The memory management API is the set of calls used by library to perform dynamic memory allocation/deallocation, as well as other memory operations (like copy or move).

The user MUST provide an implementation for his/her particular platform.

The calls sufixed with "_shared" are meant to allocate memory that is shared between all the threads, hardware threads, cores or in general any system, that may perform operations (flow entry insertions, packet pipeline transvering...) over the SAME logical switch.

In a typical POSIX/libc system this would probably be directly malloc/free and the respective other calls, except maybe for the "_shared_" calls (depending on the threading/process used). E.g. in a single process application "_shared" and non-shared mallocs/free maps to the same LIBC malloc/free
