The keystone qmss will raise interrupt when packet arrive at the
receive queue. Only control available to avoid interrupt from happening
is to keep the free descriptor queue (FDQ) empty in the receive side.
So the filling of descriptors into the FDQ has to happen after
request_irq() call is made as part of knav_queue_enable_notify(). So
move the function netcp_rxpool_refill() after this call.

If device flags ingress packet as "fwd offload", mark the
skb->offlaod_fwd_mark using the ingress port's dev->offlaod_fwd_mark. This
will be the hint to the kernel that this packet has already been forwarded
by device to egress ports matching skb->offlaod_fwd_mark.
For rocker, derive port dev->offlaod_fwd_mark based on device switch ID and
port ifindex. If port is bridged, use the bridge ifindex rather than the
port ifindex.

Teach rocker to forward packets to CPU when a port is joined to Open vSwitch.
There is scope to later refine what is passed up as per Open vSwitch flows
on a port.
This does not change the behaviour of rocker ports that are
not joined to Open vSwitch.

* Allow setting of adaptive coalescing setting for all types of interrupt.
* In msi & legacy intr, we use single interrupt for rx & tx. In this case
tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs.
Do not display tx_coal values for msi/intx. And do not allow user to set
this as well.
* Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings.
For other values, driver does not return error. So ethtool succeeds for
unsupported values. Introduce enic_coalesce_valid() function to validate
the coalescing values.
* If user requests for coalesce value greater than what adaptor supports,
driver uses the max value. We should at least log this.

Adaptive interrupt coalescing is available for msix. This patch adds the support
for msi poll. Interface for adaptive interrupt coalescing is already added in
driver. We just did not enable it for legacy intr & msi.
enic_calc_int_moderation() & enic_set_int_moderation() are defined as static
after enic_poll. Since enic_poll needs it, move both of these function
definitions above enic_poll. No change in functionality.

- fix an incorrect overly restrictive ifdef
- select O32 64-bit FP support for O32 binary compatibility
- remove workarounds for Sibyte SB1250 Pass1 parts. There are rare
fixing the workarounds is not worth the effort.
- patch up an outdated and now incorrect comment"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: fpu.h: Allow 64-bit FPU on a 64-bit MIPS R6 CPU
MIPS: SB1: Remove support for Pass 1 parts.

page 1 for "other" (fiber) link. The switch back from page 1 to page 0
happened too soon, before e1000_check_for_link_82575() is executed, and
link on fiber (other) was never detected. Check for link while still on

For two reasons I want to disable this:
1. Not any part actually check the report status(Alexander Duyck)
2. To report hash value of a packet to stack,
RSS -> 32bits hash value
Perfect match fdir filter -> 13bits hash value
Hashed-based fdir filter -> 31bits hash value
fdir filter might hash on masked tuples for IP address,
so it's still not desirable for usage.
So for now, just stick to RSS 32bits hash value.

This change makes it so that we pull the timestamp from the fragment before
we add it to the skb. By doing this we can avoid a possible issue in which
the fragment can possibly be less than IGB_RX_HDR_LEN due to the timestamp
being pulled after the copybreak check.
While making this change I realized we could also pull the rest of the
igb_pull_tail function into igb_add_rx_frag since in the case of igb,
unlike ixgbe, we are able to unmap the entire buffer before calling
add_rx_frag so merging the two allows for sharing of code between the two
merged functions.

First, dma_sync_single_for_cpu() shouldn't have been called in the first place
(it's a streaming DMA API), dma_unmap_single() should have been called instead.
Second, dma_unmap_single() call after handing the buffer to napi_gro_receive()

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2015-07-14
This series contains updates to i40e and i40evf only.
Joe Stringer and Jesse Gross add a ndo_features_check function to ensure
that the i40e driver does not try to offload packets that exceed 80 bytes
in length.
Anjali adds additional stats to track flow director ATR and SB current
state and flow director flush count which will help the need for verbose
debug logs with respect to flow director. Also refines an error message
to avoid confusion, so that it indicates what may have really happened
when the init_shared_code() call possibly fails.
Pawel adds new fields to the capabilities structures to handle Flex-10
device/function capabilities which is needed to support Flex-10 configs.
Jesse improves the transmit performance by added a prefetch for the
next transmit descriptor to be used when we know there are more coming.
Mitch modifies i40evf driver to handle/allow an abundance of vectors.
Currently the driver only maps transmit and receive queues to a single
MSI-X vector per queue if there are exactly enough vectors for this, but
if we have too many vectors, it will fail and allocate queues to vectors
in a suboptimal manner. So change the condition check to allow for an
excess number of vectors and won't use the extras. Also update the
driver to just return success if the user attempts to set a port VLAN on
a VF that already has the same port VLAN configured, instead of going
through unnecessary filter removals & adds. Fix the MAC filters for VFs,
which were being programmed with 0 for the VLAN value when there was no
VLAN assigned. Instead, we must use -1 to indicate that no VLAN is in
use. Fix the VF disable code, which was not properly cleaning up the VF
and would leave the VF in an indeterminate state, so fix this by
notifying the VF and then call the normal VF reset routine. Fix the
logic in the driver so that MAC filters are added and removed correctly
and added a check for the driver's hardware MAC address so that this
filter does not get removed incorrectly.
Carolyn removes incorrect #ifdef's which should not have been added in
the first place and with the #ifdef's removed, make the necessary
changes in the driver to resolve compile errors.
Greg updates the admin queue command header defines.

The eTSEC h/w is capable of scatter/gather on the receive side
too if MAXFRM > MRBLR, when the allowed maximum Rx frame size
is set to be greater than the maximum Rx buffer size (MRBLR).
It's about time the driver makes use of this h/w capability,
by supporting fixed buffer sizes and Rx S/G.
The buffer size given to eTSEC for reception is fixed to
1536B (must be multiple of 64), which is the same default
buffer size as before, used to accommodate standard MTU
(1500B) size frames. As before, eTSEC can receive frames of
up to 9600B. Individual Rx buffers are mapped to page halves
(page size for eTSEC systems is 4KB). The skb is built around
the first buffer of a frame (using build_skb()). In case the
frame spans multiple buffers, the trailing buffers are added
as Rx fragments to the skb. The last buffer in frame is marked
by the L status flag. A mechanism is in place to reuse the pages
owned by the driver (for Rx) for subsequent receptions.
Supporting fixed size buffers allows the implementation of Rx S/G,
which in turn removes the memory pressure issues the driver had
before when MTU was set for jumbo frame reception.
Also, in most cases, the Rx path becomes faster due to Rx page
reusal, since the overhead of allocating new rx buffers is removed
from the fast path.

There are several (long standing) problems about how the status
field of the rx buffer descriptor (rxbd) is currently handled on
the error path:
- too many unnecessary 16bit reads of the two halves of the rxbd
status field (32bit), also resulting in overuse of endianness
convesion macros;
- "bdp->status = RXBD_LARGE" makes no sense, since the "large"
flag is read only (only eTSEC can write it), and trying to clear
the other status bits is also error prone in this context
(most of the rx status bits are read only anyway).
This is fixed with a single 32bit read of the "status" field,
and then the appropriate 16bit shifting is applied to access
the various status bits or the rx frame length. Also corrected
the use of the RXBD_LARGE flag.
Additional fix:
"rx_over_errors" stat is incremented instead of "rx_crc_errors"
in case of RXBD_OVERRUN occurrence.

Use a more common consumer/ producer index design to improve
rx buffer allocation. Instead of allocating a single new buffer
(skb) on each iteration, bundle the allocation of several rx
buffers at a time. This also opens the path for further memory
optimizations.
Remove useless check of rxq->rfbptr, since this patch touches
rx pause frame handling code as well. rxq->rfbptr is always
initialized as part of Rx BD ring init.
Remove redundant (and misleading) 'amount_pull' parameter.

Due to an inverted conditional, the driver was marking all of its MAC
filters for deletion every time set_rx_mode was called. Depending upon
the timing of the calls to set_rx_mode and the processing of the admin

functional filters.
Correct this logic so that MAC filters are added and removed correctly.

The driver currently only maps TX and RX queues to a single MSI-X vector
per queue pair if there are exactly enough vectors for this.
Unfortunately, if we have too many vectors it will fail and allocate

Some of the local variable intializers in the driver turned out to be pointless,
kill them.

Pass 1 parts had a number of significant erratas and were only available
in small numbers and under NDA. Full support also required the use of a
special toolchain that kept branches properly aligned. These workarounds
were never upstreamed and the only toolchain known to have them is
Montavista's GCC 3.0-based toolchain which completly obsoleted if not
useless these days.
So now that automated testing has tripped over the user of the
-msb1-pass1-workarounds option, rather than fixing it remove support for
pass 1 parts.
Probably nobody will notice. I seem to own the last know pass 1 board
and I haven't noticed another one in the wild in the past decade, at
least.

Conflicts:
net/bridge/br_mdb.c
Minor conflict in br_mdb.c, in 'net' we added a memset of the
on-stack 'ip' variable whereas in 'net-next' we assign a new
member 'vid'.

bcmgenet driver needs to separate packet drops from packet errors.
When the driver has to drop a *good* packet, due to lack of buffers or
replacement skbs, increment only dev->stats.[rx|tx]_dropped.
When the driver encounters a bad Rx packet or Tx error, increment only
dev->stats.[rx|tx]_errors + relevant detailed error counter.
