tables. Some drivers needed some slight re-arrangement of declarations
to accommodate this. Change the USB pnp tables slightly to allow
better compatibility with the system by moving linux driver info from
start of each entry to the end. All other PNP tables in the system
have the per-device flags and such at the end of the elements rather
that at the beginning.

from 1500 to 1496 bytes. The MTU should remain at 1500, extending the
frame size as per IEEE 802.3. Adding IFCAP_VLAN_MTU to the
if_capabilities field in the smsc driver solves the problem. The
datasheet for the LAN9512 chip, section 3.2.3 states that the chip
supports the extended frame.

IPv4/IPv6 checksum offloading and VLAN tag insertion/stripping.
Since uether doesn't provide a way to announce driver specific offload
capabilities to upper stack, checksum offloading support needs more work
and will be done in the future.
Special thanks to Hayes Wang from RealTek who gave input.
The mbuf length fields must be set before m_adj() is called else
m_adj() will not always adjust the mbuf and an unaligned read
exception can trigger inside the network stack. This can happen on
platforms where unaligned reads are not supported. Adjust a length
check to include the 2-byte ethernet alignment while at it.

variant of Microsoft RNDIS, i. e. their unofficial version of CDC ACM,
has been disabled in r261544 for resolving a conflict with umodem(4).
Eventually, in r275790 that problem was dealt with in the right way.
However, r275790 failed to put probing of RNDIS devices in question
back.
- Initialize the device prior to querying it, as required by the RNDIS
specification. Otherwise already determining the MAC address may fail
rightfully.
- On detach, halt the device again.
- Use UCDC_SEND_ENCAPSULATED_{COMMAND,RESPONSE}. While these macros are
resolving to the same values as UR_{CLEAR_FEATURE,GET_STATUS}, the
former set is way more appropriate in this context.
- Report unknown - rather: unimplemented - events unconditionally and
not just in debug mode. This ensures that we'll get some hint of what
is going wrong instead of the driver silently failing.
- Deal with the Microsoft ActiveSync requirement of using an input buffer
the size of the expected reply or larger - except for variably sized
replies - when querying a device.
- Fix some pointless NULL checks, style bugs etc.
This changes allow urndis(4) to communicate with a Microsoft-certified
USB RNDIS test token.

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.

interface. Make MII drivers forget about 'struct ifnet'.
Later plan is to provide an administrative downcall from ifnet
layer into drivers, to inform them about administrative status
change. If someone thinks that processing MII events for an
administratively down interface is a big problem, then drivers
would turn MII processing off.
The following MII drivers do evil things, like strcmp() on
driver name, so they still need knowledge of ifnet and thus
include if_var.h. They all need to be fixed:
sys/dev/mii/brgphy.c
sys/dev/mii/e1000phy.c
sys/dev/mii/ip1000phy.c
sys/dev/mii/jmphy.c

the defined length for AX88772B is different with other ASIX

not prepend a checksum header so driver has to use normal header
