Fix potential null-pointer dereference at probe if the mdio-gpio device
has not been successfully probed yet.
The offending commit is plain wrong for a number of reasons. First of
all it accesses internal driver data of an unrelated device. Neither
does it check that the data is non-null (which it is in case the device
has not been probed yet).
Furthermore, the decision on whether to treat any driver data according
to the mdio-gpio driver's internals is made based on the node name. But
the name is not compared against "mdio" which is the normal name for the
node, but rather against "gpio" which the node does not have to be named
(and shouldn't be according to the binding documentation). [ If this
hack is to be kept out-of-tree it should at least be matching against
the compatible property. ]

This driver maps 802.1q VLANs to MBIM sessions. The mapping is based on
a bogus assumption that all tagged frames will use the acceleration API
because we enable NETIF_F_HW_VLAN_CTAG_TX. This fails for e.g. frames
tagged in userspace using packet sockets. Such frames will erroneously
be considered as untagged and silently dropped based on not being IP.
Fix by falling back to looking into the ethernet header for a tag if no
accelerated tag was found.

qlcnic: Fix Kconfig dependency on HWMON
Commit 1f0f467b670e "qlcnic: Add hwmon interface to export board
temperature" introduced a randconfig build error in the case
when the hwmon framework is built as a module and the qlcnic
driver itself is built-in:
drivers/built-in.o: In function `qlcnic_register_hwmon_dev':
drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1301:
undefined reference to `hwmon_device_register_with_groups'
drivers/built-in.o: In function `qlcnic_unregister_hwmon_dev':
drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1309:
undefined reference to `hwmon_device_unregister'.
This changes the Kconfig logic to enforce that the qlcnic hwmon
support can only be enabled if it is possible to successfully
build it.

net: clean up snmp stats code
commit 8f0ea0fe3a036a47767f9c80e (snmp: reduce percpu needs by 50%)
reduced snmp array size to 1, so technically it doesn't have to be
an array any more. What's more, after the following commit:
We simply say that regular this_cpu use must be safe regardless of
preemption and interrupt state. That has no material change for x86
and s390 implementations of this_cpu operations. However, arches that
do not provide their own implementation for this_cpu operations will
now get code generated that disables interrupts instead of preemption.
probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after
almost 3 years, no one complains.
So, just convert the array to a single pointer and remove snmp_mib_init()
and snmp_mib_free() as well.

net: ip: push gso skb forwarding handling down the stack
Turns out doing the segmentation in forwarding was not a bright idea,
there are corner-cases where this has unintended side-effects.
This patch pushes the segmentation downwards.
After this, netif_skb_dev_features() function can be removed
again, it was only added to fetch the features of the output device,
we can just use skb->dev after the pushdown.
Tested with following setup:
host -> kvm_router -> kvm_host
mtu 1500 mtu1280
- 'host' has route to kvm_host with locked mtu of 1500
- gso/gro enabled on all interfaces
Did tests with all of following combinations:
- netfilter conntrack off and on on kvm_router
- virtio-net and e1000 driver on kvm_router
- tcp and udp bulk xmit from host to kvm_host
for tcp, I added TCPMSS mangling on kvm_host to make it lie about tcp mss.
Also added a dummy '-t mangle -A POSTROUTING -p udp -f'
rule to make sure no udp fragments are seen in the 'conntrack on'
and 'virtio-net' case.
Also checked (with ping -M do -s 1400)' that it still sends the wanted
icmp error message when size exceeds 1280.

net: ip: push gso skb forwarding handling down the stack
Doing the segmentation in the forward path has one major drawback:
When using virtio, we may process gso udp packets coming
from host network stack. In that case, netfilter POSTROUTING
will see one packet with udp header followed by multiple ip
fragments.
Delay the segmentation and do it after POSTROUTING invocation
to avoid this.

local_df means 'ignore DF bit if set', so if its set we're
allowed to perform ip fragmentation.
This wasn't noticed earlier because the output path also drops such skbs
(and emits needed icmp error) and because netfilter ip defrag did not
set local_df until couple of days ago.
Only difference is that DF-packets-larger-than MTU now discarded
earlier (f.e. we avoid pointless netfilter postrouting trip).
While at it, drop the repeated test ip_exceeds_mtu, checking it once
is enough...
