Issue has been observed in case of multi segments where mbuf
data gets corrupted due to missing barriers. Changes made to
mbuf just before LMTST by one core gets updatded when the
same mbuf is in use by another core, leading to corruption.
It should be ensured that all changes made to mbuf should be
written before LMTST.

Added new flag for SECURITY in compiler optimized Tx fastpath
framework. With this, compiler autogenerates functions which
have security enabled.

Add support to below TCP segmentation offloads for
96XX A1 onwards and 95xx B0 onwards.
- TCPv4, TCPv6
- VXLAN[v4 | v6][v4 | v6]
- GENEVE[v4 | v6][v4 | v6]
This patch also modifies a fastpath function to be forced
inline due to performance reasons for multi-seg mode.

A huge drop in per core MPPS value was observed when PTP stack is
enabled. The reason behind the bottleneck is HW serialises the
transfer of all SQEs, which seeks timestamp capture, on the same
send DMA path. Hence only those packets which requires timestamp
capture should set SETTSTAMP in send mem alg.
With this patch timestamping would be done only for those packets
with PKT_TX_IEEE1588_TMST set.

Multi segmented packet may be spliced with indirect mbufs also.
Currently driver causes buffer leak for indirect mbufs as they
were not being freed to packet pool.
Patch fixes handling of indirect mbufs for following use cases
- packet contains all indirect mbufs only.
- packet contains mixed mbufs i.e. direct and indirect both.
