88e1111驱动函数如下：

{
.phy_id = MARVELL_PHY_ID_88E1111,
.phy_id_mask = MARVELL_PHY_ID_MASK,
.name = "Marvell 88E1111",
.features = PHY_GBIT_FEATURES,
.flags = PHY_HAS_INTERRUPT,
.config_init = &m88e1111_config_init,
.config_aneg = &marvell_config_aneg,
.read_status = &marvell_read_status,
.ack_interrupt = &marvell_ack_interrupt,
.config_intr = &marvell_config_intr,
.driver = { .owner = THIS_MODULE },
},

通过添加打印发现驱动接口只运行到marvell_config_aneg接口就没向下运行了。

.read_status = &marvell_read_status,
.ack_interrupt = &marvell_ack_interrupt,
.config_intr = &marvell_config_intr,

都没运行，请问下，marvell_read_status这个接口的触发条件是什么？什么情况下调用这个接口？为什么到这个地方就不向下调用了？
