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.

Recent firmware revisions have added the ability to force
these modems to USB2 mode, hiding their SuperSpeed
capabilities from the host. The driver has been using the
SuperSpeed capability, as shown by the bcdUSB field of the
device descriptor, to detect the need to enable the DTR
quirk. This method fails when the modems are forced to
USB2 mode by the modem firmware.
Fix by unconditionally enabling the DTR quirk for the
affected device IDs.

On some boards a platform clock is used as clock for the r8169 chip,
this commit adds support for getting and enabling this clock (assuming
it has an "ether_clk" alias set on it).
This is related to commit d31fd43c0f ("clk: x86: Do not gate clocks
enabled by the firmware") which is a previous attempt to fix this for some
x86 boards, but this causes all Cherry Trail SoC using boards to not reach
there lowest power states when suspending.
This commit (together with an atom-pmc-clk driver commit adding the alias)
fixes things properly by making the r8169 get the clock and enable it when
it needs it.

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:

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.

Net drivers using phylink shouldn't mess with the link carrier
themselves and should let phylink manage it. The mvpp2 driver wasn't
following this best practice as the mac_config() function made calls to
change the link carrier state. This led to wrongly reported carrier link
state which then triggered other issues. This patch fixes this
behaviour.
But the PPv2 driver relied on this misbehaviour in two cases: for fixed
links and when not using phylink (ACPI mode). The later was fixed by
adding an explicit call to link_up(), which when the ACPI mode will use
phylink should be removed.
The fixed link case was relying on the mac_config() function to set the
link up, as we found an issue in phylink_start() which assumes the
carrier is off. If not, the link_up() function is never called. To fix
this, a call to netif_carrier_off() is added just before phylink_start()
so that we do not introduce a regression in the driver.
