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.

This rips out the at91_ether phy handling and ethtool stuff

This change makes it so that igb_update_dca is broken into two halves, one

This change helps to address locking issues seen with
netif_set_real_num_tx_queues and netif_set_real_num_rx_queues when used in
the igb_set_interrupt_capability function. To resolve these locking issues
I have moved the two function calls into __igb_open so that they can be
called while the RTNL lock is held.
An added advantage to this is that the number of queues is not updated
until the last possible moment so if there are any issues in allocating
MSI-X interrupts or resources for the rings we have time to change the
values prior to updating the netdev.

This change makes it so that we no longer use header split. The idea is to
reduce partial cache line writes by hardware when handling frames larger
then header size. We can compensate for the extra overhead of having to
memcpy the header buffer by avoiding the cache misses seen by leaving an
full skb allocated and sitting on the ring.

This change makes it so that we can have limited support for jumbo frames
when SR-IOV is enabled. In order to accomplish this it is necessary to
disable all VFs when the PF has jumbo frames enabled. If the VFs then
request the same maximum frame size as the PF they will be re-enabled. A
follow on patch will add a means of identifying when a VF can support
spanning buffers and does not need to be worried about the actual supported
max frame size.
