This is important patch for new devices that support unaligned
addressing. That devices suffer from the backward-compatibility bug in
DMA engine. In theory we should be able to use old mechanism, but in
practice DMA address seems to be randomly copied into status register
when hardware reaches end of a ring. This breaks reading slot number
from status register and we can't use DMA anymore.

Some devices (BCM4749, BCM5357, BCM53572) have internal switch that
requires initialization. We already have code for this, but because
of the typo in code it was never working. This resulted in network not
working for some routers and possibility of soft-bricking them.

Use correct bit for switch initialization and fix typo in the define.

running bonding in ALB mode requires that learning packets be sent periodically,
so that the switch knows where to send responding traffic.  However, depending
on switch configuration, there may not be any need to send traffic at the
default rate of 3 packets per second, which represents little more than wasted
data.  Allow the ALB learning packet interval to be made configurable via sysfs

The NULL deref happens when br_handle_frame is called between these
2 lines of del_nbp:
	dev->priv_flags &= ~IFF_BRIDGE_PORT;
	/* --> br_handle_frame is called at this time */
	netdev_rx_handler_unregister(dev);

In br_handle_frame the return of br_port_get_rcu(dev) is dereferenced
without check but br_port_get_rcu(dev) returns NULL if:
	!(dev->priv_flags & IFF_BRIDGE_PORT)

Eric Dumazet pointed out the testing of IFF_BRIDGE_PORT is not necessary
here since we're in rcu_read_lock and we have synchronize_net() in
netdev_rx_handler_unregister. So remove the testing of IFF_BRIDGE_PORT

Intel Wired LAN Driver Updates

This series contains updates to ixgbe and e1000e.

Jacob provides a ixgbe patch to fix the configure_rx patch to properly
disable RSC hardware logic when a user disables it.  Previously we only
disabled RSC in the queue settings, but this does not fully disable
hardware RSC logic which can lead to unexpected performance issues.

Emil provides three fixes for ixgbe.  First fixes the ethtool loopback
test when DCB is enabled, where the frames may be modified on Tx
(by adding VLAN tag) which will fail the check on receive.  Then a fix
for QSFP+ modules, limit the speed setting to advertise only one speed
at a time since the QSFP+ modules do not support auto negotiation.
Lastly, resolve an issue where the driver will display incorrect info
for QSFP+ modules that were inserted after the driver has been loaded.

David Ertman provides to fixes for e1000e, one removes a comparison to
the boolean value true where evaluating the lvalue will produce the
same result.  The other fixes an error in the calculation of the
rar_entry_count, which causes a write of unkown/undefined register
space in the MAC to unknown/undefined register space in the PHY.

When copying the MAC RAR registers to PHY there is an error in the
calculation of the rar_entry_count, which causes a write of unknown/
undefined register space in the MAC to unknown/undefined register space in
the PHY.

This patch fixes the overrun with writing to the PHY RAR and also fixes the
ethtool offline register tests so that the correctly addressed registers
have the appropriate bitmasks for R/W and RO bits for affected parts.

Shawn Rader gets credit for finding and fixing the register overrun.

QSFP+ modules do not support auto negotiation and should advertise only
one speed at a time.

This patch adds logic in ethtool to allow setting and reporting the
advertised speed at either 1Gbps or 10Gbps, but not both. Also limits
the speed set in ixgbe_sfp_link_config_subtask() to highest supported.
Previously the link was set to whatever the supported speeds were.
