Finn Thain eaabfd19b2 net/sonic: Avoid needless receive descriptor EOL flag updates ... The while loop in sonic_rx() traverses the rx descriptor ring. It stops when it reaches a descriptor that the SONIC has not used. Each iteration advances the EOL flag so the SONIC can keep using more descriptors. Therefore, the while loop has no definite termination condition. The algorithm described in the National Semiconductor literature is quite different. It consumes descriptors up to the one with its EOL flag set (which will also have its "in use" flag set). All freed descriptors are then returned to the ring at once, by adjusting the EOL flags (and link pointers). Adopt the algorithm from datasheet as it's simpler, terminates quickly and avoids a lot of pointless descriptor EOL flag changes.
