qeth_core_free_card() is meant to be the counterpart of
qeth_alloc_card() - but unfortunately was also picked as the place
to free the QDIO queues.
This gets messy when qeth_core_probe_device() fails during
qeth_add_dbf_entry(). At this point the card->qdio.state is not initialized
yet, so qeth_free_qdio_queues() ends up operating on uninitialized data.
Luckily for now, the whole qeth_card struct is zero-allocated and the value
of the QETH_QDIO_UNINITIALIZED enum is 0 as well. So there's no real impact
from this bug at the moment, it's just really fragile.
Clean this up by moving the qeth_free_qdio_queues() call up one level in
the hierarchy. This way it doesn't get called from the error path.

Packets with an unexpected HW format are currently first extracted from

finally dropped.
Enhance the RX path so that we can drop such packets before even
allocating an skb. For this, add some additional logic so that when a
packet is meant to be dropped, we can still walk along the packet's data
chunks in the RX buffer. This allows us to extract the following
packet(s) from the buffer.

Each RX buffer may contain up to 64KB worth of data. In case the device
needs to discard a packet _after_ already having reserved space for it
in the buffer, the whole buffer gets set to ERROR state. As the buffer
might contain any number of good packets, this can result in collateral
packet loss.
qeth can provide relief by enabling per-frame invalidation. The RX
buffer is then presented as usual, we just need to spot & drop any
individual packet that was flagged as invalid.

vsock: add multi-transports support
Most of the patches are reviewed by Dexuan, Stefan, and Jorgen.
The following patches need reviews:
- [11/15] vsock: add multi-transports support
- [12/15] vsock/vmci: register vmci_transport only when VMCI guest/host
are active
- [15/15] vhost/vsock: refuse CID assigned to the guest->host transport
RFC: https://patchwork.ozlabs.org/cover/1168442/
v1: https://patchwork.ozlabs.org/cover/1181986/
v1 -> v2:
- Patch 11:
+ vmci_transport: sent reset when vsock_assign_transport() fails
[Jorgen]
+ fixed loopback in the guests, checking if the remote_addr is the
same of transport_g2h->get_local_cid()
+ virtio_transport_common: updated space available while creating
the new child socket during a connection request
- Patch 12:
+ removed 'features' variable in vmci_transport_init() [Stefan]
+ added a flag to register only once the host [Jorgen]
- Added patch 15 to refuse CID assigned to the guest->host transport in
the vhost_transport
This series adds the multi-transports support to vsock, following
this proposal: https://www.spinics.net/lists/netdev/msg575792.html
With the multi-transports support, we can use VSOCK with nested VMs
(using also different hypervisors) loading both guest->host and
host->guest transports at the same time.
Before this series, vmci_transport supported this behavior but only
using VMware hypervisor on L0, L1, etc.
The first 9 patches are cleanups and preparations, maybe some of
these can go regardless of this series.
Patch 10 changes the hvs_remote_addr_init(). setting the
VMADDR_CID_HOST as remote CID instead of VMADDR_CID_ANY to make
the choice of transport to be used work properly.
Patch 11 adds multi-transports support.
Patch 12 changes a little bit the vmci_transport and the vmci driver
to register the vmci_transport only when there are active host/guest.
Patch 13 prevents the transport modules unloading while sockets are
assigned to them.
Patch 14 fixes an issue in the bind() logic discoverable only with
the new multi-transport support.
Patch 15 refuses CID assigned to the guest->host transport in the
vhost_transport.
I've tested this series with nested KVM (vsock-transport [L0,L1],
virtio-transport[L1,L2]) and with VMware (L0) + KVM (L1)
(vmci-transport [L0,L1], vhost-transport [L1], virtio-transport[L2]).

This patch adds the support of multiple transports in the
VSOCK core.
With the multi-transports support, we can use vsock with nested VMs
(using also different hypervisors) loading both guest->host and
host->guest transports at the same time.
Major changes:
- vsock core module can be loaded regardless of the transports
- vsock_core_init() and vsock_core_exit() are renamed to
vsock_core_register() and vsock_core_unregister()
- vsock_core_register() has a feature parameter (H2G, G2H, DGRAM)
to identify which directions the transport can handle and if it's
support DGRAM (only vmci)
- each stream socket is assigned to a transport when the remote CID
is set (during the connect() or when we receive a connection request
on a listener socket).
The remote CID is used to decide which transport to use:
- remote CID <= VMADDR_CID_HOST will use guest->host transport;
- remote CID == local_cid (guest->host transport) will use guest->host
transport for loopback (host->guest transports don't support loopback);
- remote CID > VMADDR_CID_HOST will use host->guest transport;
- listener sockets are not bound to any transports since no transport
operations are done on it. In this way we can create a listener
socket, also if the transports are not loaded or with VMADDR_CID_ANY
to listen on all transports.
- DGRAM sockets are handled as before, since only the vmci_transport
provides this feature.

Updated NPC KPU packet parsing profile with support for following
- Fragmentation support for IPv4 IPv6 outer header
- NIX instruction header support
- QinQ with TPID of 0x8100 as non inner most vlan tag, as legacy
network equipments still generate QinQ packets with this configuration.
- To better support RSS for tunnelled packets, udp based tunnel
protocols such as vxlan, vxlan-gpe, geneve and gtpu are now
captured into a separate layer E. Consequently, the inner
packet headers are pushed one layer down to LF, LG, and LH
accordingly.
- Support for rfc7510 mpls in udp. Up to 4 MPLS labels can be parsed
and captured in one layer LE.
- Parser support for DSA, extended DSA and eDSA tags right after
ethernet header by Marvell SOHO and Falcon switches. For extended
DSA and eDSA tags, a special PKIND of 62 is used, as these tags don't
contain a tpid field.
- Higig2 protocol header parsing support, added a NPC_LT_LA_HIGIG2_ETHER
for a combined header of HIGIG2 and Ethernet. Add a
NPC_LT_LA_IH_NIX_HIGIG2_ETHER for a combined header of nix_ih,
HIGIG2 and Ethernet on egress side. Also added 2 upper flags in LA to

- IPv4.TTL==0 IPv6.HLIM==0 check
- Per RFC 1858, mark fragment offset == 1 as error
- TCP invalid flags check
- Separate error codes for outer and inner IPv4 checksum errors.
- Fix a parser error when KPU parses incoming IPSec ESP and AH packets
- NPC vtag capture/strip hardware expect tag pointer to point to
