Secondary unicast and multicast addresses are added to the Receive
Address registers (RAR) for most parts supported by the driver. For
82579, there is only one actual RAR and a number of Shared Receive Address
registers (SHRAR) that are shared among the driver and f/w which can be
reserved and write-protected by the f/w. On this device, use the SHRARs
that are not taken by f/w for the additional addresses.
Add a MAC ops function pointer infrastructure (similar to other MAC
operations in the driver) for setting RARs, introduce a new rar_set
function for 82579 and convert the existing code that sets RARs on other
devices to a generic rar_set function.

An update to the EEPROM on 82579 will extend a delay in hardware to fix an
issue with WoL not working after a G3->S5 transition which is unrelated to
the driver. However, this extended delay conflicts with nominal operation
of the device when it is initialized by the driver and after every reset
of the hardware (i.e. the driver starts configuring the device before the
hardware is done with it's own configuration work). The workaround for
when the driver is in control of the device is to tell the hardware after
every reset the configuration delay should be the original shorter one.
Some pre-existing variables are renamed generically to be re-used with
new register accesses.

This patch (as1547) rearranges the Power Management parts of the
ehci-tegra driver to match the conventions used in other EHCI platform
drivers. In particular, the controller should not be powered down by
the root hub's suspend routine; the controller's power level should be
managed by the controller's own PM methods.
The end result of the patch is that the standard ehci_bus_suspend()
and ehci_bus_resume() methods can be used instead of special-purpose
routines. The driver now uses the standard dev_pm_ops methods instead
of legacy power management. Since there is no supported wakeup
mechanism for the controller, runtime suspend is forbidden by default
(this can be overridden via sysfs, if desired).
These adjustments are needed in order to make ehci-tegra compatible
with recent changes to the USB core. The core now checks the root
hub's status following bus suspend; if the controller is automatically
powered down during bus suspend then the check will fail and the root
hub will be resumed immediately. Doing the controller power-down in a
separate method avoids this problem.

Fixing the locking accidentally replaced a race in the scroll
lock handling with a deadlock. Turn it back into a race for
now.
The basic problem is that there are two paths into the tty
stop/start helpers. One via the tty layer ^S/^Q handling
where we need to take the kbd_event_lock and one via the
special keyboard handler for fn_hold where we already hold
it. Probably we need to split out into a separate LED lock
but for now just go back to the race as it's a bit close
to release.

Bug: The VLAN bit of the MAC RX Status Word is unreliable in several older
supported chips. Sometimes the VLAN bit is not set for valid VLAN packets
and also sometimes the VLAN bit is set for non-VLAN packets that came after
a VLAN packet. This results in a receive length error when VLAN hardware
tagging is enabled.
Fix: Variation on original fix proposed by Mirko.
The VLAN information is decoded in the status loop, and can be
applied to the received SKB there. This eliminates the need for the
separate tag field in the interface data structure. The tag has to
be copied and cleared if packet is copied. This version checked out
with vlan and normal traffic.
Note: vlan_tx_tag_present should be renamed vlan_tag_present, but that
is outside scope of this.

The change to let individual tests decide to reboot the machine on
success of the entire test also prevented errors from rebooting
when an error was detected.
The "no_reboot" variable was only cleared if the test had
reboot_on_success set. But the no_reboot variable also prevents the test
rebooting when an error was detected even when REBOOT_ON_ERROR was set.

When BISECT_REVERSE and BISECT_SKIP are used together with boot or test
testing, build failures are treated as boot or test failures and
'git bisect bad' is executed instead of 'git bisect skip'. This is because
the $ret value of -1 is treated as a build failure, but the $reverse_bisect
logic does not properly handle this.
Simple fix, only invert it if it is positive.
