🦋 DESCRIPTION 🦋

so like, this page is where the port-specific registers live — the ones you've gotta access on a per-port basis (iykyk, one port at a time, no group-chat shortcuts 🙈).

it's giving very main-character-registry energy, and it includes controls for:

• the port LEDs 💡 (yes, the blinkies have a home)
• the QSGMII PCS 🔥
• the rate adaptation FIFOs 🌈
• the per-port 1588 TSU block ⭐ (timestamping girlies, this one's for you)
