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.

The unlimited send tags are shared amount multiple connections and are
not allocated per send tag allocation request. Only increment the refcount.

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.

When the software send queue gets filled up, callbacks to
if_transmit will stop. Make sure the transmit callback
routine checks the send queue and outputs any remaining
mbufs. Else the remaining mbufs may simply sit in the
output queue blocking the transmit path.

The regexec function is declared as taking an array of regmatch_t
elements, and passing in the pointer to singleton element, while
correct, triggers a Coverity warning. Convert the singleton into
an array of one to silence the warning.

kern_shm_open2(), since conception, completely fails to pass the mode along
to kern_shm_open(). This breaks most uses of it.
Add tests alongside this that actually check the mode of the returned
files.

As is the current trend; while these files are manually curated, they are
still generated. If they end up in a review, it would be helpful to also
take the hint and hide them.
This commit add support for certctl in mergemaster and etcupdate. Both will
either rehash or prompt for rehash as new certificates are
trusted/blacklisted.

This is a simple utility to hash all trusted on the system into
/etc/ssl/certs. It also allows the user to blacklist certificates they do
not trust.
