With new design, peer is deleted from hash table in
cdp_peer_delete. Hash table search in dp_peer_can_reuse
API at cdp_peer_create will always fail
Update the peer reuse logic to search from inactive list.
Insert peer to inactive list from cdp_peer_delete() and
in peer reuse case search in inactive list to get
peer.
Also add a new lock to protect peer state transition

The 11g and 11a connections are latency critical and
hence the tx coalescing cannot be applied on traffic
running for these connections.
Add a CDP API to save the number of low latency
connection in the dtapath vdev handle. The Software
latency manager can use this information to decide
and skip the tx register write coalescing for packet
transmission on low latency connections.

Currently the rx tid spinlock is destroyed from
peer delete (based on peer state) or peer unmap handler.
This can lead to a race condition when the peer is
deleted before the peer map command is processed/received.
Fix the above race condition by destroying the rx tid
spinlock only when the peer handle is destroyed/freed.

As part of the VoW IGMP improvements, which deals with
conversion of igmp packets to unicast packets, the
following changes are done when the new feature is enabled:
1. IGMP/MLD packets with special addresses (addresses not
part of any multicast group) will be converted to all
existing clients of the AP. These packets will be
directly fed to igmp multicast to unicast conversion
module.
2. The IGMP/MLD packets with group specific addresses will
first go to multicast enhancement module, where they
will be allowed to pass and will be converted to unicast.
3. The new feature will be enabled only when multicast
enhancement feature is enabled, which will be ensured
at the configuration level.

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.

Add new APIs to iterate through the vdev peer list
by taking the peer reference.
A call back has to be passed to these APIs which will
be called for every peer in the lisst
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

In dp_srng_init, max_buffer_length and prefetch_timer are used
while uninitialized.
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
dereference cmn_init_done.
