Configure hardware address and also active the function. When a function is
Support port function commands to enable / disable IPsec crypto offloads, this is used to control the port IPsec device capabilities. When IPsec crypto capability is disabled for a function of the port (default), function cannot offload IPsec operation. When enabled, IPsec operation can be offloaded by the function of the port. Enabling IPsec crypto offloads lets the kernel to delegate XFRM state processing and encrypt/decrypt operation to the device hardware. 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 Signed-off-by: Dima Chumak <dchumak@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> --- devlink/devlink.c | 18 ++++++++++++++++++ man/man8/devlink-port.8 | 13 +++++++++++++ 2 files changed, 31 insertions(+)
