Marc Kleine-Budde says:
====================
another pull-request for net-next. It consists of two patches by Libo
Chen, the at91 and flexcan driver make use of platform_set_drvdata()
rather than open coding it. Chen Gang improves the error checking in
the c_can_platform driver's probe function.

IP sends device configuration (see inet_fill_link_af) as an array
in the netlink information, but the indices in that array are not
exposed to userspace through any current santized header file.
It was available back in 2.6.32 (in /usr/include/linux/sysctl.h)
but was broken by:

net ipv4: Decouple ipv4 interface parameters from binary sysctl numbers
Eric was solving the sysctl problem but then the indices were re-exposed
by a later addition of devconf support for IPV4

rfc 4861 says the Redirected Header option is optional, so

ip6_redirect_no_header() is introduced to deal with that

commit fba875591 ("disable TX in be_close()") disabled TX in be_close()
to protect be_xmit() from touching freed up queues in the AER recovery
flow. But, TX must be disabled *before* cleaning up TX completions in
the close() path, not after. This allows be_tx_compl_clean() to free up
all TX-req skbs that were notified to the HW.

The tcp_probe currently only supports analysis of IPv4 connections.
Therefore, it would be nice to have IPv6 supported as well. Since we
have the recently added %pISpc specifier that is IPv4/IPv6 generic,
build related sockaddress structures from the flow information and
pass this to our format string. Tested with SSH and HTTP sessions
on IPv4 and IPv6.

This patches fixes a rather unproblematic function signature mismatch
as the const specifier was missing for the th variable; and next to
that it adds a build-time assertion so that future function signature
mismatches for kprobes will not end badly, similarly as commit 22222997
("net: sctp: add build check for sctp_sf_eat_sack_6_2/jsctp_sf_eat_sack")
did it for SCTP.

It is helpful to sometimes know the TCP window sizes of an established
socket e.g. to confirm that window scaling is working or to tweak the
window size to improve high-latency connections, etc etc. Currently the
TCP snooper only exports the send window size, but not the receive window
size. Therefore, also add the receive window size to the end of the
output line.

The stack currently detects reordering and avoid spurious
retransmission very well. However the throughput is sub-optimal under
high reordering because cwnd is increased only if the data is deliverd
in order. I.e., FLAG_DATA_ACKED check in tcp_ack(). The more packet
are reordered the worse the throughput is.
Therefore when reordering is proven high, cwnd should advance whenever
the data is delivered regardless of its ordering. If reordering is low,
conservatively advance cwnd only on ordered deliveries in Open state,
and retain cwnd in Disordered state (RFC5681).
Using netperf on a qdisc setup of 20Mbps BW and random RTT from 45ms
to 55ms (for reordering effect). This change increases TCP throughput
by 20 - 25% to near bottleneck BW.
A special case is the stretched ACK with new SACK and/or ECE mark.
For example, a receiver may receive an out of order or ECN packet with
unacked data buffered because of LRO or delayed ACK. The principle on
such an ACK is to advance cwnd on the cummulative acked part first,
then reduce cwnd in tcp_fastretrans_alert().

Intel Wired LAN Driver Updates
This series contains updates to igb and e1000e.
Akeem provides 3 igb patches, the first resets the link when EEE is enabled
or disabled if the link is up. His second patch changes a register read
which normally stores of the read value to "just-read" so that hardware
can accurately latch the register read. Lastly, he adds rcu_lock to avoid
a possible race condition with igb_update_stats function.
Mitch provides a fix for SR-IOV, where MSI-X interrupts are required, so
make sure that MSI-X is enabled before allowing the user to turn on SR-IOV.
Alex's igb patch make it so that we limit the lower bound for max_frame_size
to the size of a standard Ethernet frame. This allows for feature parity
with other Intel based drivers such as ixgbe.
Carolyn adds a SKU for a flashless i210 device and a fix for get_fw_version()
so that it works for all parts for igb. In addition, she has 2 igb patches
to refactor NVM code to accommodate devices with no flash. Lastly, she
adds code to check for the failure of pci_disable_link_state() to attempt
to work around a problem found with some systems.
Laura provides the remaining 2 igb patches. One removing the hard-coded
value for the size of the RETA indirection table, and creates a macro instead
for the RETA indirection table. The second adds the ethtool callbacks
necessary to change the RETA indirection table from userspace.
Bruce fixes a whitespace issue in a recent commit and resolves a jiffies
comparison warning by using time_after().
Li provides a fix for e1000e to avoid a kernel crash on shutdown by adding
one more check in e1000e_shutdown(). This is due to e1000e_shutdown()
trying to clear correctable errors on the upstream P2P bridge, when under
some cases we do not have the upstream P2P bridge.
v2:
- fixed patch 11 conditional statement from < to <= based on feedback
from Ben Hutchings
- fixed patch 12 patch description (adding the commit summary) based
on feedback from Sergei Shtylyov

Bug 60747 - 1286:2044 [Microsoft Surface Pro]
Marvell 88W8797 wifi show 3 interface under network
https://bugzilla.kernel.org/show_bug.cgi?id=60747
This issue was also reported previously by OLPC and some folks from
the community.
There are 3 network interfaces with different types being created
when mwifiex driver is loaded:
1. mlan0 (infra. STA)
2. uap0 (AP)
3. p2p0 (P2P_CLIENT)
The Network Manager attempts to use all 3 interfaces above without
filtering the managed interface type. As the result, 3 identical
interfaces are displayed under network manager. If user happens to
click on an entry under which its interface is uap0 or p2p0, the
association will fail.
Work around it by removing the creation of AP and P2P interfaces
at driver loading time. These interfaces can be added with 'iw' or
other applications manually when they are needed.

Currently we use struct efx_mtd to represent a physical NVRAM device
and struct efx_mtd_partition to represent a partition on that device.
But this only really makes sense for Falcon, as we don't know or care
whether MC-managed NVRAM partitions are on one or more physical
devices. It complicates iteration and provides little benefit.
Therefore:
- Replace the pointer to efx_mtd in mtd_info::priv with a pointer to efx_nic
- Move the falcon_spi_device pointer into the union in struct efx_mtd_partition
- Move the device name to efx_mtd_partition::dev_type_name
- Move the efx_mtd_ops pointer to efx_nic::mtd_ops
- Make efx_nic::mtd_list a list of partitions

On Falcon we implement MAC filtering requested by the stack using the
MAC wrapper's single unicast filter and multicast hash filter. Siena
is very similar, though MAC configuration is mediated by the MC.
Since MCDI operations may sleep, reconfiguration is deferred from
ndo_set_rx_mode to a work item. However, it still updates the private
variables describing the filter state synchronously. Contrary to
comments, the later use of these variables is not protected using the
address lock, resulting in race conditions.
Move the state update to a new function
efx_farch_filter_sync_rx_mode() and make the Falcon-arch MAC
configuration functions call that, so that its use is consistently
serialised by the mac_lock.
Invert and rename the promiscuous flag to the more accurate
unicast_filter, and comment that both this and multicast_hash are
not used on EF10.

MAC filters inserted on request from the stack (ndo_set_rx_mode)
should allow manual steering but not removal. Currently we have a
special case for Siena's all-multicast and all-unicast MAC filters,
but on EF10 we need to allow for steering of precise MAC filters as
well.
The EFX_FILTER_FLAG_RX_STACK flag changes the behaviour of replacement
and removal requests:
- Replacement *of* a filter with this flag never clears the flag but
does change steering and saved priority
- Replacement *by* a filter with this flag only sets the flag but does
not change steering
- Removal with priority < EFX_FILTER_PRI_REQUIRED really resets RX
steering and saved priority
This could support precise MAC filtering on Siena in future.
As a side-benefit, the default MAC filters are hidden from ethtool
until they are steered.
