Here are two tty serial driver fixes for 4.13-rc5. One is a revert of a
-rc1 patch that turned out to not be a good idea, and the other is a fix
for the pl011 serial driver.
Both have been in linux-next with no reported issues.

When CONFIG_NET_SCHED or CONFIG_NET_RX_BUSY_POLL is /not/ set and

then verifier rightfully complains that it's misconfigured, because
we need to set target_size in each of the two cases. The rewrite

The Flower app may receive a request to update the MTU of a representor

the RTNL lock which needs to be taken outside of the packet processing
path.
As a handling of this correctly seems a little to invasive for a fix simply
skip setting the MTU for now.

Attempts to connect to a local address with a socket bound
to a device with the local address hangs if there is no listener:
$ ip addr sh dev eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 02:e0:f9:1c:00:37 brd ff:ff:ff:ff:ff:ff

$ vrf-test -I eth1 -r 10.100.1.4
<hangs when there is no server>
(don't let the command name fool you; vrf-test works without vrfs.)
The problem is that the original intended device, eth1 in this case, is
lost when the tcp reset is sent, so the socket lookup does not find a
match for the reset and the connect attempt hangs. Fix by adjusting
orig_oif for local traffic to the device from the fib lookup result.
With this patch you get the more user friendly:
$ vrf-test -I eth1 -r 10.100.1.4
connect failed: 111: Connection refused
orig_oif is saved to the newly created rtable as rt_iif and when set
it is used as the dif for socket lookups. It is set based on flowi4_oif
passed in to ip_route_output_key_hash_rcu and will be set to either
the loopback device, an l3mdev device, nothing (flowi4_oif = 0 which
is the case in the example above) or a netdev index depending on the
lookup path. In each case, resetting orig_oif to the device in the fib
result for the RTN_LOCAL case allows the actual device to be preserved
as the skb tx and rx is done over the loopback or VRF device.

Currently, the function stmmac_mdio_register() is only used by
stmmac_dvr_probe() from stmmac_main.c, in order to register the MDIO bus
and probe information about the PHY. As this function is called before
calling register_netdev(), all messages logged from stmmac_mdio_register
are prefixed by "(unnamed net_device)". The goal of netdev_info or
netdev_err is to dump useful infos about a net_device, when this data
structure is partially initialized, there is no point for using these
functions.
This commit fixes the issue by replacing all netdev_*() by the
corresponding dev_*() function for logging. The last netdev_info is
replaced by phy_attached_info(), as a valid phydev can be used at this
point.

The patch c4adfc822b ("bonding: make speed, duplex setting consistent
with link state") puts the link state to down if
bond_update_speed_duplex() cannot retrieve speed and duplex settings.
Assumably the patch was written with 802.3ad mode in mind which relies
on link speed/duplex settings. For other modes like active-backup these
settings are not required. Thus, only for these other modes, this patch
reintroduces support for slaves that do not support reporting speed or
duplex such as wireless devices. This fixes the regression reported in
bug 196547 (https://bugzilla.kernel.org/show_bug.cgi?id=196547).

====================
netvsc: minor fixes and improvements
These are non-critical bug fixes, related to functionality now in net-next.
1. delaying the automatic bring up of VF device to allow udev to change name.
2. performance improvement
3. handle MAC address change with VF; mostly propogate the error that VF gives.
4. minor cleanups
5. allow setting send/receive buffer size with ethtool.
====================

Add ethtool statistics for case where send chimmeny buffer is
exhausted and driver has to fall back to doing scatter/gather
send. Also, add statistic for case where ring buffer is full and
receive completions are delayed.

Control the size of the buffer areas via ethtool ring settings.
They aren't really traditional hardware rings, but host API breaks
receive and send buffer into chunks. The final size of the chunks are
controlled by the host.
The default value of send and receive buffer area for host DMA
is much larger than it needs to be. Experimentation shows that
4M receive and 1M send is sufficient.

The function init_page_array is always called with a valid pointer
to RNDIS header. No check for NULL is needed.

Assignment to a typed pointer is sufficient in C.
No cast is needed.
