When VBUS is not discovered within PD_T_PS_SOURCE_ON although Rp
is detected on CC, TCPM switches the port to SNK_UNATTACHED
state. SNK_UNATTACHED, however does not force TYPEC_CC_OPEN which
makes the partner(source) to think that it is connected.
To overcome this issue, force the port into PORT_RESET state
to make sure the CC lines are open.

PING messages are used to monitor the connect/disconnect.
However, when PD is carried over CC, so this is not required.
Also, the spec does not clearly say if PD is possible when
Type-c is connected to Type-A/B. So, removing sending
PING messages altogether.

Once, Rp or Rd is switched, wait for PD_T_CC_DEBOUNCE. If not the
PS_RDY message transmitted might result in failure.
Also, Only wait for PD_T_SRCSWAPSTDBY while in
PR_SWAP_SRC_SNK_TRANSITION_OFF. PD_T_PS_SOURCE_OFF is the overall
time after which the initial sink would issue hard reset.

In the case that the lower layer driver reports a cc change directly
from SINK state to SOURCE state, TCPM doesn't handle these cc change
in SRC_SEND_CAPABILITIES, SRC_READY states. And with SRC_ATTACHED
state, the change is not handled as the port is still considered
connected.

While performing PORT_RESET, upon receiving the cc disconnect
signal from the underlaying tcpc device, TCPM transitions into

This IOCTL provides a mechanism for userspace to trigger a sync object
directly. There are other ways that userspace can trigger a syncobj
such as submitting a dummy batch somewhere or hanging on to a triggered
sync_file and doing an import. This just provides an easy way to
manually trigger the sync object without weird hacks.
The motivation for this IOCTL is Vulkan fences. Vulkan lets you create
a fence already in the signaled state so that you can wait on it
immediatly without stalling. We could also handle this with a new
create flag to ask the driver to create a syncobj that is already
signaled but the IOCTL seemed a bit cleaner and more generic.

If we cannot allocate RX buffers in the NAPI poll loop when processing

When the number of TX rings is changed (e.g. ethtool -L, enabling XDP TX
rings, etc), the current code tries to reserve the new number of TX rings
before closing and re-opening the NIC. If we are unable to reserve the
new TX rings, we abort the operation and keep the current TX rings.
The problem is that the firmware will disable the current TX rings even
when it cannot reserve the new set of TX rings. We fix it as follows:
1. Instead of reserving the new set of TX rings, just ask the firmware
to check if the new set of TX rings is available. There is a flag in
the firmware message to do that. If not available, abort and the
current TX rings will not be disabled.
2. Do the actual TX ring reservation in the path that opens the NIC.
We keep the number of TX rings currently successfully reserved. If the
number of TX rings is different than the reserved TX rings, we call
firmware and reserve again.

NCSI VLAN Filtering Support
This series (mainly patch 2) adds VLAN filtering to the NCSI implementation.
A fair amount of code already exists in the NCSI stack for VLAN filtering but
none of it is actually hooked up. This goes the final mile and fixes a few
bugs in the existing code found along the way (patch 1).
Patch 3 adds the appropriate flag and callbacks to the ftgmac100 driver to
enable filtering as it's a large consumer of NCSI (and what I've been
testing on).

Make use of the ndo_vlan_rx_{add,kill}_vid callbacks to have the NCSI
stack process new VLAN tags and configure the channel VLAN filter
appropriately.
Several VLAN tags can be set and a "Set VLAN Filter" packet must be sent
for each one, meaning the ncsi_dev_state_config_svf state must be
repeated. An internal list of VLAN tags is maintained, and compared
against the current channel's ncsi_channel_filter in order to keep track
within the state. VLAN filters are removed in a similar manner, with the
introduction of the ncsi_dev_state_config_clear_vids state. The maximum
number of VLAN tag filters is determined by the "Get Capabilities"
response from the channel.

====================
40GbE Intel Wired LAN Driver Updates 2017-08-27
This series contains updates to i40e and i40evf only.
Sudheer updates code comments and state variable so that adminq_subtask
will have accutate information whenever it gets scheduled.
Mariusz stores information about FEC modes, to be used to printing link
states information, so that we do not need to call admin queue when
reporting link status. Adds VF support for controlling VLAN tag
stripping via ethtool.
Jake provides the majority of changes in this series, starting with
increasing the size of the prefix buffer so that it can hold enough
characters for every possible input, which prevents snprintf truncation.
Fixed other string truncation errors/warnings produced by GCC 7.x.
Removed an unnecessary workaround for resetting XPS. Fixed an issue
where there is a mismatched affinity mask value, so initialize the value
to cpu_possible_mask and invert the logic for checking incorrect CPU vs
IRQ affinity so that the exceptional case is handled at the check.
Removed ULTRA latency mode due to several issues found and will be
looking at better solution for small packet workloads.
Akeem fixes an issue where the incorrect flag was being used to set
promiscuous mode for unicast, which was enabling promiscuous mode only
for multicast instead of unicast.
Carolyn fixes an issue where an error return value is set, but this
value can be overwritten before we actually do exit the function. So
remove the error code assignment and add code comments for better
understanding on why we do not need to set and return the error.

Commit 3510ca20ece0 ("Minor page waitqueue cleanups") made the page
queue code always add new waiters to the back of the queue, which helps
upcoming patches to batch the wakeups for some horrid loads where the
wait queues grow to thousands of entries.
However, I forgot about the nasrt add_page_wait_queue() special case
code that is only used by the cachefiles code. That one still continued
to add the new wait queue entries at the beginning of the list.
Fix it, because any sane batched wakeup will require that we don't
suddenly start getting new entries at the beginning of the list that we
already handled in a previous batch.
[ The current code always does the whole list while holding the lock, so
wait queue ordering doesn't matter for correctness, but even then it's
better to add later entries at the end from a fairness standpoint ]

irda: move it to drivers/staging so we can delete it
The IRDA code has long been obsolete and broken. So, to keep people
from trying to use it, and to prevent people from having to maintain it,
let's move it to drivers/staging/ so that we can delete it entirely from
the kernel in a few releases.

The irda code will be deleted in a future kernel release, so no need to
have anyone do any new work on it.

And finally, move the irda include files into
drivers/staging/irda/include/net/irda. Yes, it's a long path, but it
makes it easy for us to just add a Makefile directory path addition and
all of the net and drivers code "just works".

It's time to get rid of IRDA. It's long been broken, and no one seems
to use it anymore. So move it to staging and after a while, we can
delete it from there.
To start, move the network irda core from net/irda to
drivers/staging/irda/net/
