Subject: [PATCH 0/2] can: add dummy_can termination and update SocketCAN docs

This patch series introduces two changes related to CAN XL support:

  1. Add termination configuration support to the dummy_can driver,
     enabling termination testing with iproute2.

  2. Update the SocketCAN documentation to describe CAN XL operation,
     including MTU changes, bittiming/XBTR settings, mixed-mode
     behaviour, error signalling, and example iproute2 usage.

The goal of this patch series is to improve dummy_can support for termination and
update documentation to match the recent addition of CAN XL upstream support.
Feedback from the maintainers is highly appreciated.

Base commit: 
commit d26143bb38e2 ("Merge tag 'spi-fix-v6.19-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi")

Testing was performed using the iproute2 master tree, which contains the
required CAN XL netlink support for validating these changes.

---
Changes since RFC:
1. Maintain dummy_can structures assignment as is
2. Update the examples with latest iproute2 tool (v6.18.0)
