💅 DESCRIPTION 💅

so here’s the vibe, bestie: this function disables PCI-Express master access and verifies there are no pending requests. that’s the whole mission 🎯

Return-value check, because we love clarity: it returns 0 if successful. If the master disable bit has not caused the master requests to be disabled, it returns -10 — aka -E1000_ERR_MASTER_REQUESTS_PENDING. so yeah, that negative number is the “requests are still pending” alert 🚨
