c1d81b1cf9 VFS: Fix up some ->d_inode accesses in the chelsio driver
Fix up some ->d_inode accesses in the chelsio driver.

 (1) FILE_DATA() should just be replaced with file_inode().

 (2) set_debugfs_file_size() should be removed and debugfs_create_file_size()
     should be used to create the file.

All places outside of core VFS that checked ->read and ->write for being NULL or
called the methods directly are gone now, so NULL {read,write} with non-NULL
{read,write}_iter will do the right thing in all cases.

Conflicts:

	net/core/fib_rules.c
	net/ipv4/fib_frontend.c

The fib_rules.c and fib_frontend.c conflicts were locking adjustments
in 'net' overlapping addition and removal of code in 'net-next'.

The mlx4 conflict was a bug fix in 'net' happening in the same
place a constant was being replaced with a more suitable macro.

898b2970e2 mvneta: implement SGMII-based in-band link state signaling
When MDIO bus is unavailable (common setup for SGMII), the in-band
signaling must be used to correctly track link state.
This patch enables the in-band status delivery for link state changes, namely:
- link up/down
- link speed
- duplex full/half
fixed_phy_update_state() is used to update phy status.

a3bebdce41 add fixed_phy_update_state() - update state of fixed_phy
Currently fixed_phy uses a callback to periodically poll the link state.
This patch adds the fixed_phy_update_state() API.
It solves the following problems:
- On link state interrupt, MAC driver can't update status.
Instead it needs to provide the callback to periodically query
the HW about the link state. It is more efficient to update status
after interrupt.
- The callback needs to be unregistered before phy_disconnect(),
or otherwise it will be called with net_dev==NULL. phy_disconnect()
does not have enough info to unregister the callback automatically.
- The callback needs to be registered before of_phy_connect() to
avoid running with outdated state, but of_phy_connect() returns the
phy_device pointer, which is needed to register the callback. Registering
it before of_phy_connect() will therefore require a hack to get the
pointer earlier.

Overall, this addition makes the subsequent patch that implements
SGMII link status for mvneta, much cleaner.

fdf0e0bfc3 i40e: Communicate VSI id in place of VSI index to the VFs
This does not affect the Virtual channel API as such but it changes the
meaning of what is communicated to the VSI resource struct as vsi_id.
Earlier vsi_idx was being passed in, which was the index in the PF's VSI
array. Now we pass vsi_id as communicated by the FW to the driver.
This will help with future expansion of VF and FW communication.

With this in place now the VF and Virtual channel driver change to move over
to VSI id use is complete and is validated.

08068cd568 net/mlx4: Added qos_vport QP configuration in VST mode
Granular QoS per VF feature introduce a new QP field, qos_vport.

PF administrator can connect VF QPs to a certain QoS Vport, to
inherit its proporties. Connecting QPs to the default QoS Vport
(defined as 0) is always allowed, even when there are no allocated VPPs.
At this point, only the default vport is connected to QPs.

666672d480 net/mlx4: Allocate VPPs for each port on PF init
Initialization of granular Qos per VF mechanism.

Query the port availible VPPs and allocates those on all supported
priorities in an equal share. Allocation is done only in SRIOV mode,
when the feature is supported by the device and port type is Ethernet.

Allocation currently is done only on the default priority 0.

1c29146d38 net/mlx4: Add mlx4_SET_VPORT_QOS implementation
Add the SET_VPORT_QOS device command, which is ntended for virtual
granular QoS configuration per VF in SRIOV mode. The SET_VPORT_QOS
command sets and queries QoS parameters of a VPort. Each priority
allowed for a VPort is assigned with a share of the BW, and a BW
limitation. QoS parameters can be modified at any time, but must be
initialized before any QP is associated with the VPort.

7e95bb99a8 net/mlx4: Add mlx4_ALLOCATE_VPP implementation
Implements device ALLOCATE_VPP command, to be used for granular QoS
configuration of VFs by the PF device. Defines and queries the amount
of VPPs assigned to each port, and the amount of VPPs assigned to each
priority of each port. Once the total VPPs are split between the priorities
of a port, they may be assigned with a share of the BW or a rate limit.

Split into two functions (get/set) whoch are supplied with
mlx4_alloc_vpp_context and physical port number.

12a889c057 net/mlx4: New file for QoS related firmware commands
Create two new files fw_qos.h and fw_qos.c in mlx4_core module.

It gathers all relevant QoS firmware related commands etc, thus improving
encapsulation of the mlx4_core module. For now it contains the QoS existing
commands: mlx4_SET_PORT_SCHEDULER and mlx4_SET_PORT_PRIO2TC.
