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.

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.

The Intel i1480 HWA uses WHCI commands/events even though reporting itself as

The D-Link DUB-1210 HWA uses commands and events from the WHCI specification,
although reporting itself as WUSB compliant. Therefore, we disable WUSB

USB_DEVICE_AND_INTERFACE_INFO is used for matching only the RC interface.

The UWB stack used bitmaps to manage Medium Access Slot availability,

this patch turns the netdev timeout WARN_ON_ONCE() into a WARN_ONCE(),
so that the device and driver names are inside the warning message.
This helps automated tools like kerneloops.org to collect the data
and do statistics, as well as making it more likely that humans
cut-n-paste the important message as part of a bugreport.

with what I believe is a better fix than the one referenced
in the regression entry above.
These PNP header interfaces try to work in such a way that
you can reference some of them even if PNP is not enabled,
and the compiler was expected to optimize everything away.
Which is mostly fine, except that there was one interface
for which there was not provided an inline "NOP" implementation.
Once we add that, all of these compile failures cannot handle
any more.

The SEC's h/w IV out implementation DMAs the trailing encrypted payload
block of the last encryption to ctx->iv. Since the last encryption may
still be pending completion, we can sufficiently prevent successive
packets from being transmitted with the same IV by xoring with sequence
number.
Also initialize alg_list earlier to prevent oopsing on a failed probe.
