Linux kernel source tree
cab43d9c87
The mlxsw driver currently doesn't offload GRE tunnels if they have the
same local address and use the same underlay VRF. When such a situation
arises, the tunnels in conflict are demoted to slow path.
However, the current code only verifies this condition on tunnel
creation and tunnel change, not when a tunnel is moved to a different
VRF. When the tunnel has no bound device, underlay and overlay are the
same. Thus moving a tunnel moves the underlay as well, and that can
cause local address conflict.
So modify mlxsw_sp_netdevice_ipip_ol_vrf_event() to check if there are
any conflicting tunnels, and demote them if yes.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
