Currently when IPA is enabled, all RX frames will be routed to IPA
ring REO2SW4 by default, there is no REO2HOST option. once IPA RX/TX
is slow, then likely will give RX back pressure to wlan RXDMA. per
FW feature request, when IPA RX is slow or stuck, route RX frames to
wlan host to mitigate issue, thus provide REO2SW1 ring as REO_DST
option into HWIO_REO_R0_DESTINATION_RING_CTRL_IX_0.
To make sure if without FW dynamic REO_DST ring switching change,
current host change should not give chance that RX frames
route to host when IPA is enabled, select CTRL_IX_0 index 2 to
set REO_DST option, the reason is: if RX hash is enabled, CTRL_IX_2
and CTRL_IX_3 index 16~31 is REO_DST option filled with REO2SW4,
if RX hash is disabled, then CTRL_IX_0 index 1 and 4 filled with
REO2SW4 is REO_DST option configured by
WMI_HOST_PEER_SET_DEFAULT_ROUTING, so CTRL_IX_0 index 2
is only used for FW dynamic ring switching.

In the scanerio where peer teardown and peer map happen
in parallel, AST entries could get added to the peer AST
list after cleanup happens as part of peer teardown. AST
cleanup as part of peer unmap handling would not remove
the entry from the peer AST list. This is because
dp_peer_get_ref_by_id returns NULL as peer state is moved
to logically deleted state.
Fix is to not take peer ref by id and use the peer
argument passed in which already holds ref in the
peer unmap handling.

In the scenario where htt packets fail to be transmitted to
FW, they are added in both endpoint tx queue and misc list.
On receiving FW down indication before these packets are sent
to FW, endpoint tx queue is flushed and nbufs are freed. Post
this, the aforementioned nbufs would be unmapped/freed again in
htt_htc_misc_pkt_pool_free causing panic.
Fix is to free the nbuf via misc pool free only when the magic
pattern is set.

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.

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.
