Constant SIXLOWPAN_ADDRESS_CONTEXT_COUNT 

pub const SIXLOWPAN_ADDRESS_CONTEXT_COUNT: usize = raw::SIXLOWPAN_ADDRESS_CONTEXT_COUNT; // 4usize

Max 6LoWPAN address contexts an interface can hold at once.

Contexts are used to decompress addresses of incoming packets. Setting more than this many fails with Full. A packet can only name 16 of them, since the context identifier is 4 bits wide.

Ignored with alloc. Default: 4.
