[ Upstream commit 7db788ad627aabff2b74d4f1a3b68516d0fee0d7 ]
When looking for a global mac index the extra NFP_TUN_PRE_TUN_IDX_BIT
that gets set if nfp_flower_is_supported_bridge is true is not taken
into account. Consequently the path that should release the ida_index
in cleanup is never triggered, causing messages like:
nfp 0000:02:00.0: nfp: Failed to offload MAC on br-ex.
nfp 0000:02:00.0: nfp: Failed to offload MAC on br-ex.
nfp 0000:02:00.0: nfp: Failed to offload MAC on br-ex.
after NFP_MAX_MAC_INDEX number of reconfigs. Ultimately this lead to
new tunnel flows not being offloaded.
Fix this by unsetting the NFP_TUN_PRE_TUN_IDX_BIT before checking if
the port is of type OTHER.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
