Regression introduced in r343629 when malloc result was renamed from spa to
spa_mapping and the 'spa' name was instead used to iterate a table, but the
free() target was not updated.

The PRM suggests random 0 - 10ms to prevent multiple waiters on the same
interval in order to avoid starvation.

Before attempting to initialize the command interface we must wait till
the fw_initializing bit is clear.
If we fail to meet this condition the hardware will drop our
configuration, specifically the descriptors page address. This scenario
can happen when the firmware is still executing an FLR flow and did not
finish yet so the driver needs to wait for that to finish.

It may happen during link down that the running state may be observed
non-zero in the transmit routine, right before the running state is
cleared. This may end up using a destroyed mutex.
Make all channel mutexes and callouts persistant.
Preserve receive and send queue statistics during link toggle.

In case of health counter fails to increment it indicates a bad device health.
In case when the syndrome indicated by firmware is 0x0, this indicates that
firmware is unable to respond to initialization segment reads.
Add proper print in this case.

MPFS is a logical switch in the Mellanox device which forward packets
based on a hardware driven L2 address table, to one or more physical-
or virtual- functions. The physical- or virtual- function is required
to tell the MPFS by using the MPFS firmware commands, which unicast
MAC addresses it is requesting from the physical port's traffic.
Broadcast and multicast traffic however, is copied to all listening
physical- and virtual- functions and does not need a rule in the MPFS
switching table.

Currently only suspend requests are acknowledged by writing an empty
string back to the xenstore control node, but poweroff or reboot
requests are not acknowledged and FreeBSD simply proceeds to perform
the desired action.
Fix this by acknowledging all requests, and remove the suspend specific
ack done in the handler.

As of r347221 the iflib legacy interrupt mode setup assumes that drivers
perform both receive and transmit processing from the interrupt handler.
This assumption is invalid in the vmxnet3 driver, so introduce the
IFLIB_SINGLE_IRQ_RX_ONLY flag to make iflib avoid tx processing in the
interrupt handler.

r347183 bumped GEOM classes to SI_ORDER_SECOND to resolve a race between
them and the initialization of devsoftc.mtx in devinit, but missed this
dependency on g_flashmap that may now lose the race against GEOM
classes/g_init.
There's a great comment that describes the situation that has also been
updated with the new ordering of GEOM classes.
