This change is for supporting monitor mode VAP. All the monitor mode ring
is configured. The related monitor mode ring includes:
-monitor mode buffer ring
-monitor mode destination ring
-monitor mode status ring
-monitor mode link descriptor ring
The packet is not sent to monitor mode ring unless the monitor mode VAP is
configured. This release support Multiple VAP - AP/STA VAP plus Monitor
VAP configuration. The status ring is not used in this release. However,
the ring is tested and the ring is moving and there are TLV's in the ring.

When a packet is generated internally, host adds a debug
node entry to the table and deletes the entry once received
tx completion for that packet by calling qdf_nbuf_free.
But when a packet is coming from network stack, host doesn’t
add any debug entry to the table and on receiving tx completion,
it calls qdf_nbuf_tx_free which will simply free the skb.
In case of P2P GO mode where packets are forwarded internally,
host creates a private copy of skb and add debug node entry in
the table. But when receiving a tx completion for the same packet
host calls qdf_nbuf_tx_free which will free the skb but will not
remove this node entry from the table. Currently, this api is common
for all data tx completion packets.
Add an extra flag in control block to differentiate whether skb is
generated by driver or come from network stack. If flag is true,
that means generated internally and need to remove the entry from
debug node table.

In current codeflow, we are maintaining the length of the TSO segments
belonging to one jumbo packet inside tso_info, which is common for
all the segments of one jumbo packet. This works if the length of
the segments (frag[1]) is the same. In case it is not, it ends up
assigning incorrect length to all the segments. This is resulting
GMS login failure.
Fix issue by maintaining the total length of the segment in the
qdf_tso_seg_t structure.
