E5372 with different product IDs.
Interestingly, the standard E5372 IDs (12d1:1506) are currently listed in
u3g.c and are the same as the E3131. However, the R215/E5372 is an NCM
device and works well with cdce(4) whereas the E3131 isn't. More work
may be needed to better identify the other device IDs.

This gets rid of the following error message during FreeBSD guest bootup:

FreeBSD has ARC_BUFC_NUMMETADATALISTS metadata lists and ARC_BUFC_NUMDATALISTS
data lists (currently both are 16) while illumos has just a single list
of each kind.
headroom determines how much data is scanned on a single list
during each run of the l2arc feed thread.
Because FreeBSD has more lists we proportionally decrease the limit.

configuration value is an integer count of seconds, it is not a timeval.

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.

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.

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().

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.
