In Beryllium the HW does the ast lookup and match
and sets the intra-bss bit in the msdu_desc_info
structure of reo_destination ring and WBM Rx release ring.
So, change the Beryllium code to make use of this
hardware assistance for intra-bss.

When a msdu scattered across multiple nbufs is received
in REO2SW ring and the remaining nbufs are not yet
available in the ring, loop in dp_rx_process is exited
without resetting the invalid bit in the ring desc cookie.
This will result in an incorrect assertion failure when
the same entry is processed the next time.
Fix is to reset the invalid bit in ring desc cookie
when the loop is exited in the above msdu scattered
scenario.

When the STA network interface receives such packets
from bridge and send it to the AP, it is echoed back

Currently all the rx ring descriptor contents are left
intact even after these entries are processed. This can,
at times, lead to stale entries being processed, if the
head pointer of any ring is updated before the updated
contents of the ring descriptor gets reflected in the memory.
This can lead to scenarios where the host driver reads a
stale value of sw_cookie, and free/unmap a currently in-use
buffer, thereby leading to the hardware accessing unmapped
memory region.
The sw_cookie is the integral part of al the rx ring
processing. Hence we always mark the sw_cookie as invalid
after dequeuing an entry from the REO2SW ring. Every time
we check for the validity of the sw_cookie before we try to
process an entry from REO2SW ring. if the invalid bit in the
sw_cookie is set, we just skip this entry and move on to the
next entry in the ring.

The peer rx packets should be flushed when
deleting the peer and its state should be reset
to DISCONNECT, when deleting the peer.
If the state of peer is not set to DISCONNECT,
then the flushing of rx packets for the peer
which is being deleted will call the rx callback
and submit these packet to the stack, which can
cause unwanted behaviour.
This way the UMAC does not need to specifically
call clear peer before deleting the peer.
