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.

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.

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.

the received packets, and pages are recycled as needed, or
left alone if they weren't used in the Rx.
