What: /sys/block/etherd*/mac
Date: Apr, 2005

What: /sys/block/etherd*/state
Date: Apr, 2005
KernelVersion: v2.6.12
Contact: Ed L. Cashin <ed.cashin@acm.org>
Description:
(RO) Device status. The state attribute is "up" when the device
is ready for I/O and "down" if detected but unusable. The
"down,closewait" state shows that the device is still open and
cannot come up again until it has been closed. The "up,kickme"
state means that the driver wants to send more commands to the
target but found out there were already the max number of
commands waiting for a response. It will retry again after being
kicked by the periodic timer handler routine.
