Repost patch of driver for LAN7800 family of USB 2.0 & USB 3.0 to Gigabit Ethernet.
- remove module param which can be configurable by standard mechanism.
- remove other module parms except msg_level per review comment.
- update to handle byte swap for statistics structure correctly.

btusb currently has a generic match on USB device descriptors:
        { USB_DEVICE_INFO(0xe0, 0x01, 0x01) },

However, http://www.usb.org/developers/defined_class states:

  Base Class E0h (Wireless Controller)
  This base class is defined for devices that are Wireless controllers.
  Values not shown in the table below are reserved. These class codes are
  to be used in Interface Descriptors, with the exception of the Bluetooth
  class code which can also be used in a Device Descriptor.

Add a match on the interface descriptors accordingly.

This fixes compatibility with the RTL8723AU device shown below.
This device conforms to the USB Interface Association Descriptor
specification, which requires the device to have class ef/02/01.
The extra IAD descriptor then specifies that interfaces 0 and 1
belong to the same function/driver, which is true. Provided that
the Bluetooth device class spec accepts use of the IAD, I imagine that
technically, all btusb devices should be configured like this.

Ethernet Management Datagrams (EMADs) are Ethernet packets sent between
the host and the device in order to configure the available device registers.
Another use case is notifications sent from the device to the host,
letting it know about certain events, such as port up / down.

Add the ability to construct EMADs with provisions to construct and
parse the registers' payloads. Implement EMAD transaction layer
which is responsible for the reliable transmission of EMADs. Also, add
an infrastructure used by the switch driver to register for particular
events generated by the device.

Current driver always uses vlan-promisc mode, i.e., it receives both
tagged and untagged traffic and lets the network stack drop packets
tagged with unrequested vlan tags.

This patch implements vlan-filtering offload in the driver -
Unless explicitly configured to promisc mode, only untagged packets or
packets tagged with requested vlans would reach the Rx flow.

It was used to update netdev priv parameters that require stopping
and re-opening the device in a generic way - it got the new
parameters and did: ndo_stop(), copy new parameters into current
parameters, ndo_open().

We chose to remove it for two reasons:
1) It requires additional instance of struct mlx5e_params on the
   stack and looking forward we expect this struct to grow.
2) Sometimes we want to do additional operations (besides
   just updating the priv parameters) while the netdev is stopped.
   For example, updating netdev->mtu @mlx5e_change_mtu() should
   be done while the netdev is stopped (done in this commit).

As part of defconfig consolidation using fragments, we'd like to be
able to have the same drivers enabled on 32-bit and 64-bit.  Gianfar
happens to only exist on 32-bit systems, and when building the
resulting 64-bit kernel warnings were produced.

A couple of the warnings are trivial, but the rfbptr code has deeper
issues.  It uses the virtual address as the DMA address, which again,
happens to work in the environments where this driver is currently
used, but is not the right thing to do.
