atl1c: threshold for ASPM is changed based on chip capability
threshold setting to control ASPM for diff chips are different. currently, all gigabit-capability chips have limited-ASPM under 100M throughput. Signed-off-by: xiong <xiong@qca.qualcomm.com> Tested-by: Liu David <dwliu@qca.qualcomm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
