We must call netif_carrier_off() after the device is registered, not
before, to set the operational state and user-space IFF_RUNNING flag
correctly.
Since we don't want observers to see an intermediate state, open-code
register_netdev() and add efx_update_name() and netif_carrier_off()
into the locked region.

If nothing has been written into the qeth sysfs-attribute layer2,
its value is "-1" meaning "not yet defined". But the value is
displayed as "1" meaning "layer2 selected". The patch changes the
reading of this "-1"-value to "-1" to make clear the layer2-attribute
has not yet been defined.

In case the IP address list contains entries (not removed when the device was set
offline) this entries should be registered next time the device is brought online.
In the past this was done implicitly with the device open call but since we wait
in the set IPv4 IPA and the device open common code holds various locks this
does not work any longer.

Broadcom's phys come in two distinctly different register layouts. For
the lack of an official term to distinguish between the two formats, we

This patch prevents a tx BD corruption bug by preventing the device from

When the interface is put in bridged mode, destination mac
addresses are unknown to firmware. So packets take a slow
path (lower priority) in firmware reducing performance.
Firmware can cache limited number of remote unicast mac
addresses for certain interval, if "dynamic mac learning"
mode is enabled.
Driver needs to enable this "mac learning" mode in firmware.
Currently this is done through net device class sysfs entry,
possibly this can also be done upon netlink notifications to
from bridge.

This patch adds support of USB autosuspend to the btusb driver.
If the device doesn't support remote wakeup, simple support based on
up/down is provided. If the device supports remote wakeup, additional
support for autosuspend while the interface is up is provided. This is
done by queueing URBs in an anchor structure and waking the device up
from a work queue on sending. Reception triggers remote wakeup.
The last busy facility of the USB autosuspend code is used. To close
a race between autosuspend and transmission, a counter of ongoing
transmissions is maintained.
Add #ifdefs for CONFIG_PM as necessary.

The NETPOLL API requires that interrupts remain disabled in
netpoll_send_skb(). The use of "A functions set" in the NETPOLL API
callbacks causes the interrupts to get enabled and can lead to kernel
instability.
The solution is to use "B functions set" to prevent the irqs from
getting enabled while in netpoll_send_skb().
A functions set:
local_irq_disable()/local_irq_enable()
spin_lock_irq()/spin_unlock_irq()
spin_trylock_irq()/spin_unlock_irq()
B functions set:
local_irq_save()/local_irq_restore()
spin_lock_irqsave()/spin_unlock_irqrestore()
