net: bcmgenet: Software reset EPHY after power on
The EPHY on GENET v1->v3 is extremely finicky, and will show occasional
failures based on the timing and reset sequence, ranging from duplicate
packets, to extremely high latencies.
Perform an additional software reset, and re-configuration to make sure it is
in a consistent and working state.

VSOCK: define VSOCK_SS_LISTEN once only
The SS_LISTEN socket state is defined by both af_vsock.c and
vmci_transport.c. This is risky since the value could be changed in one
file and the other would be out of sync.
Rename from SS_LISTEN to VSOCK_SS_LISTEN since the constant is not part
of enum socket_state (SS_CONNECTED, ...). This way it is clear that the
constant is vsock-specific.
The big text reflow in af_vsock.c was necessary to keep to the maximum
line length. Text is unchanged except for s/SS_LISTEN/VSOCK_SS_LISTEN/.

net: smsc911x: Fix crash if loopback test fails
On certain hardware in certain situations loopback test fails and the
driver gets removed. During mdiobus_unregister() instance of PHY driver
gets disposed. But by this time it has already been started using
phy_connect_direct().
PHY driver uses DELAYED_WORK in order to maintain its state. Attempting
to dispose the driver without calling phy_disconnect() causes deallocation
of DELAYED_WORK being active. This shortly causes a bad crash in timer
code.
The problem can be discovered by enabling CONFIG_DEBUG_OBJECTS_TIMERS and
CONFIG_DEBUG_OBJECTS_FREE

tipc: linearize arriving NAME_DISTR and LINK_PROTO buffers
Testing of the new UDP bearer has revealed that reception of
NAME_DISTRIBUTOR, LINK_PROTOCOL/RESET and LINK_PROTOCOL/ACTIVATE
message buffers is not prepared for the case that those may be
non-linear.
We now linearize all such buffers before they are delivered up to the
generic reception layer.
In order for the commit to apply cleanly to 'net' and 'stable', we do
the change in the function tipc_udp_recv() for now. Later, we will post
a commit to 'net-next' moving the linearization to generic code, in
tipc_named_rcv() and tipc_link_proto_rcv().

net: clean up interactions of CHECKSUM_PARTIAL and fragmentation
This series fixes wrong checksums on the wire for IPv4 and IPv6. Large
send buffers and especially NFS lead to wrong checksums in both IPv4
and IPv6.
CHECKSUM_PARTIAL skbs should not receive the respective fragmentations
functions, so we add WARN_ON_ONCE to those functions to fix up those as
soon as they get reported.
Changelog:
v2: added v4 checks
v3: removed WARN_ON_ONCES (advice by Tom Herbert)

ipv6: no CHECKSUM_PARTIAL on MSG_MORE corked sockets
We cannot reliable calculate packet size on MSG_MORE corked sockets
and thus cannot decide if they are going to be fragmented later on,
so better not use CHECKSUM_PARTIAL in the first place.
The IPv6 code also intended to protect and not use CHECKSUM_PARTIAL in
the existence of IPv6 extension headers, but the condition was wrong. Fix
it up, too. Also the condition to check whether the packet fits into
one fragment was wrong and has been corrected.
