Some devices do not support the 8 byte variants of the NTB input
size control messages despite announcing such support in their
NCM or MBIM functional descriptor.

According to the NCM specification, all devices must support the
4 byte variant regardless of whether or not the flag is set:

  If bit D5 is set in the bmNetworkCapabilities field of
  function’s NCM Functional Descriptor, the host may
  set wLength either to 4 or to 8. If wLength is 4, the
  function shall assume that wNtbInMaxDatagrams is to be
  set to zero. If wLength is 8, then the function shall
  use the provided value as the limit. The function shall
  return an error response (a STALL PID) if wLength is set
  to any other value.

We do not set wNtbInMaxDatagrams in any case, so we can just as
well unconditionally use the 4 byte variant without losing any
functionality.  This works around the known firmware bug, and
simplifies the code considerably.

Each nexthop is added like a single route in the routing table. All routes
that have the same metric/weight and destination but not the same gateway
are considering as ECMP routes. They are linked together, through a list called
rt6i_siblings.

ECMP routes can be added in one shot, with RTA_MULTIPATH attribute or one after
the other (in both case, the flag NLM_F_EXCL should not be set).

RFC 5961 5.2 [Blind Data Injection Attack].[Mitigation]

  All TCP stacks MAY implement the following mitigation.  TCP stacks
  that implement this mitigation MUST add an additional input check to
  any incoming segment.  The ACK value is considered acceptable only if
  it is in the range of ((SND.UNA - MAX.SND.WND) <= SEG.ACK <=
  SND.NXT).  All incoming segments whose ACK value doesn't satisfy the
  above condition MUST be discarded and an ACK sent back.

Move tcp_send_challenge_ack() before tcp_ack() to avoid a forward
declaration.

The SO_BINDTODEVICE option is the only SOL_SOCKET one that can be set, but
cannot be get via sockopt API. The only way we can find the device id a
socket is bound to is via sock-diag interface. But the diag works only on
hashed sockets, while the opt in question can be set for yet unhashed one.

That said, in order to know what device a socket is bound to (we do want
to know this in checkpoint-restore project) I propose to make this option
getsockopt-able and report the respective device index.

Another solution to the problem might be to teach the sock-diag reporting
info on unhashed sockets. Should I go this way instead?

====================
This patch series prepares the old at91_ether driver for code sharing
with the macb driver. The hardware is similar except for DMA TX/RX, so
its not quite clear if it is practical to support both in one
driver. But stuff like MDIO and statistics should be possible to
share.

Patch 1 adds some register defines and bits that is only found on
RM9200.

Patch 2-4 uses the register defines and access functions from the macb
header. These can be squashed if it cause too much churn.

Patch 5 merges the private at91_ether struct with the private macb
struct. This makes it easier to later share code with the macb. The
private macb struct becomes quite large, but most at91_ether specific
members are removed in later patches.

Patch 8 make macb compile when we select at91_ether. Is this approach
okey?

Patch 9 makes use of MDIO code from macb. This rips out the private
phy handling code in at91_ether. One thing that is lost is the
interrupt support for phy. But this should easy to add to macb which
will then benefit both drivers.

Patch 10 makes use of the macb_set_rx_mode from macb.

Patch 11-12 makes at91_ether share the rx dma struct members from
macb. Patch also moves the rx buffer allocation into netdev open and
dealloc into netdev close.

Last patch remove the now unused rm9200 emac header from include/mach.
