🔥 DESCRIPTION 🔥

so bestie, this one gets called when the system wants to stop or down the interface. like, the interface said "i'm logging off" and this is the function that handles the goodbye 😭

here's the rundown of what we do on the way out:

• we stop the network queue 🛑
• we disable interrupts ⚡
• we cleanup TX/RX channels 🧹

and then — plot twist — we return the statistics in the net_device_stats structure, pulled from emac. yes, we're returning stats on the way out. iykyk 💀
