b3d44a6800 cxgbe(4): tidy up some of the interaction between the Upper Layer
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.

692ad7ca94 Big wpi(4) overhaul! Not by me!
This is a sync against iwn(4) and openbsd.

- Add power management support;
- Add background scanning support;
- Fix few LORs;
- Handle rfkill switch state changes properly;
- Fix recovering after firmware failure;
- Add more error checking;
- Cleanup & disable by default debug output;
- Update macroses names;
- Other various fixes;
- Add IBSS support:
  - don't set data_ntries field for management frames;
- Add AHDEMO support:
    - fix padding;
- Sync eeprom functions;
- Use CMD_RXON_ASSOC where possible;
- Enable HW CCMP encryption/decryption for pairwise keys;
- Fix filter flags for CMD_RXON.

Tested (by submitter) - iwn 3945 NIC.  I have one somewhere; I'll
validate this later on and revert it if it's a problem.

Thanks!

c869aa71f0 Use direct hardware access for internal requests for KCS and SMIC. In
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().

64de80195b Add a new device control utility for new-bus devices called devctl. This
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.

022abe003f Add comment about why checking for 0xff is OK. There's two bits in the
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.

The gpiobus is responsible to keep track of the used pins and serialize
the access to pins.

Some of these features are important to devices that do not descend
directly from gpiobus and as such cannot make use of its features (one
classic example is gpioc that is attached to the GPIO controller and could
not, until now, make use of the gpiobus locking).
