Hi Christophe,

ida_simple_get() returns an id between min (0) and max (NFP_MAX_MAC_INDEX)

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.
While at it, use ida_alloc_xxx()/ida_free() instead to
ida_simple_get()/ida_simple_remove().
The latter is deprecated and more verbose.

Thanks for your patch.
I agree that it is indeed a problem and your fix looks good.
I would, however, prefer if the patch was split into two:
1. Bug fix
2. ida_alloc_xxx()/ida_free() cleanup
I'll send a v2.
I added it because some other maintainers have asked for it in other
similar patches. Everyone's taste is different :).

Thanks again,
Simon
