If the forcedeth driver receives too much work in an interrupt, it
assumes it has a broken hardware with stuck IRQ. It works around the
problem by disabling interrupts on the nic but makes a printk while
holding device spinlog - which isn't smart thing to do if you have
netconsole on the same nic.
This patch moves the printk's out of the spinlock protected area.
Without this patch the machine hangs hard. With this patch everything
still works even when there is significant increase on CPU usage while
using the nic.

http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the
bonding driver may produce bogus combinations of the checksum
flags and SG/TSO.
For example, if you bond devices with NETIF_F_HW_CSUM and
NETIF_F_IP_CSUM you'll end up with a bonding device that
has neither flag set. If both have TSO then this produces
an illegal combination.
The bridge device on the other hand has the correct code to
deal with this.
In fact, the same code can be used for both. So this patch
moves that logic into net/core/dev.c and uses it for both
bonding and bridging.
In the process I've made small adjustments such as only
setting GSO_ROBUST if at least one constituent device
supports it.

bnx2_suspend() would not save the PCI state and so the memory enable bit

During the transition to the ethtool_ops way of doing things, we supported
calling the device's ->do_ioctl method to allow unconverted drivers to

use the ethtool_ops way, and so we no longer need to support this.
The bonding driver is the biggest beneficiary of this; it no longer
needs to call ioctl() as a fallback if ethtool_ops aren't supported.

Address of auto variable is not a userland pointer. A good thing, too,
since if pppol2tp_tunnel_getsockopt() would _really_ get a userland pointer
as argument, it would be an instant roothole...

The Coverity checker noted that we've already dereferenced "dev" when we
check whether it's NULL.
Since it's impossible that "dev" is NULL at this place this patch
removes the NULL check.

phy_read() returns a negative number if there's an error, but the
error-checking code in the Vitesse driver's config_intr function
triggers if phy_read() returns non-zero. Correct that.

Change the threshold number of descriptors used to trigger CMB writes.
The vendor reports that under certain conditions this will reduce the
number of unnecessary tx interrupts and improve rx performance.
This change is lifted directly from vendor version 1.2.40.2 of the L1
driver.

Fixed rare issue that 'lv1_net_start_rx_dma failed, status=-9" was shown
in dmesg. This meant restarting rx DMA had been rejected by the hypervisor.
This issue would caused if the guest os requested starting DMA when
the hypervisor thought the DMA was in progress.
The state machine for DMA status of the hypervisor would be updated
by processing interrupt in the hypervisor.
Thus we should wait for the interrupt delivery before restarting
DMA.
