- scheduler_main(). They will be documented below. For now, we skip these implementations and go

Lets digest this line step by step: We declare a variable named \c packet as a smart pointer to
an \c EthernetPacket instance. \c ptr is a typedef member of all Packet classes for the
corresponding smart pointer type. We then initialize this pointer with a call to the static \c
