c15895ef30 uwb: wrong sizeof argument in mac address compare
In the __uwb_beca_find_bymac function the sizeof returns
the length of a pointer and not the data it is referring
to. Hence only the first 4 bytes were compared, not the
entire 6 bytes MAC address. Now the sizeof takes struct
uwb_mac_addr as argument.

8092d7c978 uwb: don't use printk_ratelimit() so often
Avoid using printk_ratelimit() in many places because:
  - many were error messages reporting broken hardware (it's useful to
    get all of these).
  - the message itself wasn't useful so the message has been removed.

The UWB stack has some sysfs APIs that will change thus it's best
marked as EXPERIMENTAL until these APIs are finalized.

b63795fa3a uwb: dont tranmit identification IEs
The current identification IE doesn't include any useful information
(the vendor ID is from the EUI-48) and it causes problems with certain
hardware/firmware so don't transmit one.

b5784f10d5 uwb: i1480/GUWA100U: fix firmware download issues
IOGear firmware versions >= 1.4.12224 fail to be downloaded because of a
spurious (and harmless) RCEB received after the download notification. This
patch handles this RCEB and keeps compatibility with future versions that might
not emit this RCEB.

i1480_rceb_check() is reused to check for the RCEB. It is also refactored with
improved comments and reused in another place in mac.c where the checking was
being duplicated.

This patch was tested on both i1480 and GUWA100U HWAs, with all firmware
versions currently available.

8c7e8cb855 uwb: i1480: remove MAC/PHY information checking function
Some hardware/firmware combinations (most notably an IOGear HWA using the i1480
firmware) kill the host controller after issuing a GET_MAC_PHY_INFO command.
Removing this check seems harmless otherwise.

The patch fixes the issue where the HC is killed, showing the message:

ehci_hcd 0000:00:1d.7: HC died; cleaning up

After this error, USB comes back only after reloading the ehci_hcd module.

fa21183326 uwb: add Intel i1480 HWA to the UWB RC quirk table
The Intel i1480 HWA uses WHCI commands/events even though reporting itself as
WUSB compliant. This patch fixes this by marking it with the
WUSB_QUIRK_WHCI_CMD_EVT flag, which disables WUSB command/event filtering.

e477a4982f uwb: disable command/event filtering for D-Link DUB-1210
The D-Link DUB-1210 HWA uses commands and events from the WHCI specification,
although reporting itself as WUSB compliant. Therefore, we disable WUSB
command/event filtering for it.

USB_DEVICE_AND_INTERFACE_INFO is used for matching only the RC interface.
