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 introduces the callback to the ndo_setup_tc function
in the VF driver. We add a wrapper function to make room for the
upcoming cloud filter patches which add calls to different functions
from setup_tc.

First, we add support for capability exchange for ADQ between the
PF and VF. Next, we add support to take in the mqprio configuration
and configure queues as per the traffic classes, rate limit and the
priorities specified by the user. This is done by passing the channel
config to the PF driver through a virtchannel message.

The flags and bits added, track if ADq is enabled, set max number of
traffic classes to 4 and provide ability to negotiate capability with
the PF.

While testing code for the recent ITR changes I found that updating the Tx
ITR appeared to have no effect with everything defaulting to the Rx ITR. A
bit of digging narrowed it down the fact that we were asking the PF to
associate all causes with ITR 0 as we weren't populating the itr_idx values
for either Rx or Tx.

To correct it I have added the configuration for these values to this
patch. In addition I did some minor clean-up to just add a local pointer
for the vector map instead of dereferencing it based off of the index
repeatedly. In my opinion this makes the resultant code a bit more readable
and saves us a few characters.

Stop overloading the __I40EVF_IN_CRITICAL_TASK bit lock to protect the
mac_filter_list and vlan_filter_list. Instead, implement a spinlock to
protect these two lists, similar to how we protect the hash in the i40e
PF code.

Ensure that every place where we access the list uses the spinlock to
ensure consistency, and stop holding the critical section around blocks
of code which only need access to the macvlan filter lists.

This refactor helps simplify the locking behavior, and is necessary as
a future refactor to the __I40EVF_IN_CRITICAL_TASK would cause
a deadlock otherwise.

When using 'ethtool -L' on a VF to change number of requested queues
from PF, we shouldn't trust the VF to reset itself after making the
request.  Doing it that way opens the door for a potentially malicious
VF to do nasty things to the PF which should never be the case.

This makes it such that after VF makes a successful request, PF will
then reset the VF to institute required changes.  Only if the request
fails will PF send a message back to VF letting it know the request was
unsuccessful.

Testing-hints:
There should be no real functional changes.  This is simply hardening
against a potentially malicious VF.

Currently the VF gets a default number of allocated queues from HW on
init and it could choose to enable or disable those allocated queues.
This makes it such that the VF can request more or less underlying
allocated queues from the PF.

First the VF negotiates the number of queues it wants that can be
supported by the PF and if successful asks for a reset.  During reset
the PF will reallocate the HW queues for the VF and will then remap the
new queues.

Currently i40evf_close() can return before state transitions to
__I40EVF_DOWN because of the latency involved in processing and
receiving response from PF driver and scheduling of VF watchdog_task.
Due to this inconsistency an immediate call to i40evf_open() fails
because state is still DOWN_PENDING.

When a VF interface is in up state and we try to add it as slave,
The bonding driver calls dev_close() and dev_open() in short duration
resulting in dev_open returning error. The ifenslave command needs
to be run again for dev_open to succeed.

This fix ensures that watchdog timer is scheduled immediately after
admin queue operations are scheduled in i40evf_down(). In addition a
wait condition is added at the end of i40evf_close so that function
wont return when state is still DOWN_PENDING. The timeout value is
chosen after some profiling and includes some buffer.

This patch adds a capability negotiation between VF and PF using ENCAP/
ENCAP_CSUM offload flags in order for the VF to support outer checksum

by default and enabled in current hardware. Going forward, these features
needs to be negotiated with PF before advertising to the stack.
Additionally, strip out the mac.type checks for X722 since outer checksums
are enabled based on the ENCAP_CSUM offload negotiation flag and maintain
consistency between drivers in how the features are configured.

This patch changes the way we handle the maximum frame size for the Rx
path.  Previously we were rounding up to 2K for a 1500 MTU and then brining
the max frame size down to MTU plus a fixed amount.  With this patch
applied what we now do is limit the maximum frame to 1.5K minus the value
for NET_IP_ALIGN for standard MTU, and for any MTU greater than 1500 we
allow up to the maximum frame size.  This makes the behavior more
consistent with the other drivers such as igb which had similar logic.  In
addition it reduces the test matrix for MTU since we only have two max
frame sizes that are handled for Rx now.

In preparation for upcoming RDMA-capable hardware, add a client
interface to the VF driver. This is a slightly-simplified version
of the PF client interface, with the names changed to protect the
innocent.

Due to the nature of the VF<->PF interactions, the client interface
sometimes needs to call back into itself to pass messages. Because
of this, we can't use the coarse-grained locking like the PF's
client interface uses. Instead, we handle all client interactions
in a separate thread so the watchdog can still run and process
virtual channel messages.

If the user adds an obscene amount of MAC addresses, the driver will run
into the situation where it has too many address requests to fit into a
single PF message. The driver checks for this case, and calculates the
maximum number of messages that it can send. Then it completely ignores
this count and overflows the buffer.

Fix this by checking the address count and bailing out of the loop at
the appropriate time.
