Disable generating vfp and NEON instructions in the arm kernel.
Use r271207 optimization only for MSI-enabled HBAs.

It was found that VirtualBox' AHCI does not allow nterrupt to be cleared
before the interrupt status register is read, causing interrupt storm.

AHCI specification allows to skip this register use when multi-vector MSI
is enabled and so interrupting port is known.  For single-vector MSI that
is not stated explicitly, but if the port is only one, it is obviously
known too.
Improve "reserved keywords" hack:

we can't easily predict (in current parsing model)
if the keyword is ipfw(8) reserved keyword or port name.
Checking proto database via getprotobyname() consumes a lot of
CPU and leads to tens of seconds for parsing large ruleset.
Use list of reserved keywords and check them as pre-requisite
before doing getprotobyname().

Fix O_TCPOPTS processing.

Add support for MaxBurstLength and Expected Data transfer Length parameters.

Before this change target could send R2T request for write transfer of any
size, that could violate iSCSI RFC, which allows initiator to limit maximum
R2T size by negotiating MaxBurstLength connection parameter.

Also report an error in case of write underflow, when initiator provides
less data than initiator expects.  Previously in such case our target
sent R2T request for non-existing data, violating the RFC, and confusing
some initiators.  SCSI specs don't explicitly define how write underflows
should be handled and there are different oppinions, but reporting error
is hopefully better then violating iSCSI RFC with unpredictable results.

 use calloc in get_line() when allocating line to ensure it is fully initialized,
 fixes a later uninitialized value in copy_param() (FreeBSD #193499).

Call initializecpucache() on the BSP for i386 in the !XEN case.  This was
my bug in r271409 that I noticed while reviewing r272492.
Add netmap support to libpcap. Tcpdump and other native pcap application can now
run directly on netmap ports using netmap:foo or valeXX:YY device names.
Modifications to existing code are small and trivial, the netmap-specific
code is all in a new file.

Please be aware that in netmap mode the physical interface is disconnected from
the host stack, so libpcap will steal the traffic not just make a copy.

For the full version of the code (including linux and autotools support) see

Properly set the timeout in a query_state.  The global query_timeout
configuration value is an integer count of seconds, it is not a timeval.
Using memcpy() to copy a timeval from it put garbage into the tv_usec

Inject #UD into the guest when it executes either 'MONITOR' or 'MWAIT'.

The hypervisor hides the MONITOR/MWAIT capability by unconditionally setting
CPUID.01H:ECX[3] to 0 so the guest should not expect these instructions to
be present anyways.

Treat D keywords as identifiers in certain postfix expressions. This allows
one to, for example, access the "provider" field of a struct g_consumer,
even though "provider" is a D keyword.
