Since there is no connection between the MAC/VLAN and the GID
when using IP-based addressing, the proxy QP1 (running on the
slave) must pass the source-mac, destination-mac, and vlan_id
information separately from the GID. Additionally, the Host
must pass the remote source-mac and vlan_id back to the slave,
This is achieved as follows:
Outgoing MADs:
1. Source MAC: obtained from the CQ completion structure
(struct ib_wc, smac field).
2. Destination MAC: obtained from the tunnel header
3. vlan_id: obtained from the tunnel header.
Incoming MADs
1. The source (i.e., remote) MAC and vlan_id are passed in
the tunnel header to the proxy QP1.
VST mode support:
For outgoing MADs, the vlan_id obtained from the header is
discarded, and the vlan_id specified by the Hypervisor is used
instead.
For incoming MADs, the incoming vlan_id (in the wc) is discarded, and the
"invalid" vlan (0xffff) is substituted when forwarding to the slave.

The IB side of RoCE requires the MAC table index of the
MAC address used by its QPs.
To obtain the real MAC index, the IB side registers the
MAC (increasing its ref count, and also returning the
real MAC index) during the modify-qp sequence.
This protects against the ETH side deleting or modifying
that MAC table entry while the QP is active.
Note that until the modify-qp command returns success,
the MAC and VLAN information only has "candidate" status.
If the modify-qp succeeds, the "candidate" info is promoted
to the operational MAC/VLAN info for the qp. If the modify fails,
the candidate MAC/VLAN is unregistered, and the old qp info
is preserved.
The patch is a bit complex, because there are multiple qp
transitions where the primary-path information may be
modified: INIT-to-RTR, and SQD-to-SQD.
Similarly for the alternate path information.
Therefore the code must handle cases where path information
has already been entered into the QP context by previous
qp transitions.
For the MAC address, the success logic is as follows:
1. If there was no previous MAC, simply move the candidate
MAC information to the operational information, and reset
the candidate MAC info.
2. If there was a previous MAC, unregister it. Then move
the MAC information from candidate to operational, and
reset the candidate info (as in 1. above).
The MAC address failure logic is the same for all cases:
- Unregister the candidate MAC, and reset the candidate MAC info.
For Vlan registration, the logic is similar.

For IB transport, the host determines the slave GIDs. For ETH (RoCE),
however, the slave's GID is determined by the IP address that the slave

In this case, the slave must be able to write its GIDs to the HCA gid table
(at the GID indices that slave "owns").

tipc: simplifications in socket and port layer
After the removal of the tipc native API the relation between
tipc_port and its API types is strictly one-to-one, i.e, the latter
can now only be a socket API. This change opens up for
simplifications both in the code, data and locking structure.
We start with this series, where we ensure that port and socket
structures are co-allocated. Note that the first commit in the
series is unrelated to the above.

Signed-off-by: David S. Miller <davem@davemloft.net>
As an artefact from the native interface, the message sending functions
in the port takes a port ref as first parameter, and then looks up in
the registry to find the corresponding port pointer. This despite the
fact that the only currently existing caller, tipc_sock, already knows
this pointer.
We change the signature of these functions to take a struct tipc_port*
argument, and remove the redundant lookups.
We also remove an unmotivated extra lookup in the function
socket.c:auto_connect(), and, as the lookup functions tipc_port_deref()
and ref_deref() now become unused, we remove these two functions.

Due to the original one-to-many relation between port and user API
layers, upcalls to the API have been performed via function pointers,
installed in struct tipc_port at creation. Since this relation now
always is one-to-one, we can instead use ordinary function calls.
We remove the function pointers 'dispatcher' and ´wakeup' from
struct tipc_port, and replace them with calls to the renamed
functions tipc_sk_rcv() and tipc_sk_wakeup().
At the same time we change the name and signature of the functions
tipc_createport() and tipc_deleteport() to reflect their new role
as mere initialization/destruction functions.

Paul reported that after f75b99d5a7 ("PCI: Enforce bus address limits in

set), intel-gtt complained "can't ioremap flush page - no chipset
flushing". In addition, other PCI resource allocations, e.g., for bridge
windows, failed.
This happens because we incorrectly skip bus resources of
[mem 0x00000000-0xffffffff] because we think they are of size zero.
When resource_size_t is 32 bits wide, resource_size() on
[mem 0x00000000-0xffffffff] returns 0 because (r->end - r->start + 1)
overflows.
Therefore, we can't use "resource_size() == 0" to decide that allocation
from this resource will fail. allocate_resource() should fail anyway if it
can't satisfy the address constraints, so we should just depend on that.
A [mem 0x00000000-0xffffffff] bus resource is obviously not really valid,
but we do fall back to it as a default when we don't have information about
host bridge apertures.
