Currently the EAPOL/ARP/DHCP frames arriving as 2K-jump
or out-of-order frmaes are being delivered to the network
stack, without checking for the packet-number sequence.
WCN7850 has hardware support to provide the packet number
of the previous successful re-ordered packet from hardware.
Use this feature to check if the packet-number are in proper
sequence for these EAPOL/ARP/DHCP packets arriving as 2k-jump
or out-of-order packets before submitting it to the network
stack.

Only BAR frames with REO/RXDMA push reason as error are handled
in host. FP BAR frames without errors, are routed to host
via REO/RXDMA with push reason as route.
Instead of leaking the buffer, handle the routed BAR frames

cases.

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.

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

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
dp_vdev_iterate_peer_lock_safe()
dp_pdev_iterate_peer_lock_safe()

Rx desc pool have a flag to identify whether frag or nbuf
operation needs to be performed for alloc, map, prep and
free buffer for monitor dest buffer.
This flag will be set only for mon destination desc pool,
if RX_MON_MEM_FRAG feature is enabled.
In all other case, It will be set to Zero and default nbuf
operation will be taken.
This flag get initialized at the time of pdev rx_desc_pool
initialization and gets reset while pdev deinit.
Mon destination buffer will have support for frag if
RX_MON_MEM_FRAG flag is set.
