For certain wlan chips, eg WCN7850, all the REO error
codes are routed to the APPS core and none are handled
by the firmware.
Add support to handle all the REO errors. Currently for
all the newly handled REO errors, the packet is dropped
and the corresponding link descriptor is returned to the WBM.

Currently the detection of whether a frame arriving on the
rx-error ring is done via the flags in the ring descriptor.
For targets which support providing previous PN in the
rx-error ring descriptor, the flags indicating BAR frame
will not be present in the ring descriptor.
Add BAR frame check and handling in the OOR and 2K-jump
frame processing handlers.

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.

Currently the error_code is not passed as an argument
for BAR frame handling. Due to this, if a BAR frame is
received which is OOR or 2K-jump frame, then the sequence
number from the BAR frame is not programmed to the REO.
This can eventually lead to failure in re-ordering of
the subsequent data frames.
Pass the proper error code for BAR frame handling.

Smart monitor mode requires buffers on monitor status ring only.
