fcoe_check_wait_queue() - Attempt to clear the transmit backlog : The local port whose backlog is to be cleared
This empties the wait_queue, dequeues the head of the wait_queue queue and calls fcoe_start_io() for each packet. If all skb have been transmitted it returns the qlen. If an error occurs it restores wait_queue (to try again later) and returns -1.
The wait_queue is used when the skb transmit fails. The failed skb will go in the wait_queue which will be emptied by the timer function or by the next skb transmit.
Definition at line 282 of file fcoe_transport.c.
fcoe_clean_pending_queue() - Dequeue a skb and free it : The local port to dequeue a skb on
Definition at line 254 of file fcoe_transport.c.
fcoe_ctlr_destroy() - Disable and tear down a FCoE controller : The FCoE controller to tear down
This is called by FCoE drivers before freeing the &fcoe_ctlr.
The receive handler will have been deleted before this to guarantee that no more recv_work will be scheduled.
The timer routine will simply return once we set FIP_ST_DISABLED. This guarantees that no further timeouts or work will be scheduled.
Definition at line 265 of file fcoe_ctlr.c.
fcoe_ctlr_els_send() - Send an ELS frame encapsulated by FIP if appropriate. : FCoE controller. : libfc fc_lport to send from : FCoE ELS frame including FC header but no FCoE headers.
Returns a non-zero error code if the frame should not be sent. Returns zero if the caller should send the frame with FCoE encapsulation.
The caller must check that the length is a multiple of 4. The SKB must have enough headroom (28 bytes) and tailroom (8 bytes). The the skb must also be an fc_frame.
This is called from the lower-level driver with spinlocks held, so we must not take a mutex here.

fcoe_ctlr_init() - Initialize the FCoE Controller instance : The FCoE controller to initialize
Definition at line 148 of file fcoe_ctlr.c.
fcoe_ctlr_link_down() - Stop a FCoE controller : The FCoE controller to be stopped
Returns non-zero if the link was up and now isn't.
Called from the LLD when the network link is not ready. There may be multiple calls while the link is down.
Definition at line 464 of file fcoe_ctlr.c.
fcoe_ctlr_link_up() - Start FCoE controller : The FCoE controller to start
Called from the LLD when the network link is ready.
Definition at line 408 of file fcoe_ctlr.c.
fcoe_ctlr_recv() - Receive a FIP packet : The FCoE controller that received the packet : The received FIP packet
This may be called from either NET_RX_SOFTIRQ or IRQ.
Definition at line 1446 of file fcoe_ctlr.c.
fcoe_ctlr_recv_flogi() - Snoop pre-FIP receipt of FLOGI response : The FCoE controller : The FC frame to snoop
Snoop potential response to FLOGI or even incoming FLOGI.
The caller has checked that we are waiting for login as indicated by fip->flogi_oxid != FC_XID_UNKNOWN.
The caller is responsible for freeing the frame. Fill in the granted_mac address.
Return non-zero if the frame should not be delivered to libfc.
Definition at line 1825 of file fcoe_ctlr.c.
fcoe_fc_crc() - Calculates the CRC for a given frame : The frame to be checksumed
This uses crc32() routine to calculate the CRC for a frame
Return: The 32 bit CRC value

Definition at line 2847 of file fcoe_ctlr.c.
fcoe_get_paged_crc_eof() - Allocate a page to be used for the trailer CRC : The packet to be transmitted : The total length of the trailer : The fcoe context
This routine allocates a page for frame trailers. The page is re-used if there is enough room left on it for the current trailer. If there isn't enough buffer left a new page is allocated for the trailer. Reference to the page from this function as well as the skbs using the page fragments ensure that the page is freed at the appropriate time.
Returns: 0 for success

fcoe_get_wwn() - Get the world wide name from LLD if it supports it : the associated net device : the output WWN : the type of WWN (WWPN or WWNN)

fcoe_libfc_config() - Sets up libfc related properties for local port : The local port to configure libfc for : The FCoE controller in use by the local port : The libfc function template : If non-zero, the FCP portion of libfc should be initialized
Returns : 0 for success

Calls fcoe_check_wait_queue on timeout
