net-qdisc-hhf: Heavy-Hitter Filter (HHF) qdisc
This patch implements the first size-based qdisc that attempts to
differentiate between small flows and heavy-hitters. The goal is to
catch the heavy-hitters and move them to a separate queue with less
priority so that bulk traffic does not affect the latency of critical
traffic. Currently "less priority" means less weight (2:1 in
particular) in a Weighted Deficit Round Robin (WDRR) scheduler.
In essence, this patch addresses the "delay-bloat" problem due to
bloated buffers. In some systems, large queues may be necessary for
obtaining CPU efficiency, or due to the presence of unresponsive
traffic like UDP, or just a large number of connections with each
having a small amount of outstanding traffic. In these circumstances,
HHF aims to reduce the HoL blocking for latency sensitive traffic,
while not impacting the queues built up by bulk traffic. HHF can also
be used in conjunction with other AQM mechanisms such as CoDel.
To capture heavy-hitters, we implement the "multi-stage filter" design
in the following paper:
C. Estan and G. Varghese, "New Directions in Traffic Measurement and
Accounting", in ACM SIGCOMM, 2002.
Some configurable qdisc settings through 'tc':
- hhf_reset_timeout: period to reset counter values in the multi-stage
filter (default 40ms)
- hhf_admit_bytes: threshold to classify heavy-hitters
(default 128KB)
- hhf_evict_timeout: threshold to evict idle heavy-hitters
(default 1s)
- hhf_non_hh_weight: Weighted Deficit Round Robin (WDRR) weight for
non-heavy-hitters (default 2)
- hh_flows_limit: max number of heavy-hitter flow entries
(default 2048)
Note that the ratio between hhf_admit_bytes and hhf_reset_timeout
reflects the bandwidth of heavy-hitters that we attempt to capture
(25Mbps with the above default settings).
The false negative rate (heavy-hitter flows getting away unclassified)
is zero by the design of the multi-stage filter algorithm.
With 100 heavy-hitter flows, using four hashes and 4000 counters yields
a false positive rate (non-heavy-hitters mistakenly classified as
heavy-hitters) of less than 1e-4.

====================
Intel Wired LAN Driver Updates
This series contains updates to i40e, ixgbevf, ixgbe and igb.
Don provides an ixgbevf patch to add DCB configuration into the queue
setup so that we won't have to allocate queues in a separate place when
enabling DCB.
Guenter Roeck provides 2 patches for ixgbe to simplify the code by
attaching hwmon sysfs attributes to hwmon device instead of PCI device.
Also fix an issues where the temperature sensor attribute index was
being started with the value 0 and not 1 as per the hwmon API.
Carolyn provides igb patches to fix queue allocation method to
accommodate changes during runtime. This includes changing how the
driver initializes MSIx and checks for MSIx configuration to make it
easier to reconfigure the device when queue changes happen at runtime.
Neerav and Shannon fixes i40e debugfs commands that dump hex information
by using print_hex_dump().
Shannon provides several i40e fixes which include the prevention of
null pointer exception in the dump descriptor by checking that rings
were allocated before trying to reference them. Fixed up a couple of
scanfs to accept various base numbers instead of silently requiring hex.
Anjali fixes up i40e where the incorrect defines were being used for
misc interrupts.
Alan Cox provides a fix for i40e where we assume that the resulting
buffer is zero terminated when we then re-use it. The sscanf is limited
to 512 bytes but needs to be 511 to allow for a terminator.
Stephen Hemminger fixes i40e by making local functions static and removes
unused code (i40e_aq_add/remove_vlan() functions).

When changing number of queues using ethtool's set_channels during runtime,
a queue allocation could fail, which can leave the device in a down state.
In order to preserve the usability of the device in this scenario, this patch
changes the driver to allocate the number of queues only if they have not
been allocated already. The first allocation is then done for the max number
of queues, which is the default queues for this driver. With this change,
queue quantity changes are not subject to queue allocation failures.

bna: Handle the TX Setup Failures
Change details:
- When bnad_setup_tx() returns NULL, the error is NOT returned to the caller.
The caller will incorrectly assume success. So Return ENOMEM when bna_tx_create()
fails.
- If bnad_tx_msix_register() fails, call bna_tx_destroy() to free tx & to NULL
the bnad reference to tcb.

bna: Add NULL Check Before Dereferencing TCB
Currently we already check to see whether the BNAD_TXQ_TX_STARTED cleared.
But if the tcb structure which contains this flag is also already freed by that
time, we would dereference the NULL pointer. This patch is to check tcb for NULL
pointer, before dereferencing it.

bna: Enable Multi Buffer RX
The CT2 HW supports multi-buffer Rx. This patch provides the necessary changes
for bnad to use multi-buffer Rx feature. For BNAD, multi-buffer Rx is by
default enabled when MTU is > 4096. For >4096 MTU, q0 data/large buffers are of
2048 size. As the resource requirements of multi-buffer Rx are different new Rx
needs to be created to use this feature. ASIC posts multiple completions if
frame exceeds buffer size. The last completion is marked with EOP flag.
- Separate HQ and DQ enums for resource allocations and configurations.
- rx_config and rxq structure changes to pass the correct info from bnad.
- DQ depth need not be same as HQ depth. So CQ depth is adjusted accordingly.
- Rx CFG frame size is taken from configured MTU.
- Rx q0 buffer size is configured from bnad s rx_config when multi-buffer is
enabled.
- Poll for entire frame completion.
- Once EOP completion is received gather the number of vectors used by the
frame to submit it to the stack.
- Changed MTU to frame size wherever necessary.

bna: RX Filter Enhancements
Change Details:
- Added bna_rx_ucast_listset() for synchronous ucast listadd operation.
- Clear mac->handle before adding it to free_q.
- bnad_set_rx_mode() rewritten. bnad_set_rx_mode() adds the MACs in uc_list
to UCAM. If it exceeds the max supported, DEFAULT mode is turned on. If
MCAM limit is exceeded, ALLMULTI mode is turned on.
- Clear CF flags, check for the new mode and reprogram the Rx approach.
- Added bnad_set_rx_ucast_fltr() and bnad_set_rx_mcast_fltr().
- Check for IFF_PROMISC to set the correct mode.

bna: Fix Filter Add Del
Change Details:
- bna_rx_mcast_listset() API first looks at free_q only and not at other
pending Qs rendering it non-deterministic of giving an upper limit.
Modify bna_rx_mcast_listset() implementation to not use only half of the
limit.
- Allocate and initialize queue for deleting
- Segregate the adding and deleting process by using separate queues.
- The filter framework in bna does not let adding addresses to its max capacity
due to asynchronous operations involved.
Provide a synchronous option to set a given list.
