Use /sys/module/aoe/parameters/aoe_iflist (or better, the driver
option discussed below) instead of /dev/etherd/interfaces to limit
AoE traffic to the network interfaces in the given
whitespace-separated list. Unlike the old character device, the
sysfs entry can be read from as well as written to.
It's helpful to trigger discovery after setting the list of allowed
interfaces. The aoetools package provides an aoe-discover script
for this purpose. You can also directly use the
/dev/etherd/discover special file described above.
DRIVER OPTIONS
There is a boot option for the built-in aoe driver and a
corresponding module parameter, aoe_iflist. Without this option,
all network interfaces may be used for ATA over Ethernet. Here is a
usage example for the module parameter.

These functions are intended for use by individual drivers, and are defined in
struct pci_driver:
int (*save_state) (struct pci_dev *dev, u32 state);
int (*suspend) (struct pci_dev *dev, u32 state);

save_state
----------
Usage:
if (dev->driver && dev->driver->save_state)
dev->driver->save_state(dev,state);
The driver should use this callback to save device state. It should take into
account the current state of the device and the requested state in order to
avoid any unnecessary operations.
For example, a video card that supports all 4 states (D0-D3), all controller
context is preserved when entering D1, but the screen is placed into a low power
state (blanked).
The driver can also interpret this function as a notification that it may be
entering a sleep state in the near future. If it knows that the device cannot
enter the requested state, either because of lack of support for it, or because
the device is middle of some critical operation, then it should fail.
This function should not be used to set any state in the device or the driver
because the device may not actually enter the sleep state (e.g. another driver
later causes causes a global state transition to fail).
Note that in intermediate low power states, a device's I/O and memory spaces may
be disabled and may not be available in subsequent transitions to lower power
states.
