03a9f5b19c qcacmn: Add framework to configure varying data/monitor buf size
Add a framework to configure varying buffer size for both data and monitor
buffers.
For example, with this framework, the user can configure 2K SKB for Data
buffers, monitor status rings, monitor descriptor rings, monitor
destination rings and 4K SKB for monitor buffers through compile time.

d13ed3e9e1 qcacmn: API support for AST flow override
Lithium HW can parse each MSDU when packets are enqueued to transmit
classifier and each MSDU can get enqueued to different MSDU-Queue.
By default, there are 2 queues per TID – UDP and NON-UDP. Based on
the flow parsing, packets will be queued to either of them.
Enterprise customers uses RAW mode frames which transmit classifier
would not be able to identify L4 protocol for  UDP or NON-UDP queue
for encrypted frames.
Customer can also have different application based packets which needs
to be enqueued to differently prioritized queues. They can choose to
tag each MSDU based on application DPI and derive the flow priority
as below –
•	UDP
•	NON-UDP
•	HI-PRIO
•	LOW-PRIO
Customer needs API support from host which will provide an ast-index
based on a particular flow id given peer mac address. Based on the mac
address, host will find the associated peer and return the ast_index &
cache set number corresponding to the flow id from peer flow based ast
entry table. Customer will then program this ast-index and ast override
in transmit classifier CMD ring to enqueue MSDU to a specific
flow-queuein TQM.
Host API:
Input parameter – uint8_t *peer mac address, uint8_t flow id
Output – uint16_t ast_index

0b92469595 qcacmn: fix invalid accessing to rx_tlv_hdr due to scattered msdu
long length msdu is received and looks this msdu is spread across
multiple nbufs, there is no corresbonding logic for this case.
qdf_set_pkt_len will invoke pskb_expand_head to renew skb->head
buffer, but the rx_tlv_hdr is still pointed to original skb->data
buffer, invalid accessing will happen.
  As a WAR, drop this msdu related nbufs after dp_rx_sg_create is done.

3222184e14 qcacmn: fix RX desc is using but freed back to pool
Crash scenario:
(1) frag data A is dropped and related RX desc A is replenished
and reused, but pdev->free_list_tail is still pointed to RX desc A.
(2) frag data B/C is coming, defrag fails then pdev->free_list_head
will point to B-->C RX desc, but pdev->free_list_tail still point to A.
(3) for defrag failing case, host only will replenish 1 RX buffer for
current case, RX desc B is replenished, while C will be free back to
RX desc pool.
(4) dp_rx_add_desc_list_to_free_list will set RX desc A-->next =
free_list, free_list point to C insted.
(5) when step (1) RX desc A replenished buffer indicated to host by
REO2Dst ring, RX desc A -->nbuf actually is pointed to another RX
desc, invalid skb accessing will happen.

Solution:
a. reset tail pointer in dp_rx_add_desc_list_to_free_list at last.
b. reset tail pointer same as head in dp_rx_add_to_free_desc_list
if head->next is NULL.
c. set correct rx_bufs number for replenish when dp_rx_defrag fails.

0f0a36c8d4 qcacmn: Change info/err prints to debug in roaming path
The printk buffer is protected by a global raw spinlock for readers
and writers. This restricts the contexts that are allowed to
access the buffer. So large latencies exists when printing to
kmsg done with QDF trace levels WARN, INFO, ERROR. This results
in roaming KPI for maximum transition time exceeding the expected
100ms.
So change info/err prints to debug prints in roaming path
to reduce delays in roaming time.

0181445b71 qcacmn: fix dp_tx_desc invalid accessing due to race condition
crash scenario:
  a. dp_tx_vdev_detach will reset the vdev of TX desc to NULL
by dp_tx_desc_flush.
  b. in the meantime, if TX completion is coming and when all TX desc
is recycled, the pool will be freed if pool status is invalid before.
  c. invalid TX desc accessing will happen in (a).

add TX desc pool lock protection in dp_tx_desc_flush.
