The 5717 sets up TSO slightly differently in the transmit path. It
looks like this method will be the new way of doing things. This patch
defines a flag to indicate this.

This patch consolidates the TSO capability discovery code into its own
code block. The code that decides whether or not to allow TSO is then
cleaned up. Finally, the patch consolidates all MSI and MSIX
capability code into a single code block.

We need room for another TSO flag and it would be most efficient if it
resided in tg3_flags2. This patch moves the TG3_FLG2_PROTECTED_NVRAM
to tg3_flags3 to make room.

This patch avoids reprogramming the RCB NIC addresses for all 5755 and

correct by default for all other affected devices.

The cu3088-driver used as common base for lcs- and ctcm-devices
makes it difficult to assign the appropriate driver to an lcs-device
or a ctcm-device. This patch eliminates the cu3088-driver and thus
the root device "cu3088". Path /sys/devices/cu3088 is replaced with
the pathes /sys/devices/lcs and /sys/devices/ctcm.
Patch is based on a proposal from Cornelia Huck.

This patch pairs similar-numbered Rx and Tx queues onto a single
MSI-X vector. For example, Tx queue 0 and Rx queue 0's interrupt
with be ethX-RxTx-0. This allows for more efficient cleanup, since
fewer interrupts will be firing during device operation. It also
helps with a cleaner CPU affinity for IRQ affinity.

We were previously only checking the first tx ring to see if it had any

of the rings so this patch makes it so that all of the rings are now being

This patch does some refactoring work that I felt was needed after reviewing
the changes recently submitted relating to the replacement of net_stats with
netdev->stats.
This patch essentially creates two different collections of stats. The
first handles the adapter specific states and is stored in gstring_stats,
and the second is for netdev specific stats and is stored in
gstring_net_stats.

This patch makes it so that nics such as 82576 and newer can support more
hardware queues when there are more than 4 cpus by combining a tx/rx queue
pair onto one interrupt so that 8 queue pairs can be supported and thus
allow for more queues.

Both vlan and macvlan devices usually don't use a qdisc and immediately
queue packets to the underlying device. Propagate transmission state of
the underlying device to the upper layers so they can react on congestion
and/or inform the sending process.

Add support for Wake on LAN (WOL) reception and waking the device up from
this signal via the ethtool interface. Currently we are only supporting
the magic-packet variant of wakeup.
WOL is enabled by specifying a second interrupt resource to the driver
which indicates where the interrupt for the WOL is being signalled. This
then enables the necessary ethtool calls to leave the device in a state
to receive WOL frames when going into suspend.

Before calling gfar_clean_tx_ring() the driver grabs an irqsave
spinlock, and then tries to recycle skbs. But since
skb_recycle_check() returns 0 with IRQs disabled, we'll never
recycle any skbs.
It appears that gfar_clean_tx_ring() and gfar_start_xmit() are
mostly idependent and can work in parallel, except when they
modify num_txbdfree.
So we can drop the lock from most sections and thus fix the skb
recycling.

gfar_error() can arrive at the middle of gfar_start_xmit() processing,
and so it can trigger transfers of BDs that we don't yet expect to
be transmitted.
