It is unclear why this hasn't bothered anyone in months; I can only assume
optimization levels but it seems there were unresolved symbols in
iwlwifi after d9836fb4b9:
link_elf_obj: symbol iwl_mvm_send_roaming_forbidden_event undefined
Hide more of the currently unsupported (GPL-only) MEI (Management Engine)
code behind #ifdef to avoid this.

By analogy with IP address matching, add a way to use ipfw radix
tables for MAC matching. This is implemented using new ipfw table
with mac:radix type. Also there are src-mac and dst-mac lookup
commands added.
Usage example:
ipfw table 1 create type mac
ipfw table 1 add 11:22:33:44:55:66/48
ipfw add skipto tablearg src-mac 'table(1)'
ipfw add deny src-mac 'table(1, 100)'
ipfw add deny lookup dst-mac 1
Note: sysctl net.link.ether.ipfw=1 should be set to enable ipfw
filtering on L2.

When a state if pfsync’d to a different host it doesn’t get all of the
expected pointers, including the pointer to the struct pfi_kif / struct
ifnet rt_kif pointer. (I.e. the interface to route out on).
That in turn means that pf_route() ends up dropping the packet.
Use the rule's struct pfi_kif pointer so we can still route out of the
expected interface.

Add a FreeBSD-specifc SYSCTL_PROC to dump the list of
PCI IDs / name / firmware-prefix which can be post-processed
for man pages (iwlwifi.4 and iwlwififw.4) or the wiki.
The output still yields duplicates depending on by what information
you need so one may wants to filter them out (try not to use sort/uniq).

Linux has two defines to check dmi data. DMI_MATCH checks if the dmi
string includes substr. DMI_EXACT_MATCH checks if the dmi string exactly
matches substr. Compat layer should have the same behaviour.
The new definition of dmi_strmatch shouldn't break any driver. A driver
would break if it uses the highest bit of the slot field. Nevertheless,
linux uses the same definition and FreeBSD uses dmi_field values as slot
which are lower than 128.

When the TCP sequence number subtracted is greater than 2**32 minus
the window size, or 2**31 minus the window size, the use of unsigned
long as an intermediate variable, may result in an incorrect retransmit
length computation on all 64-bit platforms.
While at it create a helper macro to facilitate the computation of
the difference between two TCP sequence numbers.

After we wipe PMC configuration, including its local enable bit(s),
we don't really care about its global enable bit. Global enable bits
now may only be cleared by interrupt handler in case of error (sample
buffer overflow). Being set is actually a reset default for them.
This saves one WRMSR per process-scope PMC per context switch, that
is clearly visible in profiles.

When a NFSv4 byte range write lock is unlocked, all
data modifications need to be flushed to the server
to satisfy the coherency requirements for byte range
locking. However, if a write delegation for the
file is held by the client, flushing is not required,
since no other NFSv4 client can have the file NFSv4
Opened.
Found by inspection as suggested by a similar change
that was done to the Linux NFSv4 client.
Allocate memory for packed nvlists in M_NVLIST, as nvlist_pack() does
this as well, and we use the same variable interchangable with the
memory we allocate. When we free it we can end up freeing from the wrong
zone, leaking memory.

This is slightly more optimized than checking panicstr directly. For
most of these instances performance doesn't matter, but let's make
KERNEL_PANICKED() the common idiom.
