Subject: [PATCH 2/2 net-next] ipvlan: Remove usage of the deprecated ida_simple_xx() API
Date: Fri,  5 Jan 2024 10:27:09 +0100

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.

Note that the upper bound of ida_alloc_range() is inclusive while the one
of ida_simple_get() was exclusive. So calls have been updated accordingly.
