The interface h->ae_algo->ops->put_vector is called in both
hns3_nic_dealloc_vector_data and hns3_nic_uninit_vector_data in
hns3_client_uninit, this will cause vector freed twice.
This patch remove the Redundant put_vector to make vector freed
only once.

step 1: get vector index.
step 2 unbind ring with vector.
But it gets vector id again in step 2 interface. This patch

Disable periodic stats update background thread and update stats in
background on demand when ndo_get_stats is called.
Having a background thread running in the driver all the time is bad for
power consumption and normally a user space daemon will query the stats
once every specific interval, so ideally the background thread and its
interval can be done in user space..

This patch enables UDP GSO support. We enable this by using two WQEs
the first is a UDP LSO WQE for all segments with equal length, and the
second is for the last segment in case it has different length.
Due to HW limitation, before sending, we must adjust the packet length fields.
We measure performance between two Intel(R) Xeon(R) CPU E5-2643 v2 @3.50GHz
machines connected back-to-back with Connectx4-Lx (40Gbps) NICs.
We compare single stream UDP, UDP GSO and UDP GSO with offload.
Performance:
| MSS (bytes) | Throughput (Gbps) | CPU utilization (%)
UDP GSO offload | 1472 | 35.6 | 8%
UDP GSO | 1472 | 25.5 | 17%
UDP | 1472 | 10.2 | 17%
UDP GSO offload | 1024 | 35.6 | 8%

The driver was suggested for deletion as it implements a subset of the
netdev trigger. It's in the way for further cleanups in the trigger
code but doesn't get an Ack by someone who can actually test and confirm
that the netdev trigger works for can devices. So marking as broken to
get forward with the cleanups.

The poll() changes were not well thought out, and completely
unexplained. They also caused a huge performance regression, because
"->poll()" was no longer a trivial file operation that just called down
to the underlying file operations, but instead did at least two indirect
calls.
Indirect calls are sadly slow now with the Spectre mitigation, but the
performance problem could at least be largely mitigated by changing the
"->get_poll_head()" operation to just have a per-file-descriptor pointer
to the poll head instead. That gets rid of one of the new indirections.
But that doesn't fix the new complexity that is completely unwarranted
for the regular case. The (undocumented) reason for the poll() changes
was some alleged AIO poll race fixing, but we don't make the common case
slower and more complex for some uncommon special case, so this all
really needs way more explanations and most likely a fundamental
redesign.

This is clearly a bug.
We need to set the DMA buffer size in the HW otherwise corruption can
occur when receiving packets.
This is probably not occuring because of small MTU values and because HW
has a default value internally (which currently is bigger than default
buffer size).

The hardcoded values used in ath10k_mac_tx_push_pending and
ath10k_mac_op_wake_tx_queue set an upper limit of how many packets that
can be consumed from the TX queue.
HTC_HOST_MAX_MSG_PER_TX_BUNDLE is a proper name for this constant, as
the value effectively limits the number of messages that can be consumed
in one step. Thus, the value is an upper limit of the number of messages
that can be added to a TX message bundle.

Although the TID mask is 0xf, the modulus operation does still not
produce identical results as the bitwise and operator. If the TID is 15, the
modulus operation will "convert" it to 0, whereas the bitwise and will keep it
as 15.
This was found during code review.

is the root cause of the crash or not, but it seems prudent to
protect it.

There are frames in the ieee80211_txq and there are frames that have
been removed from from this queue, but haven't yet been sent on the wire
(num_pending_tx).
When num_pending_tx reaches max_num_pending_tx, we will stop the queues
by calling ieee80211_stop_queues().
As frames that have previously been sent for transmission
(num_pending_tx) are completed, we will decrease num_pending_tx and wake
the queues by calling ieee80211_wake_queue(). ieee80211_wake_queue()
does not call wake_tx_queue, so we might still have frames in the
queue at this point.
While the queues were stopped, the socket buffer might have filled up,
and in order for user space to write more, we need to free the frames
in the queue, since they are accounted to the socket. In order to free
them, we first need to transmit them.
This problem cannot be reproduced on low-latency devices, e.g. pci,
since they call ath10k_mac_tx_push_pending() from
ath10k_htt_txrx_compl_task(). ath10k_htt_txrx_compl_task() is not called
on high-latency devices.
Fix the problem by calling ath10k_mac_tx_push_pending(), after
processing rx packets, just like for low-latency devices, also in the
SDIO case. Since we are calling ath10k_mac_tx_push_pending() directly,
we also need to export it.

Length of WMI scan message was not calculated correctly. The allocated
buffer was smaller than what we expected. So WMI message corrupted
skb_info, which is at the end of skb->data. This fix takes TLV header

In the case of Station connects to AP with narrower bandwidth at beginning.
And later the AP changes the bandwidth to winder bandwidth, the AP will
beacon with wider bandwidth IE, eg VHT20->VHT40->VHT80 or VHT40->VHT80.
Since the supported BANDWIDTH will be limited by the PHYMODE, so while
Station receives the bandwidth change request, it will also need to
reconfigure the PHYMODE setting to firmware instead of just configuring
the BANDWIDTH info, otherwise it'll trigger a firmware crash with
non-support bandwidth.
The issue was observed in WLAN.RM.4.4.1-00051-QCARMSWP-1, QCA6174 with
below scenario:
AP xxx changed bandwidth, new config is 5200 MHz, width 2 (5190/0 MHz)
disconnect from AP xxx for new auth to yyy
RX ReassocResp from xxx (capab=0x1111 status=0 aid=102)

The *enum* {A|M}PR_BIT were declared in the commit 86a74ff21a7a ("net:
sh_eth: add support for Renesas SuperH Ethernet") adding SH771x support,
however the SH771x manual doesn't have the APR/MPR registers described
and the code writing to them for SH7710 was later removed by the commit
380af9e390ec ("net: sh_eth: CPU dependency code collect to "struct
sh_eth_cpu_data""). All the newer SoC manuals have these registers
documented as having a 16-bit TIME parameter of the PAUSE frame, not
1-bit -- update the *enum* accordingly, fixing up the APR/MPR writes...

The driver was combining XDP_TX virtqueue_kick and XDP_REDIRECT
map flushing (xdp_do_flush_map). This is suboptimal, these two
flush operations should be kept separate.
The suboptimal behavior was introduced in commit 9267c430c6b6
("virtio-net: add missing virtqueue kick when flushing packets").
