In the Linux kernel, the following vulnerability has been resolved:
nfp: flower: Fix a potential leak in nfp_tunnel_add_shared_mac()
ida_simple_get() returns an id between min (0) and max (NFP_MAX_MAC_INDEX) inclusive. So NFP_MAX_MAC_INDEX (0xff) is a valid id.
In order for the error handling path to work correctly, the 'invalid' value for 'ida_idx' should not be in the 0..NFP_MAX_MAC_INDEX range, inclusive.
So set it to -1.
