For qcn9000, As part HW enhancements, PPDU_ID is sent
in reo_entrance_ring descriptor instead of RX_MPDU_START
tlv. Add support to read ppdu id from descriptor.
Modify existing hal API hal_rx_hw_desc_get_ppduid_get ()
arguments to pass RxDMA ring HW descriptor.
Usage:
a. Use hal_rx_hw_desc_get_ppduid_get () -
to get ppdu id from rx_tlv_hdr or hw descriptor based on target.
for qcn9000, this API gets ppdu_id from HW descriptor,
for other platforms, gets ppdu_id from rx_tv_hdr
b. Use hal_rx_get_ppdu_id () - to get ppdu_id from rx_tlv_hdr

Size of rx_pkt_hdr tlv structure is used to check if there is enough
space in the SKB to add radiotap header.
The issue is seen due to a single SKB can hold the multiple TLVs and
the next subsequent SKB has the data. In this case, there is no headroom
available in the second SKB. Therefore crash seen while adding the
radiotap header in the second SKB.
To fix this issue, check if the SKB has enough headroom space. If not,

With this feature, using appropriate commands, link layer, network layer,
transport layer and some of the application protocols can be tagged with
the user provided tag values for easier identification of protocols. The
supported protocols today are as follows.
ARP, DHCPv4, DHCPv6, DNS over TCP (v4), DNS over TCP (v6), DNS over UDP
(v4), DNS over UDP (v6), ICMPv4, ICMPv6, TCPv4, TCPv6, UDPv4,
UDPv6, IPv4, IPv6, EAP.
Receive packets are tagged by hardware. Tags are applied after the first
matching rule. Hence it is recommended that the rules are
programmed in such a way that tags are configured from application layer
to data link layer to get expected results.
