* Don't reset the entire adapter for vlan changes, fix up the problems
* Add some functions for vlan filter (vfta) manipulation
* Don't muck with the vfta if we aren't doing HW vlan filtering
* Disable interrupts when manipulating vfta on lem(4)-class NICs
* On the I350 there is a specification update (2.4.20) in which the
suggested workaround is to write to the vfta 10 times (if at first you
don't succeed, try, try again). Our shared code has the goods, use it
* Increase a VF's frame receive size in the case of vlans
From the referenced PR, this reduced vlan configuration from minutes
to seconds with hundreds or thousands of vlans and prevents wedging the
adapter with needless adapter reinitialization for each vlan ID.

By default, this is never set when RXCSUM is disabled - which

* Fix 82574 Link Status Changes, carrying the OTHER mask bit around as
needed.
* Move igb-class LSC re-arming out of FAST back into the handler.
* Clarify spurious/other interrupt re-arms in FAST.
In MSI-X mode, 82574 and igb-class devices use an interrupt filter to
handle Link Status Changes. We want to do LSC re-arms in the handler
to take advantage of autoclear (EIAC) single shot behavior.
82574 uses 'Other' in ICR and IMS for LSC interrupt types when in MSI-X
mode, so we need to set and re-arm the 'Other' bit during attach and
after ICR reads in the FAST handler if not an LSC or after handling on
LSC due to autoclearing.
This work was primarily done to address the referenced PR, but inspired
some clarification and improvement for igb-class devices once the
intentions of previous bug fix attempts became clearer.

This structure is shared among multiple instances of a driver, so we

separate instance per interface. This is especially important for
software-only drivers like wg.
DEVICE_REGISTER() still returns a void * and so the per-driver sctx
structures are not yet defined with the const qualifier.

Memory and PCI resources are freed with no particular order. This could
cause use-after-frees when detaching following a failed attach. For
instance, iflib_tx_structures_free() frees ctx->ifc_txqs[] but
iflib_tqg_detach() attempts to access this array. Similarly, adapter
queues gets freed by IFDI_QUEUES_FREE() but IFDI_DETACH() attempts to
access adapter queues to free PCI resources.

It's rather confusing when adapter->hw and hw are mixed and matched
within a particular function.
Some of this was missed in cd1cf2fc1d
and r353778 respectively.
Current way, hardcoded value plus heuristic is not conform to the PCI(e)
specification and it fails on systems where MSI-X bar is not initialized by
BIOS/ACPI (many arm or arm64 systems for example).
Instead, use the standard PCI(e) capability for determining of
MSIX table bar address.

A failure in iflib_device_register() can result in
em_free_pci_resources() being called after receive queues have already
been freed. In particular, a failure to allocate IRQ resources will goto
fail_queues, where IFDI_QUEUES_FREE() will be called via
iflib_tx_structures_free(), preceding the call to IFDI_DETACH().
Cope with this by checking adapter->rx_queues before dereferencing it.
A similar check is present in ixgbe(4) and ixl(4).

Pursuant to r360398, implement driver-specific versions of the
ifdi_needs_restart iflib device method.
Some (if not most?) Intel network cards don't need reinitializing when a
VLAN is added or removed from the device hardware, so these implement
ifdi_needs_restart in a way that tell iflib not to bring the interface
up or down when a VLAN is added or removed, regardless of whether the
VLAN_HWFILTER interface capability flag is set or not.
This could potentially solve several PRs relating to link flaps that
occur when VLANs are added/removed to devices.
