Module replay 

Live packet replay onto a real network interface.

Reads packets from a PCAP file and injects them via a raw AF_PACKET socket (Linux only) using the original or a scaled inter-packet timing.

Timing modes

CLI flag	Behaviour
(none)	Real-time: honour original inter-packet gaps
--speed 2.0	Multiplier: replay 2× faster than original
--speed max	No delay — transmit as fast as the NIC allows
--pps 4096	Fixed rate: 4 096 packets/second, ignores gaps

Permissions

Raw sockets require CAP_NET_RAW. If the capability is absent the function returns ReplayError::PermissionDenied with a remediation hint.
