refactors this code into be_vf_setup() and be_vf_clear(). The

Problem using big mtu around 4096 bytes is you end allocating (4096

8192 bytes : order-1 pages
It's better to limit the mtu to SKB_MAX_HEAD(NET_SKB_PAD),
to have no more than one page per skb.
Also the patch changes the netdev_alloc_skb_ip_align() done in
init_dma_desc_rings() and uses a variant allowing GFP_KERNEL allocations
allowing the driver to load even in case of memory pressure.

This patch enhances the STMMAC driver to support CHAINED mode of
descriptor.
STMMAC supports DMA descriptor to operate both in dual buffer(RING)
and linked-list(CHAINED) mode. In RING mode (default) each descriptor
points to two data buffer pointers whereas in CHAINED mode they point
to only one data buffer pointer.
In CHAINED mode each descriptor will have pointer to next descriptor in
the list, hence creating the explicit chaining in the descriptor itself,
whereas such explicit chaining is not possible in RING mode.
First version of this work has been done by Rayagond.
Then the patch has been reworked avoiding ifdef inside the C code.
A new header file has been added to define all the functions needed for
managing enhanced and normal descriptors.
In fact, these have to be specialized according to the ring/chain usage.
Two new C files have been also added to implement the helper routines
needed to manage: jumbo frames, chain and ring setup (i.e. desc3).

The ehea adapter has a mode where it will avoid partial cacheline DMA
writes on receive by always padding packets to fall on a cacheline
boundary.
Unfortunately we currently aren't allocating enough space for a full
ethernet MTU packet to be rounded up, so this optimisation doesn't hit.
It's unfortunate that the next largest packet size exposed by the
hypervisor interface is 2kB, meaning our skb allocation comes out of a
4kB SLAB. However the performance increase due to this optimisation is
quite large and my TCP stream numbers increase from 900MB to 1000MB/sec.

- Use skb_record_rx_queue to record which queue an skb came in on.
- Remove the driver specific netif_queue lock and use the networking
stack transmit lock instead.
- Remove the driver specific transmit queue hashing and use
skb_get_queue_mapping instead.
- Use netif_tx_{start|stop|wake}_queue where appropriate. We can also
remove pr->queue_stopped and just check the queue status directly.
- Print all 16 queues in the ethtool stats.

Commit 67fd4fcb (e1000e: convert to stats64) added the ability to update
statistics more accurately and on-demand through the net_device_ops
.ndo_get_stats64 hook, but introduced a locking bug on 82577/8/9 when
linked at half-duplex (seen on kernels with CONFIG_DEBUG_ATOMIC_SLEEP=y and
CONFIG_PROVE_LOCKING=y). The commit introduced code paths that caused a
mutex to be locked in atomic contexts, e.g. an rcu_read_lock is held when
irqbalance reads the stats from /sys/class/net/ethX/statistics causing the
mutex to be locked to read the Phy half-duplex statistics registers.
The mutex was originally introduced to prevent concurrent accesses of
resources (the NVM and Phy) shared by the driver, firmware and hardware
a few years back when there was an issue with the NVM getting corrupted.
It was later split into two mutexes - one for the NVM and one for the Phy
when it was determined the NVM, unlike the Phy, should not be protected by
the software/firmware/hardware semaphore (arbitration of which is done in
part with the SWFLAG bit in the EXTCNF_CTRL register). This latter
semaphore should be sufficient to prevent resource contention of the Phy in
the driver (i.e. the mutex for Phy accesses is not needed), but to be sure
the mutex is replaced with an atomic bit flag which will warn if any
contention is possible.
Also add additional debug output to help determine when the sw/fw/hw
semaphore is owned by the firmware or hardware.

On i350 when traffic is looped back from a VF to the PF the value is byte
swapped from the normal format. In order to address this we need to add a
flag indicating that the ring will need to byte swap the loopback packets

Correct a check for change in FCoE priority when IEEE mode DCB is in use.
In IEEE mode a different function has to be used to get the FCoE priority

In case there should be more than one, check just the bit.

In order to be able to improve the performance of the TX path it has been
necessary to add addition info to the tx_buffer_info structure. However a
side effect is that the structure has gotten larger and this in turn has
also increased the size of the RX buffer info structure. In order to avoid
this in the future I am splitting the single buffer_info structure into two
separate ones and instead I will join them by making the buffer_info

There is a problem in the ixgbe driver with the reporting of the flow
control parameters. The autoneg parameter is shown to be of if
*either* it really is off, or current modes for both tx and rx are off.
The problem is seen when the parameters are read or set when the link
is down. In this case, the driver sees that tx and rx are currently off
and therefore autoneg parameter is incorrectly reported to be off too.
Also, the ethtool binary can not set the autoneg off since it sees that
it already is. When a link later comes up, the autonegotiation is
carried out normally and the driver later on reports the autoneg
parameter to be on (as it is) and then it can also be changed with
ethtool.
The patch is made against v3.0 kernel, but the problem seems to be there
since v2.6.30-rc1.
Reviewer comments: What we are trying to do is to disable flow control
while the cable is disconnected. Since ixgbe defaults to full flow
control, we call ethtool -A autoneg off rx off tx off while the cable
is disconnected. This doesn't work, because the driver sets
hw->fc.current_mode = ixgbe_fc_none if the cable is unplugged.
ixgbe_get_pauseparam() then reports to ethtool that nothing needs to be
done. The code fixes this, but it might have some unknown consequences.

Clear the data field in ixgbe_read_i2c_byte_generic so it does not
accumulate 1 bit using the same variable multiple times.

It some situations the driver sets __IXGBE_RESETTING and then
__IXGBE_DOWN flags. It is possible a link check may sneak in
between.
This patch adds check for both flags.
The idea is to reduce register reads while the PHY is resetting.

drivers/net/built-in.o: In function `bfa_ioc_ct2_poweron':
(.text+0xcdc90): multiple definition of `bfa_ioc_ct2_poweron'
drivers/scsi/built-in.o:(.text+0x17f9a0): first defined here
This patch renames bfa_ioc_ct2_poweron() to bfa_nw_ioc_ct2_poweron() to avoid
multiple definition with Brocade scsi driver. It also modifies asic specific
interface setup to allocate MSIX resources at power on in case of 1860 HW with
no asic block and warns if the asic gen is neither BFI_ASIC_GEN_CT nor
BFI_ASIC_GEN_CT2.
