of the TCP TS offset from taking the IP addresses and the TCP port
numbers into account to a version just taking only the IP addresses
into account. This works around broken middleboxes or endpoints.
The default is to keep the behaviour, which is also the behaviour
recommended in RFC 7323.

- Wrong order of casting and bit shift caused that enabling and disabling
queues didn't work properly for queues number larger than 32. Use literals
with right suffix instead.
- TX ring tail address was not updated during reinitiailzation of TX
structures. It could block sending traffic.
- Also remove unused variables 'eims' and 'active_queues'.

Previously only some of the ID register fields were 64 bit. To allow
for a script to generate these mark them all 64 bit. To allow for their
use in assembly we need to use the UINT64_C macro via a new UL macro
to stop the lines from being too long.

After r343631 pfil hooks are invoked in net_epoch_preempt section,
this allows to avoid extra locking. Add NET_EPOCH_ASSER() assertion
to each ipfw_bpf_*tap*() call to require to be called from inside
epoch section.
Use NET_EPOCH_WAIT() in ipfw_clone_destroy() to wait until it becomes
safe to free() ifnet. And use on-stack ifnet pointer in each
ipfw_bpf_*tap*() call to avoid NULL pointer dereference in case when
V_*log_if global variable will become NULL during ipfw_bpf_*tap*() call.

While for ATA disks resize is even more rare situation than for SCSI, it
may happen in case of HPA or AMA being used. Make ATA XPT report minor
IDENTIFY DATA change to upper layers with AC_GETDEV_CHANGED, and ada(4)
periph driver handle that event, recalculating all the disk properties and
signalling resize to GEOM. Since ATA has no mechanism of UNIT ATTENTIONs,
like SCSI, it has no way to detect that something has changed. That is why
this functionality depends on explicit reprobe via XPT_REPROBE_LUN call.

Summary:
Instead of searching for a PVO entry before adding, take advantage of
the fact that RB_INSERT() returns NULL if it inserts, and the existing entry if
an entry exists, without inserting a new entry. This saves an extra tree
traversal in the cases where the PVO does not exist.

we should test ATTR_SW_DBM, not ATTR_AP_RW, to determine whether to set

whether the dirty bit is preset, not whether the mapping is writeable.
