog warning (a simple reproducer is to run an iperf client mode TCP test with a large MTU - networking fails instantly). Fix by checking if the skb is non-linear. Signed-off-by: Aaro Koskinen <aaro.koskinen@nokia.com> Acked-by: Jose Abreu <joabreu@synopsys.com> 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.
