[PATCH net-next 0/48] pull-request: can-next 2025-09-25

[Marc Kleine-Budde <mkl@pengutronix.de>]

Hello netdev-team,

this is a pull request of 48 patches for net-next/main, which
supersedes tags/linux-can-next-for-6.18-20250923.

The 1st patch is by Xichao Zhao and converts ns_to_ktime() to
us_to_ktime() in the m_can driver.

Vincent Mailhol contributes 2 patches: Updating the MAINTAINERS and
mailmap files to Vincent's new email address and sorting the includes
in the CAN helper library alphabeticaly.

Stéphane Grosjean's patch modifies all peak CAN drivers and the
mailmap to reflect Stéphane's new email address.

4 patches by Biju Das update the CAN-FD handling in the rcar_canfd
driver.

Followed by 11 patches by Geert Uytterhoeven updating and improving
the rcar_can driver.

Stefan Mätje contributes 2 patches for the esd_usb driver updating the
error messages.

The next 3 patch series are all by Vincent Mailhol: 3 patches to
optimize the size of struct raw_sock and struct uniqframe. 4 patches
which rework the CAN MTU logic as preparation for CAN-XL interfaces.
And finally 20 patches that prepare and refactor the CAN netlink code
for the upcoming CAN-XL support.

regards,
Marc
