Check if REO ring is near full at the end of dp_rx_process. In case the
ring is near full, reap the packets in the ring (and replenish, send to
upper layer) until the quota allows. Ignore the HIF yield time
limit in such cases.
This change is needed to prevent back pressure from the REO ring(in case
it gets full). Backpressure from REO ring (to LMAC) may lead to a
watchdog and eventually a FW crash. Hence, avoid such a scenario by
reaping as many packets as the 'quota' allows when the REO ring is in
aforementioned condition.
A sid-effect of this change would be that at times the RX softirq may run
longer (till the quota limit) than the configured HIF yield time.
However, this logic is not expected to kick-in in perf builds. The issue
is reported for a defconfig build where lots debug options are enabled
in the kernel which can slow the processing down.

While handling a frag with no peer, donot set packet length as this is
already done while handling the fragment before re-injection into the
REO. Without this, qdf_nbuf_set_pktlen will fail while doing a skb_put
on a non-linear packet.
Also, donot use L2 header offset while doing a pull head for the RX frag.

In the present scenario, in case of Multicast Enhancement when
the multicast packet is received the packet is converted to
unicast packet and send to list of clients in the hyfi table.
During conversion descriptors get allocated from ME pool
for each client and the Tx MSDU descriptor is send to HW
for transmit. On TX completion descriptors are freed and
added back to ME pool.
But if the HW enqueue is failed then the current TX descriptor
is freed and added back to ME pool. But the remaining descriptor
are neither retried nor freed thus resulting in Host Asserted
Crash.
So, adding a fix that if the HW enqueue is failed for ME packet,
free that descriptor and retry HW enqueuing for the remaining
descriptors.

Currently for REO reinject path, first fragment is in the
linear part of the skb buffer while other fragments are
appended to skb buffer as non-linear paged data. The other
point is that for REO reinject buffer, l3_header_padding is
not there, meaning ethernet header is right after struct
rx_pkt_tlvs.
Above implementation will have issues when WLAN IPA path is
enabled.
Firstly, IPA assumes data buffers are linear. Thus need to
linearize skb buffer before reinjecting into REO.
Secondly, when WLAN does IPA pipe connection, RX pkt offset
is hard-coded to RX_PKT_TLVS_LEN + L3_HEADER_PADDING. Thus
need to pad L3_HEADER_PADDING before ethernet header and
after struct rx_pkt_tlvs.

At present this counter is of type uint8_t and hence can
accumulate till 256 counter but num_stats is of type uint32_t.
Hence if remainting stats to be precessed is 256 then rem_stats
value will be 0 as it will only consider LSB 8 BITS and it will
result in stats mismatch and hence memory leak.

Rx defrag waitlist was not getting cleared during dp_peer_rx_cleanup in
the case of STA mode even though the tid was getting deleted. This
created a scenario where the next time dp_rx_defrag_waitlist_remove was
called, it was trying to access now invalid memory. If a vdev was
disconnected in the middle of receiving traffic, then the tid would be
deleted but the rx frag waitlist would not. Upon reconnecting, the
reception of the next frag would cause a crash due to the now invalid
memory in the waitlist.

In cases where one of the interfaces is a P2P-GO and
IPA has been enabled, the P2P connection establishment
fails.
When IPA is enabled, the REO destination is changed to REO4
which can be reaped only by IPA module. But in case of P2P-GO
interface in operation, this change in configuration causes
all the RX packets to be stalled due to incorrect REO configuration.
Hence, to avoid this case, do not change the REO dest config
when the interface subtype is P2P.
