51afc2c68c usb: cosmetic: double const
For plain array const can be either before or after
the type definition. Adding both is simply redundand.
Remove the later one.

9a04a858eb net: asix: don't pad odd-length TX packets
For Ethernet/USB RX packets, the ASIX HW pads odd-sized packets so that
they have an even size. Currently, asix_recv() does remove this padding,
and asic_send() adds equivalent padding in the TX path. However, the HW
does not appear to need this packing for TX packets in practical testing
with "ASIX Elec. Corp. AX88x72A 000001" Vendor: 0x0b95 Product 0x7720
Version 0.1. The Linux kernel does no such padding for the TX path.

Remove the padding from the TX path:

* For consistency with the Linux kernel.
* NVIDIA has a Tegra simulator which validates that the length of USB
  packets sent to an ASIX device matches the packet length value inside
  the packet data. Having U-Boot and the kernel do the same thing when
  creating the TX packets simplifies the simulator's validation.

4edcf0a3df usb: asix: Move software resets to basic_init
The ASIX driver calls a basic_init() function during get_info(), so that
not all initialization tasks need to be redone on every init().
Unfortunately, the most important one is still triggered too often: the
driver does a full port and MII reset on every asix_init(), requiring up
to several seconds to reestablish the link.

This patch confines that software reset into the asix_basic_init()
function so that it will only be executed once. This saves about a
second of boot time on systems using BOOTP.

Note: this patch was previously submitted many moons ago as:

   usb: usbeth: asix: Do a fast init if link already established

That patch seens to have been lost or forgotten, so this is a rebased
version. It is tested on snow with a Asix USB dongle (Cisco).

1dff9d0f54 net: asix: add AX88772B support
Add AX88772B ID together with two fixes needed to make this work.

1. The packet length check has to be adjusted, as all ASIX chips
only use 11 bits to indicate the length. AX88772B uses the other
bits to indicate unrelated things, which cause the check to fail.
This fix is based on a fix for the Linux kernel by Marek Vasut.
Linux upstream commit: bca0beb9363f8487ac902931a50eb00180a2d14a

2. AX88772B provides several bulk endpoints. Only the first
IN/OUT endpoints work in the default configuration. So stop
enumeration after we found them to avoid overwriting the
endpoint config with a non-working one.

02c8d8cc6e net: asix: add read_mac function
Initial device MAC should be read while getting info about the
device, so it's wrong to only read it in asix_init().

Add a dedicated function to read the initial MAC, which is also
able to handle devices that have their initial MAC stored in
EEPROM. Call this function inasix_eth_get_info().

58f8fab8a4 net: asix: add write_hwaddr function
All ASIX chipsets aside from AX88172 are able to set the MAC
address on the hardware level. Add a function to expose this
ability.

To differentiate between chip types we now carry flags as driver
private data. Also while touching the asix_dongles array
constify this.

5fae53d0f1 net: asix: split out basic reset function
The basic device reset ensures that the device is ready to
service commands and does not need to get redone before each
network operation.

Split out the basic reset from asix_init() and instead call it
from asix_eth_get_info(), so that it only gets called once.
