drivers/net/ethernet/intel/idpf/idpf.h uses offsetof to
initialize the enum enumerators:

enum idpf_cap_field {
	IDPF_BASE_CAPS = -1,
	IDPF_CSUM_CAPS = offsetof(struct virtchnl2_get_capabilities,
				  csum_caps),
	IDPF_SEG_CAPS = offsetof(struct virtchnl2_get_capabilities,
				 seg_caps),
	IDPF_RSS_CAPS = offsetof(struct virtchnl2_get_capabilities,
				 rss_caps),
	IDPF_HSPLIT_CAPS = offsetof(struct virtchnl2_get_capabilities,
				    hsplit_caps),
	IDPF_RSC_CAPS = offsetof(struct virtchnl2_get_capabilities,
				 rsc_caps),
	IDPF_OTHER_CAPS = offsetof(struct virtchnl2_get_capabilities,
				   other_caps),
};

kernel-doc parses the above enumerator with a ',' inside the
macro and treats 'csum_caps', 'seg_caps' etc. also as enumerators
resulting in the warnings:

drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value
'csum_caps' not described in enum 'idpf_cap_field'
drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value

'rsc_caps' not described in enum 'idpf_cap_field'
drivers/net/ethernet/intel/idpf/idpf.h:130: warning: Enum value
'other_caps' not described in enum 'idpf_cap_field'

Fix it by removing the macro arguments within the parentheses.
