Constant REASSEMBLY_BUFFER_COUNT 

pub const REASSEMBLY_BUFFER_COUNT: usize = raw::REASSEMBLY_BUFFER_COUNT; // 1usize

Max datagrams reassembled at once, IPv4 and 6LoWPAN together.

Each one holds a packet buffer until it is complete or its reassembly timeout expires. Fragments of further datagrams are dropped.

This is a limit with and without alloc. Default: 1.
