Ping used to provide some sort of packet sniffing capabilities, this was
in an era where hubs were used and tcpdump wasn't invented.
pr_iph() is a function that prints the IP header of the packet.
pr_retip() is essentially a wrapper function to pr_iph(), that also
displays the source and destination ports of a TCP or UDP packet.
After ef9e6dc7ee some of this
functionality was almost removed, to only display packets sent by us
(26+ years ago).
At this point, reaching this code path was only possible by doctoring
the original packet.
After 46d7b45a26 this code path can never
be reached.
Remove the code.

When an ICMP packet contains an IP packet in its payload, and that
original IP packet contains options, these options were not displayed
accordingly in pr_iph().
pr_iph() is a function that prints the original "quoted packet" IP
header, with only an IP struct as an argument. The IP struct does not
contain IP options, and it is not guaranteed that the options will be
contiguous in memory to the IP struct after
d9cacf605e.
Pass the raw ICMP data along with the IP struct, in order to print the
options, if any.

Revision r333125 AKA 986c4ca387 forced clear cpu_stdext_feature3
on suspend, since at that time microcode update was not reloaded
early on resume. Then, revision 050f5a8405 started re-reading
cpu_stdext_feature3 again. Since modern CPUs do not require mitigations
from the Skylake era, this went unnoticed for some time.
Keep zeroing cpu_stdext_feature3 on suspend, but re-read it in more
controlled way on resume after microcode is reloaded, and recalculate
active workarounds based on actual microcode capabilities.

Azure setup does not like it when FreeBSD overrides the settings of the
UART device. When Hyper-V is detected, don't do this and also don't
throttle putc() output. This is a workaround for the early boot hang

UEFI provides ConIn/ConOut handles for consoles that it supports,
which include the text-video and serial ports. When the serial port
is available, use the UEFI driver instead of direct io-port accesses
to avoid conflicts between the firmware and direct hardware access, as
happens on Hyper-V (Azure) setups.
This change enables efiserialio to be built for efi-amd64 and has
higher order priority vs comconsole, and only uses efiserialio
if the hypervisor is Hyper-V. When efiserialio successfully
probes, it will set efi_comconsole_avail=true which will prevent
comconsole from probing in this setup.
Tested on Hyper-V, ESXi and Azure VMs.

Bracket the kern.vnode sysctl in #ifdef notyet because it results

It is also not clear that this sysctl is non-dangerous in its

ipi counters are missing in bhyvectl's output because vm_maxcpu is 0
when initializing them. That's because vmm_stat_register is executed
before vmm_init.
Instead of directly fixing it, there's a better solution in illumos
which is cherry picked:
65a3bc8373
It replaces the matrix statistic by two counters per vcpu. One for
counting the ipis to the vcpu and one counting the ipis received by the
vcpu. This has several advantages:
- A matrix statistic becomes huge when using many vcpus.
- A matrix statistic easily reaches the MAX_VMM_STAT_ELEMS limit.
- Two counters are enough in most cases. DTrace can be used for more
advanced debugging purposes.
- A matrix statistic wastes memory. The matrix size is determined by
vm_maxcpu regardless of the number of vcpus assigned to the vm.
