to explicitly be 32 bits, as I can't really imagine a DMA device that
needs anything close to 2GB alignment of data.

The code is turned off until the tree is fixed up so it compiles.
__FreeBSD_version was already bumped once today, so skip the bump, but
add an entry to UPDATING.
Note that __DESCR() is used in the SYSCTL_OID() macro and so is not
needed in macros that invoke it. This use was inconsistent in the
file and I have made it consistent any lines already being changed.

dialog is distributed from GPLv2 to LGPLv2 and introduces a number of new
features and a new and better libdialog API. The existing libdialog will
be kept temporarily as libodialog for compatibility purposes until sade,
sysinstall and tzsetup have been either updated or replaced.
__FreeBSD_version is now 900030.

Some bits of the interrupt mask are part of the status register which is
saved with the process context, and these bits are initialized from the
cpu on which the process is created. This means that all the processes
should have the same value for these interrupt mask bits, so that the
interrupt mask remains the same regardless of what thread is scheduled
on the cpu.

limit maximum RX buffer size to RE_RX_DESC_BUFLEN instead of
blindly configuring it to 16KB. Due to lack of documentation, re(4)
didn't allow jumbo frame on these controllers. However it seems
controller is confused with jumbo frame such that it can DMA the
received frame to wrong address instead of splitting it into
multiple RX buffers. Of course, this caused panic.
Since re(4) does not support jumbo frames on these controllers,
make controller drop frame that is longer than RE_RX_DESC_BUFLEN
sized frame. Fortunately RTL810x controllers, which do not support
jumbo frame, have no such issues but this change also limited
maximum RX buffer size allowed to RTL810x controllers. Allowing
16KB RX buffer for controllers that have no such capability is
meaningless.

the pwm values. We can now set the fan's speed of a PWM controlled fan
with % numbers between 30 and 100 % instead of trying to model a
% number based on rpm.
The fcu chip offers both, the dutycycle and the rpm value of the PWM
controlled fans. I added the rpm value to the list of information
available via sysctl(8).

and just show old (cached) values. Controller will not respond to
the command unless MAC is enabled so DUMP request for down
interface caused request timeout.
RealTek changed TX descriptor format for later controllers so these
controllers require MSS configuration in different location of TX
descriptor. TSO is enabled by default for controllers that use new
descriptor format.
For old controllers, TSO is still disabled by default due to broken
frames under certain conditions but users can enable it.

These controllers consist of two Marvell 88SE9128 6Gbps SATA chips and
PLX PCIe bridge. As result, they seem to be agree to work with ahci(4)
as usual HBAs. The only noticed issue is that RAID BIOS disables all
drive caches during boot, though `camcontrol cmd ...` is able to fix that.
Those who wants RAID functionality can still use closed proprietary driver
from HighPoint site.

erroneously, assumed that 4 bytes of data were in the first
mbuf of a list by replacing the bcopy() with m_copydata().
Also, replace the uses of m_pullup(), which can fail for
reasons other than not enough data, with m_copydata().
For the cases where it isn't known that there is enough
data in the mbuf list, check first via m_len and m_length().
This is believed to fix a problem reported by dpd at dpdtech.com
and george+freebsd at m5p.com.

DMA boundary bug and runs with PCI-X mode. watchdog timeout was
observed on BCM5704 which lives behind certain PCI-X bridge(e.g.
AMD 8131 PCI-X bridge). It's still not clear whether the root
cause came from that PCI-X bridge or not. The watchdog timeout
indicates the issue is in TX path. If the bridge reorders TX
mailbox write accesses it would generate all kinds of problems but
I'm not sure. This should be revisited.

the DMA address space restriction was applied to all bge(4)
controllers such that it caused unnecessary performance degradation
for controllers that have no such issues.
