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.Signed-off-by: Scott Feldman

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

* 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.Signed-off-by: Govindarajulu Varadarajan

====================
Intel Wired LAN Driver Updates 2015-07-14This 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.Signed-off-by: Claudiu Manoil

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.Signed-off-by: Claudiu Manoil

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

Due to an inverted conditional, the driver was marking all of its MAC

Commit 514ac99c64b "can: fix multiple delivery of a single CAN frame for
overlapping CAN filters" requires the skb->tstamp to be set to check for
identical CAN skbs.Without timestamping to be required by user space applications this timestamp
was not generated which lead to commit 36c01245eb8 "can: fix loss of CAN frames
in raw_rcv" - which forces the timestamp to be set in all CAN related skbuffs
by introducing several __net_timestamp() calls.This forces e.g. out of tree drivers which are not using alloc_can{,fd}_skb()
to add __net_timestamp() after skbuff creation to prevent the frame loss fixed
in mainline Linux.This patch removes the timestamp dependency and uses an atomic counter to
create an unique identifier together with the skbuff pointer.Btw: the new skbcnt element introduced in struct can_skb_priv has to be
initialized with zero in out-of-tree drivers which are not using
alloc_can{,fd}_skb() too.Signed-off-by: Oliver Hartkopp

Since commit ab78029 (drivers/pinctrl: grab default handles from device core),
the device core will automatically set the default pins. This causes the pins
to be momentarily set to the default and then to the sleep state in
register_c_can_dev(). By adding an optional "enable" state, boards can set the
default pin state to be disabled and avoid the glitch when the switch from
default to sleep first occurs. If the "enable" state is not available
c_can_pinctrl_select_state() falls back to using the "default" pinctrl state.[Roger Q] - Forward port to v4.2 and use pinctrl_get_select().
