devlink: Expose port function commands to control IPsec crypto offloads
Expose port function commands to enable / disable IPsec crypto offloads,
this is used to control the port IPsec capabilities.
When IPsec crypto is disabled for a function of the port (default),
function cannot offload any IPsec crypto operations (Encrypt/Decrypt and
XFRM state offloading). When enabled, IPsec crypto operations can be
offloaded by the function of the port.
Example of a PCI VF port which supports IPsec crypto offloads:
$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
function:
hw_addr 00:00:00:00:00:00 roce enable ipsec_crypto disable
$ devlink port function set pci/0000:06:00.0/1 ipsec_crypto enable
$ devlink port show pci/0000:06:00.0/1
pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0
function:
hw_addr 00:00:00:00:00:00 roce enable ipsec_crypto enable
