Subject: [ANNOUNCE] iproute2 6.19.0 release

This is the regular release of iproute2 corresponding to the 6.19 kernel.

The biggest addition is a new `dpll` command for managing Digital
Phase-Locked Loop devices via netlink, which also prompted refactoring
the `mnlg` library into a shared location. CAN XL support saw major
expansion with seven patches from Vincent Mailhol adding transceiver
mode setting, PWM configuration, and a RESTRICTED operation
mode. MPTCP gained a new `laminar` endpoint type and several monitor
improvements from Matthieu Baerts, who also added a MAINTAINERS entry
for the subsystem.

On the devlink side, there's now support for 64-bit parameters, a new
`SWITCHDEV_INACTIVE` eswitch mode, and burst period configuration for
health reporters. The `genl` utility picked up JSON output
support. Andrea Claudi modernized `ifstat`, `nstat`, and `lnstat` by
converting them to the high-level `json_print` API for consistent JSON
output.

Rounding things out are smaller fixes: per-CPU support for XFRM, HSR
protocol version display, an off-by-one fix in iplink, a musl libc
build fix, and assorted man page corrections.
