In roam HO failure, peer unmap indication is processed
even before Host initiates the peer cleanup. In the cleanup,
as part of cdp_peer_teardown, AST entries are freed up without
removing it from the peer AST list since get_peer_by_ref_id
returns NULL peer pointer as peer is moved to inactive state.
Fix is to delete peer AST entries as part of peer unmap
indication so that the entries are removed from the AST list.

STATUS_BUFFER_DONE tlv written in first word for a status
buffer indicates that DMA is done for that status ring entry.
In existing implementation, for a status ring entry if
STATUS_BUFFER_DONE tlv is not written by HW, we poll on to status ring
entry until DMA is done by HW.
During lmac reset it may happnen that HW will not write STATUS_BUFFER_DONE
tlv in status buffer, in that case we end up polling infinitely leading
to backpressure on monitor status ring.
As per MAC team's suggestion, when HP + 1 entry is peeked and if DMA
is not done and if HP + 2 entry's DMA done is set,
replenish HP + 1 entry and start processing in next interrupt.
If HP + 2 entry's DMA done is not set,
poll onto HP + 1 entry DMA done to be set.

a. full_mon_mode ini param
b. QCA_SUPPORT_FULL_MON compile time macro
Currently enabling full monitor is not taken care under

As monitor mode is not supported for 256M profile,
QCA_SUPPORT_FULL_MON is disabled.
Enable full monitor mode when both ini and macro are enabled.

Add new APIs to iterate through the vdev peer list
by taking the peer reference.

dp_vdev_iterate_peer() -> iterates through peer_list of vdev
dp_pdev_iterate_peer() -> iterates through peer_list of all
vdevs in pdev
dp_soc_iterate_peer() -> iterates through peer_lists of all vdevs
in soc
Additonal APIs are added to for itearations where the callback
will be called outside the vdev->peer_list_lock, as these APIs
have additional memory allocations suggested to use only in case
the iteration need to happen outside lock

UPDATE_RX_REO_QUEUE commands are queued in the REO_CMD
ring as part of peer cleanup for each tid. The cb

these entries from the freelist are processed as part

In dp_srng_init, max_buffer_length and prefetch_timer are used

In dp_bucket_index, overrunning array cdp_sw_enq_delay leads to
out-of-bounds access.
In dp_rx_defrag_fraglist_insert, cur is first NULL checked but
cur is again set to qdf_nbuf_next and is accessed without
NULL check. Thus do a NULL check again before dereferencing
cur to avoid potential NULL pointer dereference.
In htt_t2h_stats_handler, soc could be NULL while cmn_init_done
is dereferenced. Thus fix it by NULL check soc first and then
