regulatory domain with the "country" parameter, but will also take a full
country name. The man page warns that only the ISO code is unambiguous.
In reality, however, the first match on either would be accepted, leading
to "DE" being interpreted as the "DEBUG" country rather than Germany, and
"MO" selecting Morocco rather than the correct country, Macau.
Fix this by always checking for an ISO CC match first, and only search on
the full country name if that fails.

At this time we pull out from ip_fw2.c the logging functions, and
support for dynamic rules, and move kernel-only stuff into
netinet/ipfw/ip_fw_private.h
No ABI change involved in this commit, unless I made some mistake.
ip_fw.h has changed, though not in the userland-visible part.
Files touched by this commit:
conf/files
now references the two new source files
netinet/ip_fw.h
remove kernel-only definitions gone into netinet/ipfw/ip_fw_private.h.
netinet/ipfw/ip_fw_private.h
new file with kernel-specific ipfw definitions
netinet/ipfw/ip_fw_log.c
ipfw_log and related functions
netinet/ipfw/ip_fw_dynamic.c
code related to dynamic rules
netinet/ipfw/ip_fw2.c
removed the pieces that goes in the new files
netinet/ipfw/ip_fw_nat.c
minor rearrangement to remove LOOKUP_NAT from the
main headers. This require a new function pointer.
A bunch of other kernel files that included netinet/ip_fw.h now
require netinet/ipfw/ip_fw_private.h as well.
Not 100% sure i caught all of them.

accordingly.
With dst-ip or src-ip the option replicates two existing options.
When used with other arguments, the option can be useful to
quickly dispatch traffic based on other fields.

write to. This is specified in "options { directory }" in named.conf.
So, create /etc/namedb/working with appropriate permissions, and
update the entry in named.conf to match.
In addition to specifying the working directory, file and path names
in named.conf can be specified relative to the directory listed.
However, since that directory is now different from /etc/namedb
(where the configuration, zone, rndc.*, and other files are located)
further update named.conf to specify all file names with fully
qualified paths. Also update the comment about file and path names
so users know this should be done for all file/path names in the file.
This change will eliminate the 'working directory is not writable'
messages at boot time without sacrificing security. It will also
allow for features in newer versions of BIND (9.7+) to work as
designed.

seems to work like a tag that indicates 'not list end' of queued
frames. Without having a VGE_TXDESC_Q bit indicates 'list end'. So
the last frame of multiple queued frames has no VGE_TXDESC_Q bit.
The hardware has peculiar behavior for VGE_TXDESC_Q bit handling.
If the VGE_TXDESC_Q bit of descriptor was set the controller would
fetch next descriptor. However if next descriptor's OWN bit was
cleared but VGE_TXDESC_Q was set, it could confuse controller.
Clearing VGE_TXDESC_Q bit for transmitted frames ensure correct
behavior.
o Separate TX/RX buffer DMA tag from TX/RX descriptor ring DMA tag.
o Separate RX buffer DMA tag from common buffer DMA tag. RX DMA
tag has different restriction compared to TX DMA tag.
o Add 40bit DMA address support.
o Adjust TX/RX descriptor ring alignment to 64 bytes from 256
bytes as documented in datasheet.
o Added check to ensure TX/RX ring reside within a 4GB boundary.
Since TX/RX ring shares the same high address register they
should have the same high address.
o TX/RX side bus_dmamap_load_mbuf_sg(9) support.
o Add lock assertion to vge_setmulti().
o Add RX spare DMA map to recover from DMA map load failure.
o Add optimized RX buffer handler, vge_discard_rxbuf which is
activated when vge(4) sees bad frames.
o Don't blindly update VGE_RXDESC_RESIDUECNT register. Datasheet
says the register should be updated only when number of
available RX descriptors are multiple of 4.
o Use __NO_STRICT_ALIGNMENT instead of defining VGE_FIXUP_RX which
is only set for i386 architecture. Previously vge(4) also
performed expensive copy operation to align IP header on amd64.
This change should give RX performance boost on amd64
architecture.
o Don't reinitialize controller if driver is already running. This
should reduce number of link state flipping.
o Since vge(4) drops a driver lock before passing received frame
to upper layer, make sure vge(4) is still running after
re-acquiring driver lock.
o Add second argument count to vge_rxeof(). The argument will
limit number of packets could be processed in RX handler.
o Rearrange vge_rxeof() not to allocate RX buffer if received
frame was bad packet.
o Removed if_printf that prints DMA map failure. This type of
message shouldn't be used in fast path of driver.
o Reduce number of allowed TX buffer fragments to 6 from 7. A TX
descriptor allows 7 fragments of a frame. However the CMZ field
of descriptor has just 3bits and the controller wants to see
fragment + 1 in the field. So if we have 7 fragments the field
value would be 0 which seems to cause unexpected results under
certain conditions. This change should fix occasional TX hang
observed on vge(4).
o Simplify vge_stat_locked() and add number of available TX
descriptor check.
o vge(4) controllers lack padding short frames. Make sure to fill
zero for the padded bytes. This closes unintended information
disclosure.
o Don't set VGE_TDCTL_JUMBO flag. Datasheet is not clear whether
this bit should be set by driver or write-back status bit after
transmission. At least vendor's driver does not set this bit so
remove it. Without this bit vge(4) still can send jumbo frames.
o Don't start driver when vge(4) know there are not enough RX
buffers.
o Remove volatile keyword in RX descriptor structure. This should
be handled by bus_dma(9).
o Collapse two 16bits member of TX/RX descriptor into single 32bits
member.
o Reduce number of RX descriptors to 252 from 256. The
VGE_RXDESCNUM is 16bits register but only lower 8bits are valid.
So the maximum number of RX descriptors would be 255. However
the number of should be multiple of 4 as controller wants to
update 4 RX descriptors at a time. This limits the maximum
number of RX descriptor to be 252.
