larger than normal frames, to account for the case where a bge(4) NIC
is used with VLANs. Since we set the IFCAP_VLAN_MTU flag, we must allow
reception of frames up to 1522 bytes in size rather than 1518.
Note that it is possible to work around this bug by doing:
# ifconfig bge0 mtu 1504
prior to configuring any VLAN interfaces.
recompiling the driver. See the comments near the top of "if_em.h"
for descriptions of these delays. Four new loader tunables control
the system-wide default values:
hw.em.tx_int_delay
hw.em.rx_int_delay
hw.em.tx_abs_int_delay
hw.em.rx_abs_int_delay
The tunables are specified in microseconds. The valid range is
0-67108 usec., and 0 means that the timer is disabled.
There are also four new sysctls (actually, a set of four for each
"em" device in the system) to query and change the interrupt delays
after the system is up:
hw.em0.tx_int_delay
hw.em0.rx_int_delay
hw.em0.tx_abs_int_delay (not present for 82542/3/4 adapters)
hw.em0.rx_abs_int_delay (not present for 82542/3/4 adapters)
It seems to be OK to change these values even while the adapter is
passing traffic.

This is controlled by a per-adapter sysctl hw.atm.hfaX.shape. When
set to 0, no shaping occures. When set to 1 at most 1 channel is
shaped. When set to 2 all CBR channels are shaped. Note, that the
latter may actually not work, because of the adapter supporting
the shaping of only one PDU at the same time.
also do it). Three problems have been encountered:
1. The initialisation command does not work in interrupt mode. Whether
this is a firmware bug or a feature is not clear. The original Fore
drivers execute the initialize command always in polling mode, so
it appears that this behaviour is expected. When we detect a 4.X.Y
firmware do busy wait on the command status.
2. The command code of the GET_PROM command has changed. This is an
unofficial command anyway. What was GET_PROM in 3.X.Y is CLEAR_STATS
in 4.X.Y (although unimplemented in the firmware). We need to
use the correct code depending on the firmware.
3. The 4.X.Y firmware can set the error flag in the command status
without also setting the completion flag (as the documenation says).
Check both variants.
An additional field in the per-card structure fu_ft4 is TRUE when we have
detected a 4.X.Y firmware. Otherwise it is false. The behaviour of the
driver when using a 3.X.Y firmware should be identical to the previous
behaviour.
This change will enable traffic shaping of (at least one) CBR channels.

a more robust approach to indicate a device was probed via ECDT by setting
the private ivar to be &acpi_ec_devclass. Without the acpi_MatchHid() call
now, it might have been possible for a non-EC device to have had its magic

to EcGpeQueryHandler on to any waiting threads through the softc. Similar
behavior was in the original version.
Also:
* Merge EcQuery into EcGpeQueryHandler to simplify locking
* Hold EcLock from the initial read of the CSR down to the wakeup or
until after the query command has been processed.
* ec_gpebit only needs to be a UINT8
namespace has been evaluated. Machines with ACPI 2.0 expect this behavior
and have AML which calls EC functions early in the boot process. If the
ECDT is not available, fall back to original probe behavior.
Other minor changes:
* Add GPE bit and GLK usage to the device announcement
* Always use the global lock in the ECDT case, but potentially downgrade to
not using it if _GLK is 0 once the namespace is available. This is
announced with "Changing GLK from 1 to 0"
* Remove the acpi_object_list definitions which were earlier deprecated

- 5705 doesn't support jumbo frames
- Statistics must be read from registers
- RX return ring must be capped at 512 entries
- Omit initialization of certain device blocks
- Acknowledge link change interrupts by setting the 'link changed'
bit in the status register (used to have no effect)
- Remember to toggle the MI completion bit too
- Set the mbuf low watermark differently (on-chip memory buffers,
not BSD mbufs)
- Don't enable Ethernet@WireSpeed feature for certain 5705 chip revs
- Add additional PCI IDs for 5705 and 5782 parts
- Add a forgotten 5704 PCI ID
