The commit 3b57de958e brought the support for a different amount of the
filter bins, but didn't update the PCI driver accordingly. This patch appends
the default values when the device is enumerated via PCI bus.

Because bonding stats are usually sum of slave stats, it was
not easy to account for tx drops at bonding layer.
We can use dev->tx_dropped for this, as this counter is later
added to the device stats (in dev_get_stats())
This extends the idea we had in commit ee63771474 ("bonding: Simplify
the xmit function for modes that use xmit_hash") for bond_3ad_xor_xmit()
to other bonding modes.

With legacy booting, the platform init code was taking care of
the configuring of GPIOs. With device tree based booting, things
may or may not work depending what bootloader has configured or
if the legacy platform code gets called.
Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.
And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing
errors.

For Renesas USB 3.0 host controller, when unplugging the usb hub which

One of the problems with warm reset I've found is
that it must be guaranteed that copy engine

Instead of using sleeps and hoping the device is
operational in some arbitrary timeframes use
firmware indication register.

IPv6 does not allow fragmentation by routers, so there is no
fragmentation ID in the fixed header. UFO for IPv6 requires the ID to
be passed separately, but there is no provision for this in the virtio
net protocol.
Until recently our software implementation of UFO/IPv6 generated a new
ID, but this was a bug. Now we will use ID=0 for any UFO/IPv6 packet
passed through a tap, which is even worse.
Unfortunately there is no distinction between UFO/IPv4 and v6
features, so disable UFO on taps and virtio_net completely until we
have a proper solution.
We cannot depend on VM managers respecting the tap feature flags, so
keep accepting UFO packets but log a warning the first time we do
this.

Disconnect flow may be invoked either from upper layer request,
or from event reported by the firmware.
In case of firmware event, driver need to release resources for the station but
not send another disconnect WMI command.
In case of upper layer request, WMI_DISCONNECT_STA_CMDID command need to
be issued for the firmware to perform disconnect on the MAC layer. Eventually,
event is expected to confirm MAC disconnect, but it is better to not wait for
firmware event and release station resources immediately. FW may fail to
report disconnect for various reasons, so one could not rely on event always reported.
