just em, there is an igb driver (this follows behavior with our Linux drivers).
All adapters up to the 82575 are supported in em, and new client/desktop support
will continue to be in that adapter.
The igb driver is for new server NICs like the 82575 and its followons.
Advanced features for virtualization and performance will be in this driver.
Also, both drivers now have shared code that is up to the latest we have
released. Some stylistic changes as well.
Enjoy :)

Update and tidy the copyright.
Add "show sysregs" command to ddb. On i386, this gives gdt, idt, ldt,
cr0-4, etc. Support should be added for other platforms that have a
different set of registers for system use.
while still restricting auto-channel select to only those channels
permitted by regulatory constraints (sorta, we're still missing the
checks to honor radar and noadhoc status on channels). This somehow
got lost in the initial merge of the revised scanning code.

(e.g. 88E8053) but it's not identified which hardwares are affected.
Revision 1.4 of if_mskreg.h was not enough to workaround the bug.
To workaround it, inrease GMAC FIFO threshold by one FIFO word to
flush received pause frames.

only because there's a partition table where the boot sector has
boot code. Boot sectors without boot code look like a MBR for all
practical purposes. This change adds a check for the partition table
and fails the probe when it's obvously invalid. The assumption being
that the sector contains a boot sector and not a MBR.
More checks are needed to distinguish a boot secto without boot code
from a (empty) MBR.
This fixes the panic which happens when mdcreate_vnode() calls vn_close()
and mddestroy() calls it again further down the error handling path.

- Consolidate the code to humanize the size of a disk partition into a
single function based on the code for GPT partitions and use it for
GPT partitions, BSD slices, and BSD partitions.
- Teach the humanize code to use KB for small partitions (e.g. GPT boot
partitions now show up as 64KB rather than 0MB).
- Pad a few partition type names out so that things line up in the
common case.

e_rem_pio2.c:
This case goes up to about 2**20pi/2, but the comment about it said that
it goes up to about 2**19pi/2.
It went too far above 2**pi/2, giving a multiplier fn with 21 significant
bits in some cases. This would be harmful except for a numerical
accident. It happens that the terms of the approximation to pi/2,
when rounded to 33 bits so that multiplications by 20-bit fn's are
exact, happen to be rounded to 32 bits so multiplications by 21-bit
fn's are exact too, so the bug only complicates the error analysis (we
might lose a bit of accuracy but have bits to spare).
e_rem_pio2f.c:
The bogus comment in e_rem_pio2.c was copied and the code was changed
to be bug-for-bug compatible with it, except the limit was made 90
ulps smaller than necessary. The approximation to pi/2 was not
modified except for discarding some of it.
The same rough error analysis that justifies the limit of 2**20pi/2
for double precision only justifies a limit of 2**18pi/2 for float
precision. We depended on exhaustive testing to check the magic numbers
for float precision. More exaustive testing shows that we can go up
to 2**28pi/2 using a 53+25 bit approximation to pi/2 for float precision,
with a the maximum error for cosf() and sinf() unchanged at 0.5009
ulps despite the maximum error in rem_pio2f being ~0.25 ulps. Implement
this.
This reduces the size of a statically-linked binary by approximately 100KB
in a trivial "return (0)" test application. readelf -S was used to verify
that the .text section was reduced and that using strlen() saved a few
more bytes over using sizeof(). Since the section of code is only called
when environ is corrupt (program bug), I went with fewer bytes over fewer
cycles.
I made minor edits to the submitted patch to make the output resemble
warnx().

them. Thus, any fd whose value is greater than SHRT_MAX is handled
incorrectly (the short value is sign-extended when converted to an int).
An unpleasant side effect is that if fopen() opens a file and gets a
backing fd that is greater than SHRT_MAX, fclose() will fail and the file
descriptor will be leaked. Better handle this by fixing fopen(), fdopen(),
and freopen() to fail attempts to use a fd greater than SHRT_MAX with
EMFILE.
At some point in the future we should look at expanding the file descriptor
in FILE to an int, but that is a bit complicated due to ABI issues.

Make both these limits a sysctl, so it is easy to change the limit.
If the userland part of ipfw finds that the sysctls don't exist,
it will just fall back to the traditional limits.
(100 packets is quite a small limit these days. If you want to test
TCP at 100Mbps, 100 packets can only accommodate a DBP of 12ms.)
Note these sysctls in the man page and warn against increasing them
without thinking first.

device supports retrieving a serial number. Instead, first query the
list of VPD pages it does support, and only query the serial number if
it's supported, else silently move on. This eliminates a lot of noise
during verbose booting, and will likely eliminate the need for most
NOSERIAL quirks.
{SHRT_MAX}, so {STREAM_MAX} should be no greater than that. (This
does not exactly meet the letter of POSIX but comes reasonably close
to it in spirit.)
