ath10k: change max RX bundle size from 8 to 32 for sdio
The max bundle size support by firmware is 32, change it from 8 to 32
will help performance. This results in significant performance
improvement on RX path.
The real max rx bundle is decided in ath10k_htc_wait_target(),
it is the min value of HTC_HOST_MAX_MSG_PER_RX_BUNDLE and the value reported
from firmware. So this change shouldn't cause any regressions with other
hardware supported by ath10k.
Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWPZ-1.

ath10k: enable RX bundle receive for sdio
The existing implementation of initiating multiple sdio transfers for
receive bundling is slowing down the receive speed. Combining the
transfers using a bundle method would be ideal.
The transmission utilization ratio for sdio bus for small packet is
slow, because the space and time cost for sdio bus is same for large
length packet and small length packet. So the speed of data for large
length packet is higher than small length.

Hence remove errornous line 5281 to make the driver actually
execute the correct initialization routine for MT7620 chips.
As it was requested by Stanislaw Gruszka remove setting values of
MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
power-safe mode (which is disabled), hence we can drop setting it.
TX_PIN_CFG is set correctly in other functions, and as setting this
value breaks some devices, rather don't set it here during init, but
only modify it later on.

Anirudh refactors the code to reduce the kernel configuration flags and

Maciej does additional refactoring on the configuring of transmit
rings so that we are not configuring per each traffic class flow.
Added support for XDP in the ice driver. Provides additional
re-organizing of the code in preparation for adding build_skb() support
in the driver. Adjusted the computational padding logic for headroom
and tailroom to better support build_skb(), which also aligns with the
logic in other Intel LAN drivers. Added build_skb support and make use

Krzysztof refactors the driver to prepare for AF_XDP support in the
driver and then adds support for AF_XDP.
v2: Updated patch 3 of the series based on community feedback with the
following changes...
- return -EOPNOTSUPP instead of ENOTSUPP for too large MTU which makes
it impossible to attach XDP prog
- don't check for case when there's no XDP prog currently on interface
and ice_xdp() is called with NULL bpf_prog; this happens when user
does "ip link set eth0 xdp off" and no prog is present on VSI; no need
for that as it is handled by higher layer
- drop the extack message for unknown xdp->command
- use the smp_processor_id() for accessing the XDP Tx ring for XDP_TX
action
- don't leave the interface in downed state in case of any failure
during the XDP Tx resources handling
- undo rename of ice_build_ctob

ixgbe: Make use of cpumask_local_spread to improve RSS locality
This patch is meant to address locality issues present in the ixgbe driver
when it is loaded on a system supporting multiple NUMA nodes and more CPUs
then the device can map in a 1:1 fashion. Instead of just arbitrarily
mapping itself to CPUs 0-62 it would make much more sense to map itself to
the local CPUs first, and then map itself to any remaining CPUs that might
be used.
The first effect of this is that queue 0 should always be allocated on the
local CPU/NUMA node. This is important as it is the default destination if
a packet doesn't match any existing flow director filter or RSS rule and as
such having it local should help to reduce QPI cross-talk in the event of
an unrecognized traffic type.
In addition this should increase the likelihood of the RSS queues being
allocated and used on CPUs local to the device while the ATR/Flow Director
queues would be able to route traffic directly to the CPU that is likely to
be processing it.

ice: introduce legacy Rx flag
Add an ethtool "legacy-rx" priv flag for toggling the Rx path. This
control knob will be mainly used for build_skb usage as well as buffer
size/MTU manipulation.
In preparation for adding build_skb support in a way that it takes
care of how we set the values of max_frame and rx_buf_len fields of
struct ice_vsi. Specifically, in this patch mentioned fields are set to
values that will allow us to provide headroom and tailroom in-place.
This can be mostly broken down onto following:
- for legacy-rx "on" ethtool control knob, old behaviour is kept;
- for standard 1500 MTU size configure the buffer of size 1536, as
network stack is expecting the NET_SKB_PAD to be provided and
NET_IP_ALIGN can have a non-zero value (these can be typically equal
to 32 and 2, respectively);
- for larger MTUs go with max_frame set to 9k and configure the 3k
buffer in case when PAGE_SIZE of underlying arch is less than 8k; 3k
buffer is implying the need for order 1 page, so that our page
recycling scheme can still be applied;
With that said, substitute the hardcoded ICE_RXBUF_2048 and PAGE_SIZE
values in DMA API that we're making use of with rx_ring->rx_buf_len and
ice_rx_pg_size(rx_ring). The latter is an introduced helper for
determining the page size based on its order (which was figured out via
ice_rx_pg_order). Last but not least, take care of truesize calculation.
In the followup patch the headroom/tailroom computation logic will be
introduced.

drivers, most importantly with iavf.

When commit
df1c0b8468b3 ("[BRIDGE]: Packets leaking out of

br_fdb_update() it was to avoid learning/refreshing from STP BPDUs, it was
also used to avoid learning/refreshing from user-space with NTF_USE. Those
two tests are done for every packet entering the bridge if it's learning,
but for the fast-path we already have them checked in br_handle_frame() and
is unnecessary to do it again. Thus push the checks to the unlikely cases
and drop them from br_fdb_update(), the new nbp_state_should_learn() helper
is used to determine if the port state allows br_fdb_update() to be called.
The two places which need to do it manually are:
- user-space add call with NTF_USE set
- link-local packet learning done in __br_handle_local_finish()

tipc: improve message bundling algorithm
As mentioned in commit
e95584a889e1 ("tipc: fix unlimited bundling of
small messages"), the current message bundling algorithm is inefficient
that can generate bundles of only one payload message, that causes
unnecessary overheads for both the sender and receiver.
This commit re-designs the 'tipc_msg_make_bundle()' function (now named
as 'tipc_msg_try_bundle()'), so that when a message comes at the first
place, we will just check & keep a reference to it if the message is
suitable for bundling. The message buffer will be put into the link
backlog queue and processed as normal. Later on, when another one comes
we will make a bundle with the first message if possible and so on...
This way, a bundle if really needed will always consist of at least two
payload messages. Otherwise, we let the first buffer go its way without
any need of bundling, so reduce the overheads to zero.
Moreover, since now we have both the messages in hand, we can even
optimize the 'tipc_msg_bundle()' function, make bundle of a very large
(size ~ MSS) and small messages which is not with the current algorithm
e.g. [1400-byte message] + [10-byte message] (MTU = 1500).

In that case, without this patch, openvswitch will traverses all
mask array, because there will be one flow-mask in the tail. This
patch changes the way of flow-mask inserting and deleting, and the
mask array will be keep as below: there is not a NULL hole. In the
fast path, we can "break" "for" (not "continue") in flow_lookup
when we get a NULL flow-mask.
"break"

| M | M | NULL |... | NULL | NULL|

This patch don't optimize slow or control path, still using ma->max
to traverse. Slow path:
* tbl_mask_array_realloc
* ovs_flow_tbl_lookup_exact
* flow_mask_find

net: openvswitch: add flow-mask cache for performance
The idea of this optimization comes from a patch which
is committed in 2014, openvswitch community. The author
is Pravin B Shelar. In order to get high performance, I
implement it again. Later patches will use it.
Pravin B Shelar, says:
| On every packet OVS needs to lookup flow-table with every
| mask until it finds a match. The packet flow-key is first
| masked with mask in the list and then the masked key is
| looked up in flow-table. Therefore number of masks can
| affect packet processing performance.

batman-adv: Axe 'aggr_list_lock'
'aggr_list.lock' can safely be used in place of another explicit spinlock
when access to 'aggr_list' has to be guarded.
This avoids to take 2 locks, knowing that the 2nd one is always successful.
Now that the 'aggr_list.lock' is handled explicitly, the lock-free
__sbk_something() variants should be used when dealing with 'aggr_list'.
