	Entry in the 6LoWPAN context buffer. More...

Macros
#define	GNRC_SIXLOWPAN_CTX_SIZE (16)
	maximum number of entries in context buffer

Functions
gnrc_sixlowpan_ctx_t *	gnrc_sixlowpan_ctx_lookup_addr (const ipv6_addr_t *addr)

	Gets context by ID. More...

gnrc_sixlowpan_ctx_t *	gnrc_sixlowpan_ctx_update (uint8_t id, const ipv6_addr_t *prefix, uint8_t prefix_len, uint16_t ltime, bool comp)
	Updates (or adds if currently not registered) a context. More...

void	gnrc_sixlowpan_ctx_reset (void)
	Resets the whole context buffer.

Context flags.
Flags to set in gnrc_sixlowpan_ctx_t::flags_id.
#define	GNRC_SIXLOWPAN_CTX_FLAGS_CID_MASK (0x0f)
	mask for the Context ID.

#define	GNRC_SIXLOWPAN_CTX_FLAGS_COMP (0x10)
