Do not publish a running interface after vnic_dev_enable_wait() fails.
Run the existing stop cleanup for the queues configured before the enable
request, then report initialization failure to iflib.
Mark those queues as needing cleanup before submitting the enable request
so the stopped-state shortcut cannot skip the unwind.

The transmit stop loop cleaned the receive completion ring, and the
receive stop loop cleaned the transmit completion ring. Use enic_cq_wq()
for transmit queues and enic_cq_rq() for receive queues, matching the
queue indices used by the remaining ring bookkeeping.

Replace direct IFF_DRV_RUNNING reads in igbv, ixgbe, ixv, iavf, ixl,
ice, bnxt Ethernet, aq, enic and the axgbe PCI frontend with
iflib_is_running(). Keep each existing mailbox-ready, fault-state,
link-state and administrative-up condition: framework admission is not
a substitute for device specific readiness.
This covers interrupt admission, operational link publication, VF
mailbox and VLAN replay, and live-configuration decisions. Remove
ifnet temporaries used only to read the driver flags.
Replace the em and igc debug dumps' RUNNING/OACTIVE text with one
framework admission snapshot. OACTIVE does not mean that the interface
or hardware is inactive. Label the result as software admission rather
than link state or proof that DMA has stopped, and retain the queue
head/tail dumps and separate RS diagnostics. Keep the filter register
and requested interface flags in the axgbe PCI promiscuous-mode trace,
but remove its unrelated legacy driver flags.
Use the parent Ethernet PF context for the bnxt RDMA running check,
retaining the link-state check and the existing IB_PORT_ACTIVE policy.
Both current RDMA construction paths use the PF netdev, and Ethernet
detach synchronously removes the RDMA auxiliary child before iflib frees
that context. Declare the direct iflib module dependency. This does
not transfer ownership of RDMA queues to iflib.
Leave the independent, non-iflib axgbe ARM frontend unchanged.

Mark the driver stopped after attach so its first IFDI_STOP() call
does not repeat hardware shutdown.
Defer error interrupt recovery through iflib instead of calling
driver stop and init methods from interrupt context. Let iflib own
the stop and restart around MTU changes as well, avoiding duplicate
lifecycle operations.

Completion queues are allocated by attach_pre but released by
queues_free. An iflib failure between those stages leaks the allocation,
while the original size expression also underallocates the array.
Move completion queue allocation into the TX queue callback, correct its
size, and unwind it with TX state if RX allocation fails. Make interrupt
cleanup tolerate an unavailable array and reuse the array allocated
during device initialization instead of replacing and leaking it.
Release the DMA, multicast, and lock resources owned by a successful
attach_pre during detach. Avoid allocating the statistics DMA area a
second time near the end of attach_pre.

For safety I was trying to clear out the descriptor but the full descriptor
was not allocated. Remove any code trying to do that so the same mistake
won't be made. This was found when looking to MFC the prior change
and having the loader, load the module.
Remove cq->ntxqsets since the completion queue is part of the RX and TX sets

ifconfig down/up cycles was not working. Fix that which is required
to support MTU changes. Now doing ifconfig enic0 mtu 3000 for example
works. If the MTU is changes in the VIC HW configuration, that is not
reflected in and the OS reports the default 1500. I need to look at
that but changing it via ifconfig works. So this is different then
what Linux does.
Change TX interrupt allocation to be in this driver. Change the admin
interrupt count to 2. This make multiple queues work but need to be
done as pairs so if the VIC has more TX or RX queues setup in the
VIC configuration it will use the lesser value.
While updating the TX interrupt also add support for devcmd2.
Enable checksum offloading.

In rS360398, a new iflib device method was added with default of opt out
for VLAN events needing an interface reset.
This re-init is unintentional for vmxnet3(4).

Since d49e83eac3baf16a22b1c5d42e8438b68b17e6f9, iflib(9) is ready
for this change.
While at it, make isc_driver_version strings (static) const where
not apparently un-const on purpose, too.
This reduces the size of the amd64 GENERIC by about 10 KiB.

This driver is based of the enic (Cisco VIC) DPDK driver. It provides
basic ethernet functionality. Has been run with various VIC cards to
do UEFI PXE boot with NFS root.
