Key RSC RSC

The starting packet number for the group key being installed.

Reading a capture

Little-endian, in a big-endian structure, because it is a packet number of the kind the CCMP header uses rather than an 802.1X field. One octet order boundary inside a single lane — which is why endianness is declared per node here and never inherited.
