+ * struct fcoe_ctlr - FCoE Controller and FIP state.
+ * @state: internal FIP state for network link and FIP or non-FIP mode.
+ * @lp: &fc_lport: libfc local port.
+ * @sel_fcf: currently selected FCF, or NULL.
+ * @fcfs: list of discovered FCFs.
+ * @fcf_count: number of discovered FCF entries.
+ * @sol_time: time when a multicast solicitation was last sent.
+ * @sel_time: time after which to select an FCF.
+ * @port_ka_time: time of next port keep-alive.
+ * @ctlr_ka_time: time of next controller keep-alive.
+ * @timer: timer struct used for all delayed events.
+ * @link_work: &work_struct for doing FCF selection.
+ * @recv_work: &work_struct for receiving FIP frames.
+ * @fip_recv_list: list of received FIP frames.
+ * @user_mfs: configured maximum FC frame size, including FC header.
+ * @flogi_oxid: exchange ID of most recent fabric login.
+ * @flogi_count: number of FLOGI attempts in AUTO mode.
+ * @link: current link status for libfc.
+ * @last_link: last link state reported to libfc.
+ * @map_dest: use the FC_MAP mode for destination MAC addresses.
+ * @dest_addr: MAC address of the selected FC forwarder.
+ * @ctl_src_addr: the native MAC address of our local port.
+ * @data_src_addr: the assigned MAC address for the local port after FLOGI.
+ * @send: LLD-supplied function to handle sending of FIP Ethernet frames.
+ * @update_mac: LLD-supplied function to handle changes to MAC addresses.
+ * @lock: lock protecting this structure.
+ *
+ * This structure is used by all FCoE drivers. It contains information
+ * needed by all FCoE low-level drivers (LLDs) as well as internal state
+ * for FIP, and fields shared with the LLDS.
