Intel Wired LAN Driver Updates 2015-01-22

This series contains updates to e1000, e1000e, igb, fm10k and virtio_net.

Asaf Vertz provides a fix for e1000 to future-proof the time comparisons
by using time_after_eq() instead of plain math.

Mathias Koehrer provides a fix for e1000e to add a check to e1000_xmit_frame()
to ensure a work queue will not be scheduled that has not been initialized.

Jacob adds the use of software timestamping via the virtio_net driver.

Alex Duyck cleans up page reuse code in igb and fm10k.  Cleans up the
page reuse code from getting into a state where all the workarounds
needed are in place as well as cleaning up oversights, such as using
__free_pages instead of put_page to drop a locally allocated page.

Richard Cochran provides 4 patches for igb dealing with time sync.
First provides a helper function since the code that handles the time
sync interrupt is repeated in three different places.  Then serializes
the access to the time sync interrupt since the registers may be
manipulated from different contexts.  Enables the use of i210 device
interrupt to generate an internal PPS event for adjusting the kernel
system time.  The i210 device offers a number of special PTP hardware
clock features on the Software Defined Pins (SDPs), so added support for
two of the possible functions (time stamping external events and
periodic output signals).

Or Gerlitz fixes fm10k from double setting of NETIF_F_SG since the
networking core does it for the driver during registration time.

Joe Stringer adds support for up to 104 bytes of inner+outer headers in
fm10k and adds an initial check to fail encapsulation offload if these
are too large.

Matthew increases the timeout for the data path reset based on feedback
from the hardware team, since 100us is too short of a time to wait for
the data path reset to complete.

Alexander Graf provides a fix for igb to indicate failure on VF reset
for an empty MAC address, to mirror the behavior of ixgbe.

Florian Westphal updates e1000 and e1000e to support txtd update delay
via xmit_more, this way we won't update the Tx tail descriptor if the
queue has not been stopped and we know at least one more skb will be
sent right away.

vxlan: Don't use UDP socket for transmit

UDP socket is not pertinent to transmit for UDP tunnels, checksum
enablement can be done without a socket. This patch set eliminates
reference to a socket in udp_tunnel_xmit functions and in VXLAN
transmit.

Also, make GBP, RCO, can CSUM6_RX flags visible to receive socket
and only match these for shareable socket.

In the vxlan transmit path there is no need to reference the socket
for a tunnel which is needed for the receive side. We do, however,
need the vxlan_dev flags. This patch eliminate references
to the socket in the transmit path, and changes VXLAN_F_UNSHAREABLE
to be VXLAN_F_RCV_FLAGS. This mask is used to store the flags
applicable to receive (GBP, CSUM6_RX, and REMCSUM_RX) in the
vxlan_sock flags.

The UDP tunnel transmit functions udp_tunnel_xmit_skb and
udp_tunnel6_xmit_skb include a socket argument. The socket being
passed to the functions (from VXLAN) is a UDP created for receive
side. The only thing that the socket is used for in the transmit
functions is to get the setting for checksum (enabled or zero).
This patch removes the argument and and adds a nocheck argument
for checksum setting. This eliminates the unnecessary dependency
on a UDP socket for UDP tunnel transmit.

There have one bug in .fec_enet_tx_queue() function to unmap the DMA memory:
For SG or TSO, get one buffer descriptor and then unmap the related DMA memory, and then
get the next buffer descriptor, loop to while() to check "TX_READY". If "TX_READY" bit
still __IS__ existed in the BD (The next fraglist or next TSO packet is not transmited
complitely), exit the current clean work. When the next work is triggered, it still repeat
above step with the same BD. The potential issue is that unmap the same DMA memory for
multiple times.

The patch fix the clean work for SG and TSO packet.

be2net: patch set

Hi David, as the below patch-set includes minor bug fixes and some
code re-org, pls consider applying it to the "net-next" tree. Thanks!

Patch 1 fixes a bit of code duplication involving interface object
creation code.

Patch 2 ensures that when a flow-control FW cmd fails, the adapter state
continues to reflect the old values. This allows for correct reporting
on subsequent ethtool "get".

Patch 3 returns proper error for link config change on BE3/Lancer

Patch 4 adds a kernel log message for FW boot error on Lancer

Patch 5 adds a function reset on Lancer as a part of the function init
sequence.

Patch 6 moves some FW-cmd definitions that belong in be_cmds.h, but
were placed in be_hw.h

Patch 7 resets the "bw_min" field while configuring "bw_max" needed
for TX rate limiting config.

net: stmmac: dwmac-rk: Fix phy regulator issues

This series fixes few issues in dwmac-rk:

1. Voltage settings was hardcoded into the driver for the phy regulator.
   The driver now uses the default voltage settings found in the devicetree,
   which are applied throught the regulator framework.
2. The regulator name used to power on or power off the phy was put in the devicetree
   variable "phy_regulator", which is not standard and added a lot of code for nothing.
   The driver now uses the devicetree property "phy-supply" and the corresponding functions
   to manipulate this regulator.

The corresponding devicetree files are also updated. As this new binding for
rk3288 has not been released with any official kernel yet (not until 3.20),
I don't need to care about keeping compatibility with the old non standard property.

Currently, dwmac-rk uses a custom propety "phy_regulator" to get the name of the
right regulator to use to power on or power off the phy. This commit converts the
driver to use phy-supply devicetree property and the corresponding API, it cleans
the code a bit and make it simpler to maintain. This also replaces the property
phy_regulator by the standard property phy-supply in rk3288-evb-rk808.dts.

Always fully coalesce guest Rx packets into the minimum number of ring
slots.  Reducing the number of slots per packet has significant
performance benefits when receiving off-host traffic.

Results from XenServer's performance benchmarks:

                         Baseline    Full coalesce
Interhost VM receive      7.2 Gb/s   11 Gb/s
Interhost aggregate      24 Gb/s     24 Gb/s
Intrahost single stream  14 Gb/s     14 Gb/s
Intrahost aggregate      34 Gb/s     34 Gb/s

However, this can increase the number of grant ops per packet which
decreases performance of backend (dom0) to VM traffic (by ~10%)
/unless/ grant copy has been optimized for adjacent ops with the same
source or destination (see "grant-table: defer releasing pages
acquired in a grant copy"[1] expected in Xen 4.6).
