This patch extends the reporting of the RSS key and hash table by
adding support for X550 VFs. The difference is that X550 VFs have
their own registers for RSS key and indirection table, so there is
no need to query the PF.
The RSS key and indirection table are stored in the adapter structure
during the configuration of VFRSSRK and VFRETA which in turn can be
used in ethtool for reporting.
The logic for writing VFRETA is also changed to make sure that the
indirection table is reported correctly.
In addition this patch adds defines for the VFRETA entries and number
of VFRSSRK registers as well as some whitespace cleanups.

- FCoE traffic might not recover after a failue while there's traffic
to another function.
In addition, this FW opens the door for the driver to implement several

The driver is written as if it can adapt to a low memory situation allocating
less RX skbs and TX aligned buffers than the respective RX/TX ring sizes. In
reality though the driver would malfunction in this case. Stop being overly
smart and just fail in such situation -- this is achieved by moving the memory
allocation from ravb_ring_format() to ravb_ring_init().
We leave dma_map_single() calls in place but make their failure non-fatal
by marking the corresponding RX descriptors with zero data size which should
prevent DMA to an invalid addresses.

If the workaround to support cascaded multicast filters ("workaround_26807") is
enabled, the broadcast filter and individual multicast filters are not inserted
when in promiscuous or allmulti mode.
There is a race while inserting and removing filters when entering and leaving
promiscuous mode. When changing promiscuous state with cascaded multicast
filters, the old multicast filters are removed before inserting the new filters
to avoid duplicating packets; this can lead to dropped packets until all
filters have been inserted.
The efx_nic:mc_promisc flag is added to record the presence of a multicast
promiscuous filter; this gives a simple way to tell if the promiscuous state is
changing.

Intel Wired LAN Driver Updates 2015-07-17
This series contains updates to igb, ixgbe, ixgbevf, i40e, bnx2x,
freescale, siena and dp83640.
Jacob provides several patches to clarify the intended way to implement
both SIOCSHWTSTAMP and ethtool's get_ts_info(). It is okay to support
the specific filters in SIOCSHWTSTAMP by upscaling them to the generic
filters.
Alex Duyck provides a igb patch to pull the time stamp from the fragment
before it gets added to the skb, to avoid a possible issue in which the
fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp
being pulled after the copybreak check. Also provides a ixgbevf patch to
fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives
the advantage that the fragment does not have to be modified after it is
added to the skb.
Fan provides patches for ixgbe/ixgbevf to set the receive hash type
based on receive descriptor RSS type.
Todd provides a fix for igb where on check for link on any media other
than copper was not being detected since it was looking on the incorrect
PHY page (due to the page being used gets switched before the function
to check link gets executed).

We are currently doing a full PHY initialization and even starting the
pHY state machine during bcmgenet_mii_init() which is executed in the
driver's probe function. This is convenient to determine whether we can
attach to a proper PHY device but comes at the expense of spending up to
10ms per MDIO transactions (to reach the waitqueue timeout), which slows
things down.
This also creates a sitaution where we end-up attaching twice to the
PHY, which is not quite correct either.
Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update
its error path accordingly.
Avoid printing the message "attached PHY at address 1 [...]" every time
we bring up/down the interface and remove this print since it duplicates
what the PHY driver already does for us.

Our internal GPHY might be powered off before we attempt scanning the
MDIO bus and bind a driver to it. The way we are currently determining
whether a PHY is internal or not is done *after* we have successfully
matched its driver. If the PHY is powered down, it will not respond to
the MDIO bus, so we will not be able to bind a driver to it.
Our Device Tree for GENET interfaces specifies a "phy-mode" value:
"internal" which tells if this internal uses an internal PHY or not.
If of_get_phy_mode() fails to parse the 'phy-mode' property, do an
additional manual lookup, and if we find "internal" set the
corresponding internal variable accordingly.
Replace all uses of phy_is_internal() with a check against
priv->internal_phy to avoid having to rely on whether or not
priv->phydev is set correctly.

phy_resume() takes care of re-apply our workarounds in case we need any,

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.

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.
