Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
c40e89fd35
Currently, on a new link creation or when 'remote' address parameter is updated, an MTU is not changed and always equals 1500. When a lower device has a larger MTU, it might not be efficient, e.g. for UDP, and requires the manual MTU adjustments to match the MTU of the lower device. This patch tries to automate this process, finds a lower device using the 'remote' address parameter, then uses its MTU to tune GENEVE's MTU: * on a new link creation * when 'remote' parameter is changed Also with this patch, the MTU from a user, on a new link creation, is passed to geneve_change_mtu() where it is verified, and MTU adjustments with a lower device is skipped in that case. Prior that change, it was possible to set the invalid MTU values on a new link creation. Signed-off-by: Alexey Kodanev <alexey.kodanev@oracle.com> Signed-off-by: David S.

README
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
