1) Fix a name of the error bit to correctly indicate the error.
2) Added a fd_id field in the 32 byte desc at the place(qw0) where it gets
reported in the programming error desc WB. In a normal data desc
the fd_id field is reported in qw3.

The update filter logic was causing a kernel panic in the original code.
We need to compare the input set to decide whether or not to delete a
filter since we do not have a hash stored. This new design helps fix the issue.

We've been deleting the netdev before getting around to deleting the napi
structs. Unfortunately, we then didn't delete the napi structs because we
have a check for netdev, thus we were leaving garbage around in the system.

If the sh_eth device is registered using OF, then the driver
should call of_mdiobus_register() to register the PHYs described
in the devicetree and then use of_phy_connect() to connect the
PHYs to the device.
This ensures that any PHYs registered in the device tree are
appropriately connected to the parent devices nodes so that
the PHY drivers can access their OF properties.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates
This series contains updates to igb, e1000e, ixgbe and ixgbevf.
Tom Herbert provides changes to e1000e, igb and ixgbe to call skb_set_hash()
to set the hash and its type in an skbuff.
Carolyn provides a fix for igb where using ethtool for EEE settings, which
was not working correctly.
Jacob provides some trivial cleanups and fixes for ixgbe which mainly
dealt with the file headers.
Julia Lawall provides a one fix for ixgbevf where the driver did not need
to adjust the power state on suspend, so the call to pci_set_power_state()
in the resume function was a no-op.
v2:
- dropped patches 4-6 from original series which implemented debugfs for
igb from Carolyn based on feed back from David Miller and Or Gerlitz

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.

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.

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.

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).

This requires the following modifications:
1. Fix build_mlx4_header to properly fill in the ETH fields
2. Adjust mux and demux QP1 flow to support RoCE.
This commit still assumes only one GID per slave for RoCE.
The commit enabling multiple GIDs is a subsequent commit, and
is done separately because of its complexity.

priv is not instantiated at gfar_of_init() time, when
parsing the DT for info on supported HW queues. Before
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.
