Fix the min_t calls in the zeroing and dirtying helpers to perform the

When we try to allocate a free inode by searching the inobt, we try to
find the inode nearest the parent inode by searching chunks both left
and right of the chunk containing the parent. As an optimization, we
cache the leftmost and rightmost records that we previously searched; if
we do another allocation with the same parent inode, we'll pick up the
search where it last left off.
There's a bug in the case where we found a free inode to the left of the
parent's chunk: we need to update the cached left and right records, but
because we already reassigned the right record to point to the left, we
end up assigning the left record to both the cached left and right
records.
This isn't a correctness problem strictly, but it can result in the next
allocation rechecking chunks unnecessarily or allocating inodes further
away from the parent than it needs to. Fix it by swapping the record
pointer after we update the cached left and right records.

When CONFIG_NET_SCHED or CONFIG_NET_RX_BUSY_POLL is /not/ set and
we try a narrow __sk_buff load of tc_index or napi_id, respectively,
then verifier rightfully complains that it's misconfigured, because
we need to set target_size in each of the two cases. The rewrite
for the ctx access is just a dummy op, but needs to pass, so fix
this up.

The Flower app may receive a request to update the MTU of a representor
netdev upon receipt of a control message from the firmware. This requires
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

valid_lft forever preferred_lft forever
inet6 fe80::e0:f9ff:fe1c:37/64 scope link
valid_lft forever preferred_lft forever
$ 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 c4adfc822bf5 ("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).

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 send and receive buffers are both per-device (not per-channel).
The associated NUMA node is a property of the CPU which is per-channel
therefore it makes no sense to force the receive/send buffer to be
allocated on a particular node (since it is a shared resource).

If setting new values fails, and the attempt to restore original
settings fails. Then log an error and leave device down.
This should never happen, but if it does don't go down in flames.

If VF is slaved to synthetic device, then any change to netvsc
MAC address should be propagated to the slave device.
If slave device doesn't support MAC address change then it
should also be an error to attempt to change synthetic NIC MAC
address.
It also fixes the error unwind in the original code.
If give a bad address, the old code would change the device
MAC address anyway.
