The WRB header is setup by wrb_fill_hdr() routine. This routine currently
gets some of the WRB params as args and figures out rest of the WRB params
by looking at various fields in skb (like gso, checksum, vlan-tag etc).
All these params could instead be retrieved from the skb into a structure
and passed to this routine. This separates wrb_fill_hdr() to only provide
chip-specific code to fill the WRB. This also makes it simple to support
chips with different WRB formats.

NAND-tree is used to check wiring between MAC and PHY using NAND gates
on the PHY side, hence the name.

NAND-tree initial status is latched at reset by probing the IRQ pin.
However some devices are sharing the PHY IRQ pin with other peripherals
such as Atmel SAMA5D[34]x-EK boards when using the optional TM7000
display module, therefore they are switching the PHY in NAND-tree test
mode depending on the current IRQ line status at reset.

This patch ensure PHY is not in NAND-tree test mode for all Micrel PHYs
using IRQ line as a NAND-tree toggle mode at reset.

There is a capability which let the hw could change the settings
automatically when the power change to ON. However, the USB reset
would reset the settings to the hw default, so the driver has to
restore the relative settings. Otherwise, it would influence the
functions of the hw, and the compatibility for the USB hub and
USB host controller.

The relative settings are as following.
 - set the power down scale to 96.
 - enable the power saving function of USB 2.0.
 - disable the ALDPS of ECM mode.
 - set burst mode depending on the burst size.
 - enable the flow control of endpoint full.
 - set fifo empty boundary to 32448 bytes.
 - enable the function of exiting LPM when Rx OK occurs.
 - set the connect timer to 1.

If skb allocation fails once the IP header has been received, the rx state is
being set to WAIT_SYNC. The logic, though, shouldn't directly return, as the
buffer may contain a full packet, and therefore the WAIT_SYNC state needs to be
processed (resetting state to WAIT_IP, clearing rx_buf_size and re-initializing
rx_buf_missing).

So, just let the while loop continue so that in the next iteration the WAIT_SYNC
state cleanly stops the loop. The WAIT_SYNC processing will be done just after
that, only if the end of packet is flagged.

Driver keeps adding multicast addresses without deleting removed MACs and
worrying about adapters filter limit. This results into actual count of programmed
multicast addresses get accumulated over the time and overruns the adapter's
filter limit without putting device in ACCEPT_ALL_MULTI mode. This causes
newly added multicast traffic to fail after the sequence of addition - deletion
in certain pattern.

This issue is seen only when netdev's mcast list count is less than adapters
mcast filter limit.

e.g. If adapters multicast filter limit is 38 per function
     then following sequence would result in multicast traffic failure for
     newly added MACs.
     - add less than 38 multicast MACs
     - remove previously added multicast MACs
     - add new multicast MACs (less than 38)

Remote checksum offload processing is currently the same for both
the GRO and non-GRO path. When the remote checksum offload option
is encountered, the checksum field referred to is modified in
the packet. So in the GRO case, the packet is modified in the
GRO path and then the operation is skipped when the packet goes
through the normal path based on skb->remcsum_offload. There is
a problem in that the packet may be modified in the GRO path, but
then forwarded off host still containing the remote checksum option.
A remote host will again perform RCO but now the checksum verification
will fail since GRO RCO already modified the checksum.

To fix this, we ensure that GRO restores a packet to it's original
state before returning. In this model, when GRO processes a remote
checksum option it still changes the checksum per the algorithm
but on return from lower layer processing the checksum is restored
to its original value.

In this patch we add define gro_remcsum structure which is passed
to skb_gro_remcsum_process to save offset and delta for the checksum
being changed. After lower layer processing, skb_gro_remcsum_cleanup
is called to restore the checksum before returning from GRO.
