When trying to determine whether there are other offloaded tunnels with the same local address, mlxsw_sp_ipip_entry_create() should look for a tunnel with matching UL protocol, matching saddr, in the same VRF. However instead of taking into account the UL protocol of the tunnel netdevice (which mlxsw_sp_ipip_entry_saddr_matches() then compares to the UL protocol of inspected IPIP entry), it deduces the UL protocol from the inspected IPIP entry (and that's compared to itself). This is currently immaterial, because only one tunnel type is offloaded, and therefore the UL protocol always matches, but introducing support for a tunnel with IPv6 underlay would uncover this error.

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.
