- merge dante.go and dante_control.go into single dante.go - consolidate buildDantePacket and buildDantePacket28 into one function - fix broken comparison logic in SetDanteClockMaster - split ARP parsing into platform-specific files with build tags - implement Linux ARP table parsing via /proc/net/arp - run gofmt on all files Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
