ice: Implement virtchnl commands for AVF support

virtchnl is a protocol/interface specification that allows the Intel "Adaptive Virtual Function (AVF)" driver (iavf.ko) to work with more than one physical function driver. The AVF driver sends "virtchnl commands" (control plane only) to the PF driver over mailbox queues and the PF driver executes these commands and returns a result to the VF, again over mailbox. This patch adds AVF support for the ice PF driver by implementing the following virtchnl commands: VIRTCHNL_OP_VERSION VIRTCHNL_OP_GET_VF_RESOURCES VIRTCHNL_OP_RESET_VF VIRTCHNL_OP_ADD_ETH_ADDR VIRTCHNL_OP_DEL_ETH_ADDR VIRTCHNL_OP_CONFIG_VSI_QUEUES VIRTCHNL_OP_ENABLE_QUEUES VIRTCHNL_OP_DISABLE_QUEUES VIRTCHNL_OP_ADD_ETH_ADDR VIRTCHNL_OP_DEL_ETH_ADDR VIRTCHNL_OP_CONFIG_VSI_QUEUES VIRTCHNL_OP_ENABLE_QUEUES VIRTCHNL_OP_DISABLE_QUEUES VIRTCHNL_OP_REQUEST_QUEUES VIRTCHNL_OP_CONFIG_IRQ_MAP VIRTCHNL_OP_CONFIG_RSS_KEY VIRTCHNL_OP_CONFIG_RSS_LUT VIRTCHNL_OP_GET_STATS VIRTCHNL_OP_ADD_VLAN VIRTCHNL_OP_DEL_VLAN VIRTCHNL_OP_ENABLE_VLAN_STRIPPING VIRTCHNL_OP_DISABLE_VLAN_STRIPPING Signed-off-by: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
