there is a case where we would return a DID_NO_CONNECT for IO sent to the

fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden  raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume.  In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not

17 years agoe1000: restore netif_poll_enable call but make sure IRQs are off

e1000: restore netif_poll_enable call but make sure IRQs are off

This restores the previously removed netif_poll_enable call in e1000_open.
It's needed on all but the first call to e1000_open for a NIC as
e1000_close always calls netif_poll_disable.

netif_poll_enable can only be called safely if no polls have been
scheduled.  This should be the case as long as we don't enter our IRQ
handler.

In order to guarantee this we explicitly disable IRQs as early as possible
when we're probing the NIC.

sky2: dont set bogus bit in PHY register

This code inherited from the sk98lin driver is incorrect on the Yukon2.
The GPHY_CTRL register values are specific to the internal PHY of the chip
and the values used were leftovers.
Driver was setting bit 13 which is now the INT polarity for the PHY!
