Oops.

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
values for both the register address and value (resp. 5 and 16 bits).

The callers are currently left as-is.

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

'irqpoll' option). So we must disable IRQs before changing the device

It may not be configured into the kernel or there may be a BIOS

PCI space in the device, so use that.
