This patch makes TLP to use 1 sec timer by default when RTT is
not available due to SYN/ACK retransmission or SYN cookies.
Prior to this change, the lack of RTT prevents TLP so the first
data packets sent can only be recovered by fast recovery or RTO.
If the fast recovery fails to trigger the RTO is 3 second when
SYN/ACK is retransmitted. With this patch we can trigger fast
recovery in 1sec instead.
Note that we need to check Fast Open more properly. A Fast Open
connection could be (accepted then) closed before it receives
the final ACK of 3WHS so the state is FIN_WAIT_1. Without the
new check, TLP will retransmit FIN instead of SYN/ACK.

Currently SYN/ACK RTT is measured in jiffies. For LAN the SYN/ACK
RTT is often measured as 0ms or sometimes 1ms, which would affect
RTT estimation and min RTT samping used by some congestion control.
This patch improves SYN/ACK RTT to be usec resolution if platform
supports it. While the timestamping of SYN/ACK is done in request
sock, the RTT measurement is carefully arranged to avoid storing
another u64 timestamp in tcp_sock.
For regular handshake w/o SYNACK retransmission, the RTT is sampled
right after the child socket is created and right before the request
sock is released (tcp_check_req() in tcp_minisocks.c)
For Fast Open the child socket is already created when SYN/ACK was
sent, the RTT is sampled in tcp_rcv_state_process() after processing
the final ACK an right before the request socket is released.
If the SYN/ACK was retransmistted or SYN-cookie was used, we rely
on TCP timestamps to measure the RTT. The sample is taken at the
same place in tcp_rcv_state_process() after the timestamp values
are validated in tcp_validate_incoming(). Note that we do not store
TS echo value in request_sock for SYN-cookies, because the value
is already stored in tp->rx_opt used by tcp_ack_update_rtt().
One side benefit is that the RTT measurement now happens before
initializing congestion control (of the passive side). Therefore
the congestion control can use the SYN/ACK RTT.

s390: qeth and iucv patches
here is version 2 of some s390 related qeth patches for net-next. The patch by
Thomas Richter adds a new feature to the qeth layer2 code; the remaining
patches are minor improvements.
Version 2 of patch 4 uses the desired indentation in function declarations
and definitions spanning multiple lines in almost all cases. Thomas run into a
conflict with the maximum number of columns once. Thus you will still see one
function definition using an earlier column before the opening paranthesis.

The iucv code uses arrays as arguments. Even though this does not

Checksum offloading for send and receive is already
supported for layer 3 (IP layer). This patch
adds support for RX and TX hardware checksum offloading
for layer 2 (MAC layer). The hardware calculates the checksum
for IP UDP and TCP packets.
This patch moves the hardware checksum offloading setup
to the set of common functions in qeth_core_main.c.
Layer 2 and layer 3 now simply call the same common functions.
Also note that TX checksum offloading is always enabled.
The device driver relies on the TCP/IP stack to make use of
this feature.

Intel Wired LAN Driver Updates 2015-09-17
This series contains updates to i40e and i40evf.
Shannon provides updates to i40e and i40evf to resolve an issue with the
nvmupdate utility. First renames a variable name to reduce confusion and
to differentiate it from the actual user variable. Then added the ability
to save the admin queue write back descriptor if a caller supplies a
buffer for it to be saved into. Added a new GetStatus command so that
the NVM update tool can query the current status instead of doing fake
write requests to probe for readiness. Added wait states to the NVM
update state machine to signify when waiting for an update operation to
finish, whether we are in the middle of a set of write operations, or we
are now idle but waiting. Then added a facility to run admin queue
commands through the NVM update utility in order to allow the update
tools to interact with the firmware and do special commands needed for
updates and configuration changes. Also added a facility to recover the
result of a previously run admin queue command.

The Hisilicon Network Subsystem is a long term evolution IP which is
supposed to be used in Hisilicon ICT SoC. The IP, which is called hns
for short, is a TCP/IP acceleration engine, which can directly decode
TCP/IP stream and distribute them to different ring buffers.
HNS can be configured to work on different mode for different scenario.
This patch make use only some of the mode to make it as standard
ethernet NIC. The other mode will be added soon.
The whole function has 4 kernel sub-modules:
hnae: the HNS acceleration engine framework. It provides a abstract
interface between the engine and the upper layers which make use of the
engine by ring buffer.
hns_enet_drv: a standard ethernet driver that base on the ring buffer.
hns_dsaf: one of the implementation of HNS acceleration engine, which is
applied on Hililicon hip05, Hi1610 and other later-on SoCs
hns_mdio: the mdio control to the PHY, used by acceleration engine

To support this create an nf_hook_state on the stack in ebt_broute
