Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Cross-merge networking fixes after downstream PR (net-6.15-rc2). Conflict: Documentation/networking/netdevices.rst net/core/lock_debug.c 04efcee6ef8d ("net: hold instance lock during NETDEV_CHANGE") 03df156dd3a6 ("xdp: double protect netdev->xdp_flags with netdev->lock") No adjacent changes.
