The RFE interrupt is enabled for the r8a7790 but isn't handled,
resulting in the interrupts core noticing unhandled interrupts, and
eventually disabling the ethernet IRQ.
Fix it by adding RFE to the bitmask of error interrupts to be handled
for r8a7790.

Jeff Kirsher says:
====================
This series contains updates to ixgbe and pci.
The first patch for ixgbe from Greg Rose is the second submission. The
first submission of "ixgbe: Retain VLAN filtering in promiscuous + VT
mode" had a typo, which Joe Perches pointed out and is fixed in this
submission.
Alex updates the ixgbe driver to use the generic helper pci_vfs_assigned
instead of the driver specific function ixgbe_vfs_are_assigned.
Don Skidmore provides 4 patches for ixgbe, the first being a fix for
flow control ethtool reporting. Originally ixgbe_device_supports_autoneg_fc()
was expected to be called by only copper devices, which lead to false
information being displayed via ethtool. Two other patches add support
for fixed fiber for SFP+ devices and the addition of a quad-port x520
adapter. The last patch simply bumps the driver version.
Emil Tantilov provides 3 fixes for ixgbe, two of which resolve
semaphore lock issues. The third fix resolves several issues in the
previous implementation of the SFF data dumps of SFP+ modules.
The remaining ixgbe and pci patches are from Jacob Keller. The pci
patches exposes bus speed, link speed and bus width so that drivers
can take advantage of this information. In addition, adds a pci function
which obtains minimum link width and speed. Jacob also provides the
ixgbe patch to incorporate the pci function. He provides a patch that
fixes a lockdep issue created due to ixgbe_ptp_stop always running
cancel_work_sync even if the work item had not been created properly with
INIT_WORK. This issue was found and reported by Stephen Hemminger.

Helgaas's feedback

This patch changes the error code path in ixgbe_acquire_swfw_sync() to deal
with cases where acquiring SW semaphore times out.
In cases where the SW/FW semaphore bits were set (i.e. due to a crash) the
driver will hang on load. With this patch the driver will clear
the stuck bits if the semaphore was not acquired in the allotted time.

This patch fixes a lockdep issue created due to ixgbe_ptp_stop always running
cancel_work_sync even if the work item had not been created properly with
INIT_WORK. This is caused because ixgbe_ptp_stop did not check to actually
ensure PTP was running first. The new implementation introduces a state in the
&adapter->state field which is used to indicate that PTP is running. (This
replaces the IXGBE_FLAG2_PTP_ENABLED field). This state will use the atomic
set_bit, test_bit, and test_and_clear_bit functions. ixgbe_ptp_stop will check
to ensure that PTP was enabled, (and if not, it will not attempt to do any
cleanup work from ixgbe_ptp_init). This resolves the lockdep annotation warning
found by Stephen Hemminger

This patch uses the new pcie_get_minimum_link function to perform a check to
ensure that the adapter is hooked into a slot which is capable of providing the
necessary bandwidth. This check supersedes the original method which only
checked the current pci device. The new method is capable of determining the
minimum speed and link of an entire PCI chain.

A PCI Express device can potentially report a link width and speed which it will
not properly fulfill due to being plugged into a slower link higher in the
chain. This function walks up the PCI bus chain and calculates the minimum link
width and speed of this entire chain. This can be useful to enable a device to
determine if it has enough bandwidth for optimum functionality.

This patch fixes several issues with the previous implementation of the
SFF data dump of SFP+ modules:
- removed the __IXGBE_READ_I2C flag - I2C access locking is handled in the
HW specific routines
- fixed the read loop to read data from ee->offset to ee->len
- the reads fail if __IXGBE_IN_SFP_INIT is set in the process - this is
needed because on some HW I2C operations can take long time and disrupt
the SFP and link detection process

ixgbe_read/write_i2c_phy_82598() does not hold the SWFW_SYNC
semaphore for the entire function. Instead the lock is held only
during the phy.ops.read/write_reg operations. As result when the
function is being called simultaneously the I2C read/writes can
be corrupted.
The following patch introduces the SWFW_SYNC semaphore for the
entire ixgbe_read/write_i2c_phy_82598() function. To accomplish
this I had to create 2 separate functions:
ixgbe_read_phy_reg_mdi()
ixgbe_write_phy_reg_mdi()
Those functions are identical to ixgbe_read/write_phy_reg_generic()
sans the locking, and can be used in ixgbe_read/write_i2c_phy_82598()
with the SWFW_SYNC semaphore being held.

Use the "swap descriptor" feature of the hardware to properly swap the
descriptors when running in big endian mode. Since the swapping occurs
on 64 bits words, we also need to provide a separate structure layout
for the DMA descriptors between little endian and big endian mode,
like is done in the mv643xx_eth driver.

The macros used for the various fields of the RX and TX descriptions
are currently declared next to those fields within the structure
definitions of the RX and TX descriptors.
However, in order to support big endian, we'll have to use the "swap
descriptors" features of the hardware, which swaps every byte within
each 64 bits word of the descriptors. This requires a separate
definition of the RX and TX descriptor structures for little and big
endian, as is done in the mv643xx_eth. Those macros can therefore no
longer be defined inside those structures.

Previously, when the interface was brought down, the driver would set
the power state to D3hot. In D3hot, we don't have access to the NVRAM.
This patch removes the call to set the power state to PCI_D3hot in
close. A following patch will implement the shutdown handler to properly
set the D3hot state when the system is going down.
Doing the above means that the TG3_PHYFLG_IS_LOW_POWER should not be

During probe, the driver is incorrectly switching the power to Vaux on
the 5717 and later devices. At this point, we are in D0 state and
drawing maximum power. We also definitely have Vmain available. It
doesn't make sense to switch to Vaux since it has a lesser maximum power
draw and we might go over the limit. On a new system, we observe that
not all ports are recognized in some of the slots with this call in
place.

This commit adds new firmware command and new firmware event. The firmware
raises the MLX4_EVENT_TYPE_OP_REQUIRED event in order to signal the driver it
needs to perform an administrative operation throughout the MLX4_CMD_GET_OP_REQ

Fix a race between BlueFlame flow and stamping in post send flow.
Example:
SW: Build WQE 0 on the TX buffer, except the ownership bit
SW: Set ownership for WQE 0 on the TX buffer
SW: Ring doorbell for WQE 0
SW: Build WQE 1 on the TX buffer, except the ownership bit
SW: Set ownership for WQE 1 on the TX buffer
HW: Read WQE 0 and then WQE 1, before doorbell was rung/BF was done for WQE 1
HW: Produce CQEs for WQE 0 and WQE 1
SW: Process the CQEs, and stamp WQE 0 and WQE 1 accordingly (on the TX buffer)
SW: Copy WQE 1 from the TX buffer to the BF register - ALREADY STAMPED!
HW: CQE error with index 0xFFFF - the BF WQE's control segment is STAMPED,
so the BF index is 0xFFFF. Error: Invalid Opcode.
As a result QP enters the error state and no traffic can be sent.
Solution:
When stamping - do not stamp last completed wqe.
