- Simplify MSI allocation to what is actually needed for a single one.
- Release the MSI and the corresponding bus resource as appropriate when
either the interrupt resource cannot be allocated or setting up the
interrupt fails.
- Error out when interrupt allocation or setup fails and polling is
disabled.
- Release the MSI after the corresponding bus resource so the former is
not leaked on detach.
- Remove a redundant softc member.

re-using a hardware propritary transfer descriptor, PTD, in USB host
mode. If the PTD's are recycled too quickly, it has been observed that
the hardware simply fails to schedule the requested job or resets
completely disconnecting all devices.
SAF1761 OTG driver. Currently the driver logic is very simple and
double buffering the USB transactions is not done. Also you need to
use an external USB high speed USB HUB for reliable FULL speed
outgoing ISOCHRONOUS traffic, because the internal one chokes on
so-called split transfers above 188 bytes.
search (i.e. without returning any result) and you would end up with a
random MAC address.
Change the search algorithm to a recursive one to ensure that all the nodes
on DTS will be verified.
The previous algorithm could not keep up if the DTS has too many sub-nodes.
While here, fix the punctuation on comments.

E5372 with different product IDs.
Interestingly, the standard E5372 IDs (12d1:1506) are currently listed in
u3g.c and are the same as the E3131. However, the R215/E5372 is an NCM
device and works well with cdce(4) whereas the E3131 isn't. More work
may be needed to better identify the other device IDs.

ports. The current bitmap array was too small to hold more than 16
bits and would at some point toggle the context size, which then would
trigger an enumeration fault and cause a fallback to the EHCI
companion controller, if any.

Huawei. It might appear as if the firmware is allocating memory blocks
according to the USB transfer size and if there is initially a lot of
data, like at the answering machine prompt, it simply dies without any
apparent reason. The simple workaround for this is to force a zero
length packet at hardware level after every 512 bytes of data. This
will force the other side to use smaller memory blocks aswell.
