6ca4350788 ixgbe: Two minor fixes for RSS and FDIR set queues functions
This change fixes two minor issues. The first was the fact that we were
setting the return value to false twice in the set_rss_queues function.
The second is the fact that we should have been using "min_t(int," instead
of "min((int)" in set_fdir_queues.

5407b14c67 gianfar: use netif_tx_queue_stopped instead of __netif_subqueue_stopped
The __netif_subqueue_stopped() just does the following:

        struct netdev_queue *txq = netdev_get_tx_queue(dev, queue_index);
        return netif_tx_queue_stopped(txq);

and since we already have the txq in scope, we can just call that
directly in this case.

729739b754 ixgbe: always write DMA for single_mapped value with skb
This change makes it so that we always write the DMA address for the skb
itself on the same tx_buffer struct that the skb is written on.  This way
we don't need the MAPPED_AS_PAGE flag and we always know it will be the
first DMA value that we will have to unmap.

In addition I have found an issue in which we were leaking a DMA mapping if
the value happened to be 0 which is possible on some platforms.  In order
to resolve that I have updated the transmit path to use the length instead
of the DMA mapping in order to determine if a mapping is actually present.

One other tweak in this patch is that it only writes the olinfo information
on the first descriptor.  As it turns out it isn't necessary to write it
for anything but the first descriptor so there is no need to carry it
forward.

The advantage to this is that the code should just flow a bit more

f800326dca ixgbe: Replace standard receive path with a page based receive
This patch replaces the existing Rx hot-path in the ixgbe driver with a new
implementation that is based on performing a double buffered receive.  The
ixgbe driver already had something similar in place for its' packet split
path, however in that case we were still receiving the header for the
packet into the sk_buff.  The big change here is the entire receive path
will receive into pages only, and then pull the header out of the page and
copy it into the sk_buff data.  There are several motivations behind this
approach.

First, this allows us to avoid several cache misses as we were taking a
set of cache misses for allocating the sk_buff and then another set for
receiving data into the sk_buff.  We are able to avoid these misses on
receive now as we allocate the sk_buff when data is available.

Second we are able to see a considerable performance gain when an IOMMU is
enabled because we are no longer unmapping every buffer on receive.
Instead we can delay the unmap until we are unable to use the page, and
instead we can simply call sync_single_range on the half of the page that
contains new data.

Finally we are able to drop a considerable amount of code from the driver
as we no longer have to support 2 different receive modes, packet split and
one buffer.  This allows us to optimize the Rx path further since less
branching is required.

If host is going to autosuspend function with two interfaces and
if IP packet has arrived in-between of two usbnet_suspend() callbacks,
i.e usbnet_resume() is called in-between, tx data flow is stopped.
When autosuspend timer expires and device is put to autosuspend
again, tx queue is waked up and data can be sent again.
This behavior might be repeated several times in a row.

06d6c10876 netxen: qlogic ethernet : Fix endian bug.
Change the datatype of "ip_addr" to __be32 as 'ip' should be in
big endian format.

Adapter needs "ip address" in big endian format stored at lower 32bit
of req.word[1]. netxen_config_ipaddr() now receives 'ip' in big endian
format. To satisfy adapter's need, use memcpy() to copy byte by byte
of 'ip' into lower 32bit of req.word[1].

Mac address and serial number of adapter need to be in little endian format.

explicitly to __le32 / __le64 depending upon the requirement.

a9e0aca4b3 asix: asix_rx_fixup surgery to reduce skb truesizes
asix_rx_fixup() is complex, and does some unnecessary memory copies (at
least on x86 where NET_IP_ALIGN is 0)

Also, it tends to provide skbs with a big truesize (4096+256 with
MTU=1500) to upper stack, so incoming trafic consume a lot of memory and
I noticed early packet drops because we hit socket rcvbuf too fast.

Switch to a different strategy, using copybreak so that we provide nice
skbs to upper stack (including the NET_SKB_PAD to avoid future head
reallocations in some paths)

With this patch, I no longer see packets drops or tcp collapses on
various tcp workload with a AX88772 adapter.

d8a0f1b0af gianfar: Add support for byte queue limits.
Add support for byte queue limits (BQL), based on the similar
modifications made to intel/igb/igb_main.c from Eric Dumazet
in commit bdbc063129
	"igb: Add support for byte queue limits."

A local variable for tx_queue->qindex was introduced in
gfar_clean_tx_ring, since it is now used often enough to warrant it,
and it cleans up the readability somewhat as well.

377526578f libertas: remove dump_survey implementation
libertas provides a dump_survey implementation based on reading of
a RSSI value. However, this RSSI value is calculated based on the
last received beacon from the associated AP - it is not a good
way of surveying a channel in general, and even causes an error
if the card is not associated to a network.

As this is not appropriate as a survey, remove it. This fixes an
issue where something in userspace is repeatedly calling site-survey
during boot, resulting in many repeated errors as the RSSI value cannot
be read before associating.

that, we can easily loose status, what is not good for rate scaling
algorithm.

is slightly better. Additionally with the patch I can see much less

Tx statuses of aggregated subframes contain packetid of first subframe

simply assume that status match first pending frame in the queue. Thats

f421111b5e rt2x00: rt2800usb: rework txstatus code
Currently we read tx status register after each urb data transfer. As
callback procedure also trigger reading, that causing we have many
"threads" of reading status. To prevent that introduce TX_STATUS_READING
flags, and check if we are already in process of sequential reading
TX_STA_FIFO, before requesting new reads.

Change timer to hrtimer, that make TX_STA_FIFO overruns less possible.
Use 200 us for initial timeout, and then reschedule in 100 us period,
this values probably have to be tuned.

Make changes on txdone work. Schedule it from
rt2800usb_tx_sta_fifo_read_completed() callback when first valid status
show up. Check in callback if tx status timeout happens, and schedule
work on that condition too. That make possible to remove tx status
timeout from generic watchdog. I moved that to rt2800usb.

Loop in txdone work, that should prevent situation when we queue work,
which is already processed, and after finish work is not rescheduled
again.

6b6fa5868e b43: Load firmware from a work queue and not from the probe routine
Recent changes in udev are causing problems for drivers that load firmware
from the probe routine. As b43 has such a structure, it must be changed.
As this driver loads more than 1 firmware file, changing to the asynchronous routine
request_firmware_nowait() would be complicated. In this implementation, the probe
routine starts a queue that calls the firmware loading routines.

a3ea2c76b1 b43legacy: Load firmware from work queue instead of from probe routine
Recent changes in udev are causing problems for drivers that load firmware
from the probe routine. As b43legacy has such a structure, it must be changed.
As this driver loads 3 or 4 firmware files, changing to the asynchronous routine
request_firmware_nowait() would be complicated. In this implementation, the probe
routine starts a work queue that calls the firmware loading routines.
