Currently rte_security_set_pkt_metadata() and rte_security_get_userdata()
methods to set pkt metadata on Inline outbound and get userdata
after Inline inbound processing is always driver specific callbacks.
For drivers that do not have much to do in the callbacks but just
to update metadata in rte_security dynamic field and get userdata
from rte_security dynamic field, having to just to PMD specific
callback is costly per packet operation. This patch provides
a mechanism to do the same in inline function and avoid function
pointer jump if a driver supports the same.

Not all net PMD's/HW can parse packet and identify L2 header and
L3 header locations on Tx. This is inline with other Tx offloads
requirements such as L3 checksum, L4 checksum offload, etc,
where mbuf.l2_len, mbuf.l3_len etc, needs to be set for HW to be
able to generate checksum. Since Inline IPsec is also such a Tx
offload, some PMD's at least need mbuf.l2_len to be valid to
find L3 header and perform Outbound IPSec processing.
Hence, this patch updates documentation to enforce setting
mbuf.l2_len while setting PKT_TX_SEC_OFFLOAD in mbuf.ol_flags
for Inline IPsec Crypto / Protocol offload processing to
work on Tx.

A learner table is typically used for learning or connection tracking,
where it allows for the implementation of the "add on miss" scenario:
whenever the lookup key is not found in the table (lookup miss), the
data plane can decide to add this key to the table with a given action
with no control plane intervention. Likewise, the table keys expire
based on a configurable timeout and are automatically deleted from the
table with no control plane intervention.

Added look-ahead instruction to read a header from the input packet
without advancing the extraction pointer. This is typically used in
correlation with the special extract instruction to extract variable
size headers from the input packet: the first few header fields are
read without advancing the extraction pointer, just enough to detect
the actual length of the header (e.g. IPv4 IHL field); then the full
header is extracted.

The rte_vhost_driver_unregister() and vhost_user_read_cb()
can be called at the same time by 2 threads.
when memory of vsocket is freed in rte_vhost_driver_unregister(),
the invalid memory of vsocket is accessed in vhost_user_read_cb().
It's a bug of both mode for vhost as server or client.
E.g., vhostuser port is created as server.
Thread1 calls rte_vhost_driver_unregister().
Before the listen fd is deleted from poll waiting fds,
"vhost-events" thread then calls vhost_user_server_new_connection(),
then a new conn fd is added in fdset when trying to reconnect.
"vhost-events" thread then calls vhost_user_read_cb() and
accesses invalid memory of socket while thread1 frees the memory of
vsocket.
E.g., vhostuser port is created as client.
Thread1 calls rte_vhost_driver_unregister().
Before vsocket of reconn is deleted from reconn list,
"vhost_reconn" thread then calls vhost_user_add_connection()
then a new conn fd is added in fdset when trying to reconnect.
"vhost-events" thread then calls vhost_user_read_cb() and
accesses invalid memory of socket while thread1 frees the memory of

The fix is to move the "fdset_try_del" in front of free memory of conn,
then avoid the race condition.
