a836c35229 ionic: protect vf calls from fw reset
When going into a firmware upgrade cycle, we set the device as
not present to keep some user commands from trying to change
the driver while we're only half there.  Unfortunately, the
ndo_vf_* calls don't check netif_device_present() so we need
to add a check in the callbacks.

5b3f3f2a71 ionic: support longer tx sg lists
The version 1 Tx queues can use longer SG lists than the
original version 0 queues, but we need to check to see if the
firmware supports the v1 Tx queues.  This implements the queue
type query for all queue types, and uses the information to
set up for using the longer Tx SG lists.

Because the Tx SG list can be longer, we need to limit the
max ring length to be sure we stay inside the boundaries of a
DMA allocation max size, so we lower the max Tx ring size.

The driver sets its highest known version in the Q_IDENTITY
command, and the FW returns the highest version that it knows,
bounded by the driver's version.  The negotiated version number
is later used in the Q_INIT commands.

c672412f61 ionic: remove lifs on fw reset
When the FW RESET event comes to the driver from the firmware,
or the fw_status goes to 0 (stopped) or to 0xff (no PCI
connection), then shut down the driver activity.  This event
signals a FW upgrade where we need to quiesce all operations and
wait for the FW to restart.  The FW will continue the update
process once it sees all the LIFs are reset.  When the update
process is done it will set the fw_status back to RUNNING.
Meanwhile, the heartbeat check continues and when the fw_status
is seen as set to running we can restart the driver operations.

49d3b49367 ionic: disable the queues on link down
When the link goes down, we need to disable the queues on the
NIC in addition to stopping the netdev stack.  This lets the
FW know that the driver has stopped queue activity, and then
the FW can do internal reconfiguration work, whether actually
Link related, or for other internal FW needs.  To do this,
we pull out the queue enable and disable from ionic_open()
and ionic_stop() so they can be used by other routines.

To help keep things sane, we swap the queue enables so that
the rx queue and its napi are enabled before the tx queue
which rides on the rx queues napi.

We also drop the ionic_lif_quiesce() as it doesn't do anything
more than what the queue disable has already taken care of.
