tcp_adv_win_scale default value is 2, meaning we expect a good citizen
skb to have skb->len / skb->truesize ratio of 75% (3/4)

In 2.6 kernels we (mis)accounted for typical MSS=1460 frame :
1536 + 64 + 256 = 1856 'estimated truesize', and 1856 * 3/4 = 1392.
So these skbs were considered as not bloated.

With recent truesize fixes, a typical MSS=1460 frame truesize is now the
more precise :
2048 + 256 = 2304. But 2304 * 3/4 = 1728.
So these skb are not good citizen anymore, because 1460 < 1728

(GRO can escape this problem because it build skbs with a too low
truesize.)

This also means tcp advertises a too optimistic window for a given
allocated rcvspace : When receiving frames, sk_rmem_alloc can hit
sk_rcvbuf limit and we call tcp_prune_queue()/tcp_collapse() too often,
especially when application is slow to drain its receive queue or in
case of losses (netperf is fast, scp is slow). This is a major latency
source.

We should adjust the len/truesize ratio to 50% instead of 75%

This patch :

1) changes tcp_adv_win_scale default to 1 instead of 2

2) increase tcp_rmem[2] limit from 4MB to 6MB to take into account
better truesize tracking and to allow autotuning tcp receive window to
reach same value than before. Note that same amount of kernel memory is
consumed compared to 2.6 kernels.

I just noticed after some recent updates, that the init path for the drop
monitor protocol has a minor error.  drop monitor maintains a per cpu structure,
that gets initalized from a single cpu.  Normally this is fine, as the protocol
isn't in use yet, but I recently made a change that causes a failed skb
allocation to reschedule itself .  Given the current code, the implication is
that this workqueue reschedule will take place on the wrong cpu.  If drop
monitor is used early during the boot process, its possible that two cpus will
access a single per-cpu structure in parallel, possibly leading to data
corruption.

This patch fixes the situation, by storing the cpu number that a given instance
of this per-cpu data should be accessed from.  In the case of a need for a
reschedule, the cpu stored in the struct is assigned the rescheule, rather than
the currently executing cpu

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

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.

Contrary to what lockdep says, the code is not fine: we are locking an
uninitialized spinlock.

With the support to bounce buffer added, the skb is coming as nonlinear in the
case of non-DDPed data frames for FCoE, which is mostly ok as the FCoE stack
would take care of that. However, for target mode, we have to set the FC CRC
and FC EOF field to allow the protocol stack to not drop the frame for the last
data frame of that sequence. So fix this by linearizing the skb first before
doing skb_put().

The driver was freeing memory in shutdown instead of remove.  As a result
we were leaking memory if IEEE DCB was enabled and we loaded/unloaded the
driver.  This change moves the freeing of the memory into the remove
routine where it belongs.

This patch sets the automatic speed and duplex detection bits
in MAC_CR to enable the mac to determine its speed automatically
from the phy.

Note this must be done BEFORE the receiver or transmitter is
enabled.

This patch fixes the same issue as reported on smsc95xx, where the
usb device is connected with no ethernet cable plugged-in.

Without this patch sysfs reports the cable as present
