api: ipsec: allow L2 header to be provided in packet
Inline IPsec operation prepends an application provided header to the
IPsec packet before sending the packet out. Allow an application to
provide the header in packet data in front of the plain text IP packet
as an alternative to providing the header through a separate memory
buffer.
