net/mlx5: Add MACsec offload Tx command support
This patch adds support for Connect-X MACsec offload Tx SA commands:
add, update and delete.
In Connect-X MACsec, a Security Association (SA) is added or deleted
via allocating a HW context of an encryption/decryption key and
a HW context of a matching SA (MACsec object).
When new SA is added:
- Use a separate crypto key HW context.
- Create a separate MACsec context in HW to include the SA properties.
Introduce a new compilation flag MLX5_EN_MACSEC for it.
Follow-up patches will implement the Tx steering.
