net/i40e: fix VF RSS configuration
The kernel driver supports VF RSS configuration message "VIRTCHNL_OP_GET_RSS_HENA_CAPS and VIRTCHNL_OP_SET_RSS_HENA", this patch adds PMD support for these messages. Fixes: b81295c474b0 ("net/i40e: add user callback for VF to PF message") Cc: stable@dpdk.org Signed-off-by: Alvin Zhang <alvinx.zhang@intel.com> Acked-by: Beilei Xing <beilei.xing@intel.com>
