[PATCH RFC 0/4] introduce IPsec Operation in virtio-net

[Srujana Challa <schalla@marvell.com>]

This series enhances virtio-net by adding support for IPsec
Operation. These patches aim to extend the capabilities of virtio-net,
enabling it to handle IPsec operations efficiently. This enables
the offloading of IPsec processing, both before transmission
and after reception, thereby providing inline offload
capabilities.

It is using new virtio basic facilities of capability and
resource objects. Below is a summary of the changes introduced:

Patch1:
This patch introduces the foundational support for IPsec within
the virtio-net framework, outlining the necessary capabilities and
resource objects for IPsec operations.

Patch2:
This patch introduces a new selector and action necessary for IPsec
processing, leveraging flow filter actions.

Patch3:
This patch introduces new fields in "struct virtio_net_hdr" to
to support IPsec functionality.

Patch4:
This patch specifies the requirements for both the device and the driver
to support IPsec operations.

These enhancements are for providing support for IPsec within the
virtio-net device/driver, improving security and performance for
virtualized environments. We believe these additions will significantly
benefit users who rely on virtio-net for secure data transmission.

This series references the Virtio-crypto IPsec service operation
capabilities and resource objects data structures, and cryptographic
algorithm definitions to avoid duplication, however the admin command
type vaule differs between Virtio-crypto and Virtio-net.
