earlier. These workarounds are extensive and get in the way of understanding

Remove an old workaround that is no longer necessary since rS343824.
There used to be a problem with FMan interrupts firing on multiple CPUS
at the same time.
This ended up being due to multicast interrupts being unsupported in the
Freescale PIC (so instead of using a selection algorithm, it would do some
unspecified action, such as interrupting multiple cpus at random.)

When turning IBRS mitigation using sysctl, as opposed to loader tunable,
send IPI to tweak MSR on all cores. Right now code only performed MSR write
onr the CPU where sysctl was run.
Properly report hw.ibrs_active for IBRS_ALL. Split hw_ibrs_ibpb_active out
from ibrs_active, to keep the current semantic of guiding kernel entry and

commands have completed.
It's not OK to force complete any pending commands before we send the
REMOVE_DEVICE. Instead, make sure that all pending commands are complete before
sending that. By trying to second guess the firmware here, we run the risk of
completing commands twice, which leads to corruption.
This removes the forced completion of commands introduced in r218811. So it's a
partial backout of that commit, but replaces it with a more rebust
mechanism. Either these commands will complete due to the TARGET RESET, or they
will timeout and be aborted, but they will all complete.
Add assert that all commands are complete to REMOVE_DEVICE completion
routine. We attempt to assure this programatically, so we shouldn't have any
commands in the queue because we've waited for them all. Any commands that make
it into our action routine after we mark the target in removal will complete
immediately with an error.
When we're removing a target that's not a volume, advertise up the stack that
it's actually gone, as opposed to having a transient selection error we should
retry. Do this both in the action routine, and when we get a notification of an
aborted command. We don't do this for volumes because the driver tries hard not
to advertise to the OS a volume has disappeared.
Apply these changes to both mpr and mps since they are based on quite similar
designs.

After the network epoch was added, we lost the ability to migrate the
ithread in the middle of dispatch, as being in the network epoch will pin
the current thread (for safety reasons.)
Luckily, we don't actually have to do this workaround in the first place,
as we can just bind it to the correct cpu when we preallocate it.
Pass dev through to XX_PreallocAndBindIntr() and actually bind it to the
cpu like it was supposed to in the first place, instad of leaving it
floating and moving it to the correct cpu the first time it fires.
This fixes panics while bringing up dtsec on my X5000.

switch over to opt-in instead of opt-out for epoch.
Instead of IFF_NEEDSEPOCH, provide IFF_KNOWSEPOCH. If driver marks
itself with IFF_KNOWSEPOCH, then ether_input() would not enter epoch
when processing its packets.
Now this will create recursive entrance in epoch in >90% network
drivers, but will guarantee safeness of the transition.
Mark several tested drivers as IFF_KNOWSEPOCH.

Driver working in LLQ mode in some cases can send only few last segments
of the mbuf using DMA engine, and the rest of them are sent to the
device using direct PCI transaction. To map the only necessary data, two DMA
maps were used. That solution was very rough and was causing a bug - if
both maps were used (head_map and seg_map), there was a race in between
two flows on two queues and the device was receiving corrupted
data which could be further received on the other host if the Tx cksum
offload was enabled.
As it's ok to map whole mbuf and then send to the device only needed
segments, the design was simplified to use only single DMA map.
The driver version was updated to v2.1.1 as it's important bug fix.

When we register an interrupt handler we need to pass the intr_type along in

The interrupt type matters because it is used to decide if we need to enter
NET_EPOCH. That meant that vtmmio-based if_vtnet did not, which led to panics
with INVARIANTS set.
