This probably supports other devices based on SeaBIOS, which need
to be added to the smbios based quirks table.
The functionality has been ported from DragonFlyBSD and adapted
to FreeBSD's more general purpose environment.
Devices not covered by a quirk shouldn't be affected at all. Thanks
to jhb and kostikbel for reviewing the code.

1. handle errors from nm_config(), if any (none of the FreeBSD drivers
currently returns an error on this function, so this change
is a no-op at this time
2. use a full memory barrier on ioctls
interrupts are enabled and the NIC is awake (think: loading a module)
then there's a not-quite-zero window where we'll get an interrupt
for the device before the attach method is called to finish setting
up the hardware.
Since I grab locks in ath_intr() to check various things, the locks
need to be ready much earlier.
- Use IEEE80211_F_DATAPAD;
- (c->ic_flags & IEEE80211_CHAN_PASSIVE) -> IEEE80211_IS_CHAN_PASSIVE(c);
- Convert ackfailcnt to int (there is dereference to *(int *) in ieee80211_ratectl_tx_complete());
- Fix & move cleanup to the end in wpi_rx_done();
- Add missed lock in wpi_update_beacon();
- Try to fix powersave.

Drivers (ULDs) and the base if_cxgbe driver.
Track the per-adapter activation of ULDs in a new "active_ulds" field.
This was done pretty arbitrarily before this change -- via TOM_INIT_DONE
in adapter->flags for TOM, and the (1 << MAX_NPORTS) bit in
adapter->offload_map for iWARP.
iWARP and hw-accelerated iSCSI rely on the TOE (supported by the TOM
ULD). The rules are:
a) If the iWARP and/or iSCSI ULDs are available when TOE is enabled then
iWARP and/or iSCSI are enabled too.
b) When the iWARP and iSCSI modules are loaded they go looking for
adapters with TOE enabled and enable themselves on that adapter.
c) You cannot deactivate or unload the TOM module from underneath iWARP
or iSCSI. Any such attempt will fail with EBUSY.

particular, updates to the watchdog should no longer sleep.
- Add a new IPMI_IO_LOCK for low-level I/O access. Use this for
kcs_polled_request() and smic_polled_request().
- Add a new backend callback "ipmi_driver_request" to handle a driver
request. The new callback performs the request sychronously for KCS
and SMIC. SSIF still defers the work to the worker thread since the
worker thread sleeps during request processing anyway.
- Allocate driver requests on the stack rather than using malloc().

allows the user to request administrative changes to individual devices
such as attach or detaching drivers or disabling and re-enabling devices.
- Add a new /dev/devctl2 character device which uses ioctls for device
requests. The ioctls use a common 'struct devreq' which is somewhat
similar to 'struct ifreq'.
- The ioctls identify the device to operate on via a string. This
string can either by the device's name, or it can be a bus-specific
address. (For unattached devices, a bus address is the only way to
locate a device.) Bus drivers register an eventhandler to claim
unrecognized device names that the driver recognizes as a valid address.
Two buses currently support addresses: ACPI recognizes any device
in the ACPI namespace via its full path starting with "\" and
the PCI bus driver recognizes an address specification of
'pci[<domain>:]<bus>:<slot>:<func>' (identical to the PCI selector
strings supported by pciconf).
- To make it easier to cut and paste, change the PnP location string
in the PCI bus driver to output a full PCI selector string rather
than 'slot=<slot> function=<func>'.
- Add a devctl(3) interface in libdevctl which provides a wrapper around
the ioctls and is the preferred interface for other userland code.
- Add a devctl(8) program which is a simple wrapper around the requests
supported by devctl(3).
- Add a device_is_suspended() function to check DF_SUSPENDED.
- Add a resource_unset_value() function that can be used to remove a
hint from the kernel environment. This is used to clear a
hint.<driver>.<unit>.disabled hint when re-enabling a boot-time
disabled device.

ISR that are normally clear. RST is one, though in some overflow cases
it can be set. RDC is only set when a remote DMA is finished from the
memory mapped memory to the transmit rings, which we poll fore in the
code with ED_LOCK around the operation that would set it.
KVM clock shares the same data structures between the guest and the host
as Xen so it makes sense to just have a single copy of this code.
