Introduce qdf wrapper API
1. frag is added to nbuf fragment array. If frag can't be fit in that nbuf
a new nbuf is allocated and frag is added to the new nbuf. Once added
nbuf is added as a fraglist to head nbuf. On a subsequent call, frag is
added to the last nbuf in a fraglist.
2. get reference for fragment.

In function qdf_fill_wlan_connectivity_log, the unsupported EAPOL
packet types are not dropped.This results in setting the
log_subtype to invalid value zero and the log buffer being forwarded
to wlan_connectivity_log_enqueue. The fix is to drop the unsupported
packets by returning from the function.
The local variable log_buf,of type struct wlan_log_record, is not
null initialized.This could cause some of the member elements to have
unexpected values.This fix is to null initialize the log_buf structure.

Memory allocation in atomic context is not correct, as for
MEMORY_DEBUG profile the initial_memory_debug flag is set to

Issue is seen with SDX_PINE where the memory allocation is done
in sleeping context using GFP_KERNEL in interrupt context
Fix is create a new memory allocation API with GFP_ATOMIC flag

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.

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,

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.
