ixgbevf: Mailbox improvements

Improve reliability of the mailbox communication and remove
its potential flaws that may lead to the undefined or faulty behavior.

Recently some users reported issues on ESX with 10G Intel NICs which were
found to be caused by incorrect implementation of the PF-VF mailbox
communication.

Technical investigation highlighted areas to improve in the communication
between PF or VF that wants to send the message (sender) and the other
part which receives the message (receiver):

- Locking the mailbox when the sender wants to send a message
- Releasing the mailbox when the communication ends
- Returning the result of the mailbox message execution

net/intel: remove driver versions from Intel drivers

As with other networking drivers, remove the unnecessary driver version
from the Intel drivers. The ethtool driver information and module version
will then report the kernel version instead.

For ixgbe, i40e and ice drivers, the driver passes the driver version to
the firmware to confirm that we are up and running. So we now pass the
value of UTS_RELEASE to the firmware. This adminq call is required per
the HAS document. The Device then sends an indication to the BMC that the
PF driver is present. This is done using Host NC Driver Status Indication
in NC-SI Get Link command or via the Host Network Controller Driver Status
Change AEN.

What the BMC may do with this information is implementation-dependent, but
this is a standard NC-SI 1.1 command we honor per the HAS.

ixgbe/ixgbevf: fix XFRM_ALGO dependency

Based on the original work from Arnd Bergmann.

When XFRM_ALGO is not enabled, the new ixgbe IPsec code produces a
link error:

drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.o: In function `ixgbe_ipsec_vf_add_sa':
ixgbe_ipsec.c:(.text+0x1266): undefined reference to `xfrm_aead_get_byname'

Simply selecting XFRM_ALGO from here causes circular dependencies, so
to fix it, we probably want this slightly more complex solution that is
similar to what other drivers with XFRM offload do:

A separate Kconfig symbol now controls whether we include the IPsec
offload code. To keep the old behavior, this is left as 'default y'. The
dependency in XFRM_OFFLOAD still causes a circular dependency but is
not actually needed because this symbol is not user visible, so removing
that dependency on top makes it all work.

ixgbevf: Fix coexistence of malicious driver detection with XDP

In the case of the VF driver it is supposed to provide a context descriptor
that allows us to provide information about the header offsets inside of
the frame. However in the case of XDP we don't really have any of that
information since the data is minimally processed. As a result we were
seeing malicious driver detection (MDD) events being triggered when the PF
had that functionality enabled.

To address this I have added a bit of new code that will "prime" the XDP
ring by providing one context descriptor that assumes the minimal setup of
an Ethernet frame which is an L2 header length of 14. With just that we can
provide enough information to make the hardware happy so that we don't
trigger MDD events.

ixgbevf: Add support for XDP_TX action

This implements the XDP_TX action which is modeled on the ixgbe
implementation. However instead of using CPU id to determine which XDP
queue to use, this uses the received RX queue index, which is similar
to i40e. Doing this eliminates the restriction that number of CPUs not
exceed number of XDP queues that ixgbe has.

Also, based on the number of queues available, the number of TX queues
may be reduced when an XDP program is loaded in order to accommodate the
XDP queues.

Update the driver code so that we do bulk updates of the page reference
count instead of just incrementing it by one reference at a time. The
advantage to doing this is that we cut down on atomic operations and
this in turn should give us a slight improvement in cycles per packet.
In addition if we eventually move this over to using build_skb the gains
will be more noticeable.
