A vulnerability in the Linux kernel's ethernet cortina driver was fixed by correcting the gmac_rx() function's return value handling. The function previously returned the remaining NAPI budget, but its caller misinterpreted this as the number of packets received, causing an idle poll to report a full budget and remain scheduled unnecessarily. The fix returns the actual number of received packets and adjusts the free queue refill accounting accordingly.
