Use CONFIG_CNSS_OUT_OF_TREE to control if CNSS prealloc driver is
built from in-kernel-tree source or out-of-kernel-tree source since
the exposed header file will be in different paths. This is also for
backward compatibility. Use internal flag CNSS_MEM_PRE_ALLOC instead
of CONFIG_WCNSS_MEM_PRE_ALLOC which will not be defined from kernel
defconfig for out-of-kernel-tree CNSS prealloc driver. CNSS_MEM_PRE_
ALLOC will be defined in the driver Kbuild no matter where CONFIG_
WCNSS_MEM_PRE_ALLOC gets defined.

There is a requirement to get sequence number and tid for tx
data packets in packet capture mode. These fields are not
received as part of WBM tx completion, but are obtained from
FW in ppdu stats. As WBM tx completion and FW ppdu stats are
two different events, the ppdu_stats of previously sent ppdu
are filled in the radiotap header of current tx ppdu in packet
capture mode.
Enhance code to add required fields such as ppdu_id of tx current
ppdu and ppdu_id, tid, start_seq, ba_bitmap of previously sent ppdu
as extension2 to radiotap header. These fields will be added in
radiotap header only when add_rtap_ext2 is set.

In qdf_mem_multi_page_link, pages->cacheable_pages is array with elem num
pages->num_pages, but pages->cacheable_pages[pages->num_pages] is read,
out of bounds error will report if KASAN enabled.
When ini dp_tx_ext_desc is 6144 and DP_TX_DESC_POOL_SIZE is 6144,
Size in bytes of TX TSO Num Seg Desc is 16, page size is 4096, so TX TSO
Num Seq Desc need 24 pages (6144*16/4096), each address need 8 bytes,
so TSO Num Seq Desc need kmalloc 192 bytes to save address of 24 pages.

Tx data transfer in host mode with nbuf map_unmap debug frmwk
enabled and enhanced stats disabled results in an assert.
This is because on Tx completion path, nbuf unmap is done using API
qdf_mem_unmap_nbytes_single which takes physical address of nbuf
for unmap and does not remove nbuf from map_unmap tracking list and
when nbuf is freed, it results in assert as the tracking list still
contains that nbuf entry.
In order to fix this, define a new API for nbuf unmap passing physical
and virtual address of nbuf as arguments. Physical address is passed
as an argument in order to avoid cache miss in per packet path which
eventually helps in improving the KPI.
