Don't do the num_tx_queues based masking on calculating tx queue
index.

 1) num_tx_queues is not always power-of-2, because it also depends on
    the online cpu numbers. So the masking could be a performance bug
    on a 6 cpu system.
 2) queue_mapping will be limited by real_num_tx_queues=num_tx_queues
    in the generic netdev function set_cur_queue_map(). So the bound
    limiting here is not necessary.

This reverts commit 244f46ae.

Alan Cox did the research, and just like the other radio protocols
zero-length frames have meaning because at the top level ROSE is
X.25 PLP.

So this zero-length filtering is invalid.

falcon_sim_phy_event() used EFX_OWORD_FIELD, which operates on
bitfields in 128-bit values, on an event, which is a 64-bit value.
This should be harmless - these macros always use little-endian
ordering, so it would read and write back the following 8 bytes
unchanged - but it is obviously wrong.

sfc could call netif_napi_add() multiple times for the same
napi_struct, corrupting the list of napi_structs for the associated
device and leading to a busy-loop on device removal.  Move the call to
netif_napi_add() and add a call to netif_napi_del() in the obvious
places.

The BUG_ON(skge->tx_ring.to_use != skge->tx_ring.to_clean) in skge_up()
was sometimes observed when setting MTU.

skge_down() disables the TX queue, but then reenables it by mistake via
skge_tx_clean().
Fix it by moving the waking of the queue from skge_tx_clean() to the
other caller. And to make sure start_xmit is not in progress on another
CPU, skge_down() should call netif_tx_disable().

The bug was reported to me by Jiri Jilek whose Debian system sometimes
failed to boot. He tested the patch and the bug did not happen anymore.

When I made the tun driver use non-linear packets as the preferred
option, it broke non-GSO users because they would end up allocating
a completely non-linear packet, which triggers a crash when we call
eth_type_trans.

This patch reverts non-GSO users to using linear packets and adds
a check to ensure that GSO users can't cause crashes in the same
way.

Hi:

gro: Normalise skb before bypassing GRO on netpoll VLAN path

When we detect netpoll RX on the GRO VLAN path we bail out and
call the normal VLAN receive handler.  However, the packet needs
to be normalised by calling eth_type_trans since that's what the
normal path expects (normally the GRO path does the fixup).

This patch adds the necessary call to vlan_gro_frags.

Marvell 88E1121R Dual PHY device can be hardware-configured
to use shared interrupt pin for both PHY ports. For such
PHY configurations using shared PHY interrupt phy_interrupt()
handler will also schedule a work for PHY port which didn't
cause an interrupt.

This patch adds a possibility for PHY drivers to provide
did_interrupt() function which reports if the PHY (or a PHY
port in a multi-PHY device) generated an interrupt. This
function is called in phy_change() as phy_change() shouldn't
proceed if it is invoked for a PHY which didn't cause an
interrupt. So check for interrupt originator in phy_change()
to allow early-out.

We noticed on parisc that our broadcoms all swapped MAC addresses going

The problem patch is:

commit 6d348f2c
Author: Matt Carlson <mcarlson@broadcom.com>
Date:   Wed Feb 25 14:25:52 2009 +0000

    tg3: Eliminate tg3_nvram_read_swab()

With the root cause being the use of memcpy to set the mac address:

   memcpy(&dev->dev_addr[0], ((char *)&hi) + 2, 2);
   memcpy(&dev->dev_addr[2], (char *)&lo, sizeof(lo));

This might work on little endian machines, but it can't on big endian
ones.  You have to use the original setting mechanism to be correct on
all architectures.

The attached patch fixes parisc.

There is a race between resume from hibernation and the asynchronous
scanning of SCSI devices and to prevent it from happening we need to
call scsi_complete_async_scans() during resume from hibernation.

In addition, if the resume from hibernation is userland-driven, it's
better to wait for all device probes in the kernel to complete before
attempting to open the resume device.
