📋 Description

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: cortina: Fix budget accounting

The gmac_rx() function returns the remaining NAPI budget, but its caller treats the return value as the number of packets received. An idle poll therefore reports a full budget and remains scheduled.

Return the number of received packets instead. Preserve the existing free queue refill accounting by adding that count directly; continuing to subtract it from the budget would invert the refill behavior.
