The patch is to add support for MCDI proxy which comes in
useful, particularly, while running over VF: few commands
will normally fail with EPERM, but in some cases the host
driver (i.e. running over the corresponding PF, typically,
within a hypervisor) may set itself as a proxy to conduct
authorization for the commands coming from VFs; these are
forwarded to the corresponding access control application
which may decline or approve authorization by replying to
the requests; all in all, the guest driver has to process
the replies forwarded back by the firmware MC in order to
give up gracefully (by setting return code which could be
understood by 'libefx') or re-issue the original commands

This commit adds a signal-based trigger to the Rx burst function in order
to avoid unnecessary system calls while Rx queues are empty.
Triggered Rx bursts put less pressure on the kernel, free up CPU resources
for applications and result in a noticeable performance improvement when
sharing CPU threads with other PMDs.
Measuring the traffic forwarding rate between two physical devices in
testpmd (IO mode, single thread, 64B packets) before and after adding two
tap PMD instances (4 ports total) that do not process any traffic and
comparing results yields:
Without Rx trigger:
-15% (--burst=32)
-62% (--burst=1)
With Rx trigger:
-0.3% (--burst=32)
-6% (--burst=1)

The hardware offload capabilities are not being advertised for the EM PMD.
Because of this, applications that only enable these features if the device
advertises them will never do so.
Normally this is not an issue since normal packet processing should work
even if hardware offload is not available. But, in older versions of
Virtual Box the e1000 device emulation (Intel PRO/1000 MT Desktop 82540EM)
assumes that it should enable VLAN stripping even if the driver does not
request it. This means that any ingress packets that have a VLAN tag will
be stripped. Since the application did not request to enable VLAN
stripping it is not expecting these packets so they are not processed as
VLAN packets.
Regardless of the Virtual Box issue, the driver should be advertising
supported capabilities as is done in other drivers.

The previous API had various problems, including the length of the
caller provided buffer not being specified, no means being available
to discover how big the buffer needs to be, and a lack of clarity of
what the resulting list contains.
To improve it:
- add the buffer length as a parameter
- if the provided buffer is too short, fail with ENOSPC and return
the required length
- ensure that the list contents are valid and add comments describing it
It is safe to change this API as, unsurprisingly, it has no users.

The flag EFX_FILTER_MATCH_LOC_MAC_IG to represent filtering on the
individual/group bit of the MAC address (with the two cases being
distinguished by the MAC address in the filter specification) was
introduced to mirror the Linux driver filtering code, but the
implementations are different enough anyway that it isn't of much
value.
Having separate flags for unknown unicast and multicast simplifies
the code and allows the set of flags to match those used by MCDI.
It will also makes it easier to report whether these filters are
supported.
In the MCDI definitions, the unknown multicast and unicast flags
have the values 0x40000000 and 0x80000000 respectively, and so using
the same values for simplicity requires 32 bits in the filter
specification to store the flags. This means the structure is now
a little bigger than 64 bytes, but filters are not often used on
critical paths so this shouldn't have much impact - on Linux they
are also bigger than they used to be.

Multiple IES API resets can cause a race condition where the mailbox
interrupt request bits can be cleared before being handled. This can
leave certain mailbox messages from the PF to be untreated and the PF
will enter in some inactive state. If this situation occurs, the IES API
will initiate a mailbox version reset which, then, trigger a mailbox
state change. Once this mailbox transition occurs (from OPEN to CONNECT
state), a request for reset will be returned.

Don't report FM10K_ERR_REQUESTS_PENDING when we fail to disable queues
within the timeout. This can occur due to a hardware Tx hang, or when
the switch ethernet fabric is resetting while we are transmitting
traffic. It can sometimes take up to 500ms before the Tx DMA engine
gives up. Instead, just skip the DMA engine check and perform
a data-path reset anyways. Add a statistic counter to keep track of the
number of resets occurring while we have pending DMA on the rings.
In order to prevent having to assign err = FM10K_SUCCESS, re-order the
last few items of the reset_hw_pf function so that we don't perform
"return err" at the end.

If the fm10k interface is brought up, but the switch manager software is
not running, the driver will continuously request the lport map every
few seconds in the base driver watchdog routine. Eventually after

reason, and occurs regularly every few minutes until the switch manager

The VF uses a multi-bit update request to clear unused VLANs whenever it
resets. However, an accident in a previous refactor broke multi-bit
updates for VFs, due to misreading a comment in fm10k_vf.c and
attempting to reduce code duplication. The problem occurs because
a multi-bit request has a non-zero length, and the PF would simply drop
any request with the upper 16 bits set. In addition, a multi-bit vlan
update does not have a concept for "VLAN 0" as the single bit update
does.
A previous revision of this patch resolved the issue by simply removing
the upper 16 bit check and the iov_select_vid checks. However, this would
remove the checks for default VID and for ensuring no other VLANs can be
enabled except pf_vid when it has been set. To resolve that issue, this
revision uses the iov_select_vid when we have a single-bit update, and
denies any multi-bit update when the VLAN was administratively set by
the PF. This should be ok since the PF properly updates VLAN_TABLE when
it assigns the PF vid. This ensures that requests to add or "remove" the
PF vid work as expected, but a rogue VF could not use the multi-bit
update as a loophole to attempt receiving traffic on other VLANs.
