Rename the Intel Ethernet Adaptive Virtual Function driver
(i40evf) to a new name (iavf) that is more consistent with
the ongoing maintenance of the driver as the universal VF driver
for multiple product lines.
This first patch fixes up the directory names and the .ko name,
intentionally ignoring the function names inside the driver
for now. Basically this is the simplest patch that gets
the rename done and will be followed by other patches that
rename the internal functions.
This patch also addresses a couple of string/name issues
and updates the Copyright year.
Also, made sure to add a MODULE_ALIAS to the old name.

This patch fixes skb_shared area, which will be corrupted
upon reception of 4K jumbo packets.
Originally build_skb usage purpose was to reuse page for skb to eliminate
needs of extra fragments. But that logic does not take into account that
skb_shared_info should be reserved at the end of skb data area.
In case packet data consumes all the page (4K), skb_shinfo location
overflows the page. As a consequence, __build_skb zeroed shinfo data above
the allocated page, corrupting next page.
The issue is rarely seen in real life because jumbo are normally larger
than 4K and that causes another code path to trigger.
But it 100% reproducible with simple scapy packet, like:
sendp(IP(dst="192.168.100.3") / TCP(dport=443) \

The switch and the MAC are in one IP core and they use the same clock
signal from the clock generation unit.
Currently the clock architecture in the lantiq SoC code does not allow
to easily share the same clocks, this has to be fixed by switching to
the common clock framework.
As a workaround the clock of the switch and MAC should be activated when
the MAC gets probed and only disabled when the MAC gets removed. This
way it is ensured that the clock is always enabled when the switch or
MAC is used. The switch can not be used without the MAC.
This fixes a data bus error when rebooting the system and deactivating
the switch and mac and later accessing some registers in the cleanup
while the clocks are disabled.

This adds the DSA driver for the GSWIP Switch found in the VRX200 SoC.
This switch is integrated in the DSL SoC, this SoC uses a GSWIP version
2.1, there are other SoCs using different versions of this IP block, but
this driver was only tested with the version found in the VRX200.
Currently only the basic features are implemented which will forward all
packages to the CPU and let the CPU do the forwarding. The hardware also
support Layer 2 offloading which is not yet implemented in this driver.
The GPHY FW loaded is now done by this driver and not any more by the
separate driver in drivers/soc/lantiq/gphy.c, I will remove this driver
is a separate patch. to make use of the GPHY this switch driver is
needed anyway. Other SoCs have more embedded GPHYs so this driver should
support a variable number of GPHYs. After the firmware was loaded the
GPHY can be probed on the MDIO bus and it behaves like an external GPHY,
without the firmware it can not be probed on the MDIO bus.
The clock names in the sysctrl.c file have to be changed because the
clocks are now used by a different driver. This should be cleaned up and
a real common clock driver should provide the clocks instead.

This drives the PMAC between the GSWIP Switch and the CPU in the VRX200
SoC. This is currently only the very basic version of the Ethernet
driver.
When the DMA channel is activated we receive some packets which were
send to the SoC while it was still in U-Boot, these packets have the
wrong header. Resetting the IP cores did not work so we read out the
extra packets at the beginning and discard them.
This also adapts the clock code in sysctrl.c to use the default name of
the device node so that the driver gets the correct clock. sysctrl.c
should be replaced with a proper common clock driver later.
