Decode ARP hardware/protocol types, operation, and sender/target addresses from raw hex.

How it works

Decode an ARP packet beginning at the hardware type field. Address lengths are taken from the packet and bounded against the supplied bytes. Ethernet/IPv4 addresses are formatted when those types and lengths match; other address forms remain raw hex.
