b5a637881f ath6kl: update Kconfig descriptions
The help text were either out of date, too small or didn't exist at all. Also
move cfg80211 dependency to ath6kl_core module as it has all the calls to
cfg80211.

Fixes checkpatch warning:

Jason noticed that with Yocto GCC 4.8.1 ath6kl crashes with this iperf command:

Kernel panic - not syncing: Fatal exception

Jason's analysis:

  "The GCC 4.8.1 compiler will not do the for-loop till scat_entries, instead,
   it only run one round loop. This may be caused by that the GCC 4.8.1 thought
   that the scat_list only have one item and then no need to do full iteration,
   but this is simply wrong by looking at the assebly code. This will cause the sg
   buffer not get set when scat_entries > 1 and thus lead to kernel panic.

   Note: This issue not observed with GCC 4.7.2, only found on the GCC 4.8.1)"

Fix this by using the normal [0] style for defining unknown number of list
entries following the struct. This also fixes corruption with scat_q_depth, which
was mistankely added to the end of struct and overwritten if there were more
than item in the scat list.

aa9a2d51a3 mlx4: Activate RoCE/SRIOV
To activate RoCE/SRIOV, need to remove the following:
1. In mlx4_ib_add, need to remove the error return preventing
   initialization of a RoCE port under SRIOV.
2. In update_vport_qp_params (in resource_tracker.c) need to remove
   the error return when a RoCE RC or UD qp is detected.
   This error return causes the INIT-to-RTR qp transition to fail
   in the wrapper function under RoCE/SRIOV.

5ea8bbfc49 mlx4: Implement IP based gids support for RoCE/SRIOV
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.

2f5bb47368 mlx4: Add ref counting to port MAC table for RoCE
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.

The GIDs are statically distributed, as follows:
PF: gets 16 GIDs
VFs:  Remaining GIDS are divided evenly between VFs activated by the driver.
      If the division is not even, lower-numbered VFs get an extra GID.

For an IB interface, the number of gids per guest remains as before: one gid per guest.

9cd593529c mlx4_core: For RoCE, allow slaves to set the GID entry at that slave's index
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
itself assigns to the ETH device used by RoCE.

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

This commit adds processing for the SET_PORT_GID_TABLE opcode modifier
for the SET_PORT command wrapper (so that slaves may modify their GIDS
for RoCE).

the netdev can be allocated, the number of supported
queues must be known.  Because the number of supported
queues depends on device type, move the compatibility
checks before netdev allocation.  Local vars are used
to hold the operation mode info before netdev allocation.
This fixes the null accesses for priv->.., in gfar_of_init.
