40GbE Intel Wired LAN Driver Updates 2017-02-11
This series contains updates to i40e and i40evf only.
Jake makes a minor change to prevent a minor bit of work, if it is not
necessary. In the case where we do not have a client, there is no need
to check the client params, so move the check till after we have ensured
we have a client. Correct a code comment which incorrectly implied
that raw_packet buffers were freed in i40e_clean_tx_ring(), so fixed
the code comment to better explain where memory is freed. Reduce the
severity and frequency of the message notifying we cleared the receive
timestamp register, since the logic has a much better detection scheme
that could detect a stalled receive timestamp register. The improved
logic was actually causing the notification message to occur more
frequently and was giving the user a false perception that a timestamp
event was missed for a valid packet, so reduce the severity from
dev_warn to dev_dbg and only fire off the message when 3 or 4 of the
RXTIME registers are stalled and get cleared within the same
watchdog event. Fixed a bug, where we were modifying the mac_filter
outside a lock when handling the addition of broadcast filters. Fix
this by updating i40e_update_filter_state logic so that it knows to
avoid broadcast filters, which ensures that we do not have to remove
the filter separately and can put it back using the normal flow.
Refactored how we add new filters to firmware to avoid a race condition
that can occur due to removing filters from the hash temporarily.
Mitch adds a sleep (without timeout) so that we wait for a reply from
the PF before we continue, since the iWarp client cannot continue until
the operation is completed. Fixed up a function which could never
return an error, to be void and cleaned up the checking of the now
null and void return value.
Scott limits the DMA sync to CPU to the actual length of the incoming
packet, versus the syncing of the entire buffer. Also reduces the
receive buffer struct (by a single pointer) and align the driver to be
more consistent with other Intel drivers with respect to packets that
span buffers.
Sudheer adds a field to track the bus number info and modified log
statements to print bus, device and function information.
Henry adds the ability to store the FEC status bits from the link up
event. Also adds the ethtool support for FEC capabilities and 25G
link types.

rhashtable: Handle table allocation failure during insertion
v2 -
Added Ack to patch 2.
Fixed RCU annotation in code path executed by rehasher by using
rht_dereference_bucket.
v1 -
This series tackles the problem of table allocation failures during
insertion. The issue is that we cannot vmalloc during insertion.
This series deals with this by introducing nested tables.
The first two patches removes manual hash table walks which cannot
work on a nested table.
The final patch introduces nested tables.
I've tested this with test_rhashtable and it appears to work.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This patch adds code that handles GFP_ATOMIC kmalloc failure on
insertion. As we cannot use vmalloc, we solve it by making our
hash table nested. That is, we allocate single pages at each level
and reach our desired table size by nesting them.
When a nested table is created, only a single page is allocated
at the top-level. Lower levels are allocated on demand during
insertion. Therefore for each insertion to succeed, only two
(non-consecutive) pages are needed.
After a nested table is created, a rehash will be scheduled in
order to switch to a vmalloced table as soon as possible. Also,
the rehash code will never rehash into a nested table. If we
detect a nested table during a rehash, the rehash will be aborted
and a new rehash will be scheduled.

There are two problems with the function tipc_sk_reinit. Firstly
it's doing a manual walk over an rhashtable. This is broken as
an rhashtable can be resized and if you manually walk over it
during a resize then you may miss entries.
Secondly it's missing memory barriers as previously the code used
spinlocks which provide the barriers implicitly.
This patch fixes both problems.

When sending ARP requests over AX.25 links the hwaddress in the neighbour
cache are not getting initialized. For such an incomplete arp entry
ax2asc2 will generate an empty string resulting in /proc/net/arp output
like the following:
$ cat /proc/net/arp
IP address HW type Flags HW address Mask Device
192.168.122.1 0x1 0x2 52:54:00:00:5d:5f * ens3
172.20.1.99 0x3 0x0 * bpq0
The missing field will confuse the procfs parsing of arp(8) resulting in
incorrect output for the device such as the following:
$ arp
Address HWtype HWaddress Flags Mask Iface
gateway ether 52:54:00:00:5d:5f C ens3
172.20.1.99 (incomplete) ens3
This changes the content of /proc/net/arp to:
$ cat /proc/net/arp
IP address HW type Flags HW address Mask Device
172.20.1.99 0x3 0x0 * * bpq0
192.168.122.1 0x1 0x2 52:54:00:00:5d:5f * ens3
To do so it change ax2asc to put the string "*" in buf for a NULL address
argument. Finally the HW address field is left aligned in a 17 character
field (the length of an ethernet HW address in the usual hex notation) for
readability.

The problem is that many drivers can convert R'G'B' content (often
from sensors) to Y'CbCr, but they all produce limited range Y'CbCr.
To stay backwards compatible the default quantization range for
sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full
range, even though the corresponding standards specify full range.
Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and
also update the documentation.

mv88e6xxx Watchdog support
The Marvell switches have an in built watchdog over some of the
internal state machine. The watchdog can be configured to raise an
interrupt on error. The problem the watchdog found is then logged to
the kernel log.
The older switches can automagically perform a software reset when the
watchdog triggers. This just resets the internal state machine, but
leaves the switch configuration unchanged.
The 6390 family of switches cannot both raise an interrupt and
automagically perform a software reset. So the interrupt handler has
to perform the switch reset, and then re-enable the watchdog
interrupts.
This has been tested using hacked together debugfs code which allows
the "force" bit to be set, so cause a watchdog interrupt.

The switch contains a watchdog looking for issues with the internal
gubbins of the switch. Hook the interrupt the watchdog triggers and
log the value of the control register indicating why the watchdog
fired. The watchdog can only be cleared with a switch reset, which
will destroy the current configuration. Rather than doing this, just
disable the interrupt.
The mv88e6390 family has different watchdog registers. So use an ops
structure, so support for the mv88e6390 family can be added later.
