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.

the max can be hardcoded and a runtime test added for robustness.

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.

After system suspend, sometimes the r8169 doesn't work when ethernet
cable gets pluggued.
This issue happens because rtl_reset_work() doesn't get called from
rtl8169_runtime_resume(), after system suspend.
In rtl_task(), RTL_FLAG_TASK_* only gets cleared if this condition is
met:
if (!netif_running(dev) ||
!test_bit(RTL_FLAG_TASK_ENABLED, tp->wk.flags))
...
If RTL_FLAG_TASK_ENABLED was cleared during system suspend while
RTL_FLAG_TASK_RESET_PENDING was set, the next rtl_schedule_task() won't
schedule task as the flag is still there.
So in addition to clearing RTL_FLAG_TASK_ENABLED, also clears other
flags.
