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,
drop the frame.

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.
