Maximum size of the static packet buffer.
The rational here is to have at least space for 4 full-MTU IPv6 packages (2 incoming, 2 outgoing; 2 * 2 * 1280 B = 5 KiB) + Meta-Data (roughly estimated to 1 KiB; might be smaller). If CONFIG_GNRC_PKTBUF_SIZE is 0 the packet buffer will use dynamic memory management to allocate packets.
