cd5b860c18 ipsec: support header construction
Add support for RFC 4301(5.1.2) to update of
Type of service field and Traffic class field
bits inside ipv4/ipv6 packets for outbound cases
and inbound cases which deals with the update of
the DSCP/ENC bits inside each of the fields.

8734e669fc ipsec: include high order bytes of ESN in packet length
When esn is used then high-order 32 bits are included in ICV
calculation however are not transmitted. Update packet length
to be consistent with auth data offset and length before crypto
operation. High-order 32 bits of esn will be removed from packet
length in crypto post processing.

e95291f019 ipsec: support multi-segment packets
Add support for packets that consist of multiple segments.
Take into account that trailer bytes (padding, ESP tail, ICV)
can spawn across multiple segments.

874cbe577b ipsec: reorder packet process for ESP inbound
Change the order of operations for esp inbound post-process:
- read mbuf metadata and esp tail first for all packets in the burst
  first to minimize stalls due to load latency.
- move code that is common for both transport and tunnel modes into
  separate functions to reduce code duplication.
- add extra check for packet consitency

a41a33c550 ipsec: reorder packet check for ESP inbound
Right now check for packet length and padding is done inside cop_prepare().
It makes sense to have all necessary checks in one place at early stage:
inside pkt_prepare().
That allows to simplify (and later hopefully) optimize cop_prepare() part.

6015e6a133 ipsec: move inbound and outbound code
sa.c becomes too big, so decided to split it into 3 chunks:
 - sa.c - control path related functions (init/fini, etc.)
 - esp_inb.c - ESP inbound packet processing
 - esp_outb.c - ESP outbound packet processing

Plus few changes in internal function names to follow the same
code convention.
No functional changes introduced.
