The current code does not like being given an u16 with the highest
bit set as an argument to mdio_write. Let's enforce a correct range of

The link state machine requires access to some resources that
are shared with the iSCSI function on the chip.  (See iSCSI
driver at drivers/scsi/qla4xxx)  If the interface is being
up/downed at a rapid pace this driver may need to sleep
waiting to get access to the common resources. For this we
are moving the state machine to run as a work thread.

The standard validate_addr handler refuses to accept the all zeroes address
as valid.  However, it's common historical practice for the bonding
master to be configured up prior to having any slaves, at which time the
master will have a MAC address of all zeroes.

Resolved by setting the dev->validate_addr to NULL.  The master still can't
end up with an invalid address, as the set_mac_address function tests
for validity.

	Looks like I incorrectly merged one of the rtnl lock changes,
so that one function, bonding_show_active_slave, held rtnl but didn't
release it, and another, bonding_store_active_slave, never held rtnl but
did release it.

	Fixed so the first function doesn't mess with rtnl, and the
second correctly acquires and releases rtnl.

Fix an IRQ race condition in b43legacy. If we call
b43legacy_wireless_core_stop(), it will set the status of the device to
INITIALIZED and the IRQ handler won't care any longer about IRQs, thus the
kernel will disable the IRQ if it's shared (unless we boot it with the
'irqpoll' option). So we must disable IRQs before changing the device
status.
