On the DM9000B, dm9000_msleep() is called during the dm9000_timeout()
routine. Since dm9000_timeout() holds the main spinlock through the
entire routine, mdelay() needs to be used rather than msleep().
Furthermore, the mutex_lock()/mutex_unlock() should be avoided so as to
not sleep with spinlocks held.

DM9000 uses level-triggered interrupts. Some systems (PXA270) only
support edge-triggered interrupts on GPIOs. Some changes are necessary
to ensure that interrupts are not triggered while the GPIO interrupt is
masked or we will miss the interrupt forever.
* Make some helper functions called dm9000_mask_interrupts() and
dm9000_unmask_interrupts() for readability.
* dm9000_init_dm9000(): ensure that this function always leaves interrupts
masked regardless of the state when it entered the function. This is
primarily to support the situation in dm9000_open where the logic used
to go:
dm9000_open()
dm9000_init_dm9000()
unmask interrupts
request_irq()
If an interrupt occurred between unmasking the interrupt and
requesting the irq, it would be missed forever as the edge event would
never be seen by the GPIO hardware in the PXA270. This allows us to
change the logic to:
dm9000_open()
dm9000_init_dm9000()
dm9000_mask_interrupts()
request_irq()
dm9000_unmask_interrupts()
* dm9000_timeout(), dm9000_drv_resume(): Add the missing
dm9000_unmask_interrupts() now required by the change above.
* dm9000_shutdown(): Use mask helper function
* dm9000_interrupt(): Use mask/unmask helper functions

09ee9f8 were not incorporated into the dm9000_probe reset.

"At the moment you call register_netdev() the device is visible, notifications
are sent to userspace, and userland tools can try to bring the interface up
and see the incorrect link state, before you do the netif_carrier_off().
Said another way, between the register_netdev() and netif_carrier_off() call,
userspace can see the device in an inconsistent state."

i40evf_set_ringparam was broken in several ways. First, it only changed
the size of the first ring, and second, changing the ring size would
often result in a panic because it would change the count before
deallocating resources, causing the driver to either free nonexistent
buffers, or leak leftover buffers.
Fix this by storing the descriptor count in the adapter structure, and
updating the count for each ring each time we allocate them. This
ensures that we always free the right size ring, and always end up with
the requested count when the device is (re)opened.

Intel Wired LAN Driver Updates
This series contains updates to e1000, igb and ixgbe.
Emil provides his version 2 fix for the detection of SFP+ capable interfaces.
In cases where the driver is loaded while there are no SFP+ modules in cage,
the interface was not being detected as SFP capable. Resolve the issue by
identifying interfaces with no PHY type set as SFP capable which allows the
driver to detect the SFP module when the interface is brought up. In this
version 2 of the patch, the 82599 specific check was removed since we only
have 82598 devices that are SFP capable.
Jacob removes the including of the export header in the ixgbe PTP core, since
it is not needed. Renames igb_ptp_enable() to igb_ptp_feature_enable() to
better reflect the actual functions purpose.
Todd fixes the ethtool loopback test for i354 backplane devices since we
do not know what PHY is to be used for the devices, use MAC loopback for
ethtool tests. Todd also sets the packet buffer size register defaults for
i210 devices.
Yongjian Xu removes the check for skb->len being negative or zero since there
is never a case where it would be zero or negative for e1000.
Manuel Schölling updates e1000 to use the time_after() helper function.

In cases where the driver is loaded while there are no SFP+ modules in
the cage the interface was not being detected as SFP capable. To account
for this the driver called identify_sfp in ixgbe_get_settings to make
sure the data is correct. However when there is no SFP+ module in the cage
the driver waits for the I2C reads to time out which can take more than a
second and will cause issues with tools (like net-snmp) that may poll
for that information.
This patch resolves the issue by identifying interfaces with no PHY
type set as SFP capable which allows the driver to detect the SFP module
when the interface is brought up. As result of this we can also remove the
identify_sfp call from ixgbe_get_settings.
v2: remove the 82599 specific check since we have 82598 devices that are SFP
capable.

The current behaviour of the sh_eth driver is not to use the RNC bit
for the receive ring. This means that every packet recieved is not only
generating an IRQ but it also stops the receive ring DMA as well until
the driver re-enables it after unloading the packet.
This means that a number of the following errors are generated due to
the receive packet FIFO overflowing due to nowhere to put packets:
net eth0: Receive FIFO Overflow
Since feedback from Yoshihiro Shimoda shows that every supported LSI
for this driver should have the bit enabled it seems the best way is
to remove the RMCR default value from the per-system data and just
write it when initialising the RMCR value. This is discussed in
the message (http://www.spinics.net/lists/netdev/msg284912.html).
I have tested the RMCR_RNC configuration with NFS root filesystem and
the driver has not failed yet. There are further test reports from
Sergei Shtylov and others for both the R8A7790 and R8A7791.
There is also feedback fron Cao Minh Hiep[1] which reports the
same issue in (http://comments.gmane.org/gmane.linux.network/316285)
