| void ixgbe_configure_fcoe | ( | struct ixgbe_adapter * | adapter | ) |
ixgbe_configure_fcoe - configures registers for fcoe at start : ptr to ixgbe adapter
This sets up FCoE related registers
Returns : none
Definition at line 612 of file ixgbe_fcoe.c.
| int ixgbe_fcoe_ddp | ( | struct ixgbe_adapter * | adapter, |
| union ixgbe_adv_rx_desc * | rx_desc, | ||
| struct sk_buff * | skb | ||
| ) |
ixgbe_fcoe_ddp - check ddp status and mark it done : ixgbe adapter : advanced rx descriptor : the skb holding the received data
This checks ddp status.
Returns : < 0 indicates an error or not a FCiE ddp, 0 indicates not passing the skb to ULD, > 0 indicates is the length of data being ddped.
Definition at line 363 of file ixgbe_fcoe.c.
| int ixgbe_fcoe_ddp_get | ( | struct net_device * | netdev, |
| u16 | xid, | ||
| struct scatterlist * | sgl, | ||
| unsigned int | sgc | ||
| ) |
ixgbe_fcoe_ddp_get - called to set up ddp context in initiator mode : the corresponding net_device : the exchange id requesting ddp : the scatter-gather list for this request : the number of scatter-gather items
This is the implementation of net_device_ops.ndo_fcoe_ddp_setup and is expected to be called from ULD, e.g., FCP layer of libfc to set up ddp for the corresponding xid of the given sglist for the corresponding I/O.
Returns : 1 for success and 0 for no ddp
Definition at line 324 of file ixgbe_fcoe.c.
| int ixgbe_fcoe_ddp_put | ( | struct net_device * | netdev, |
| u16 | xid | ||
| ) |
ixgbe_fcoe_ddp_put - free the ddp context for a given xid : the corresponding net_device : the xid that corresponding ddp will be freed
This is the implementation of net_device_ops.ndo_fcoe_ddp_done and it is expected to be called by ULD, i.e., FCP layer of libfc to release the corresponding ddp context when the I/O is done.
Returns : data length already ddp-ed in bytes
Definition at line 67 of file ixgbe_fcoe.c.
| int ixgbe_fcoe_ddp_target | ( | struct net_device * | netdev, |
| u16 | xid, | ||
| struct scatterlist * | sgl, | ||
| unsigned int | sgc | ||
| ) |
ixgbe_fcoe_ddp_target - called to set up ddp context in target mode : the corresponding net_device : the exchange id requesting ddp : the scatter-gather list for this request : the number of scatter-gather items
This is the implementation of net_device_ops.ndo_fcoe_ddp_target and is expected to be called from ULD, e.g., FCP layer of libfc to set up ddp for the corresponding xid of the given sglist for the corresponding I/O. The DDP in target mode is a write I/O request from the initiator.
Returns : 1 for success and 0 for no ddp
Definition at line 345 of file ixgbe_fcoe.c.
| int ixgbe_fcoe_disable | ( | struct net_device * | netdev | ) |
ixgbe_fcoe_disable - turn off FCoE offload feature : the corresponding netdev
Turns off FCoE offload feature in 82599.
Returns : 0 indicates success or -EINVAL on failure
Definition at line 832 of file ixgbe_fcoe.c.
| int ixgbe_fcoe_enable | ( | struct net_device * | netdev | ) |
ixgbe_fcoe_enable - turn on FCoE offload feature : the corresponding netdev
Turns on FCoE offload feature in 82599.
Returns : 0 indicates success or -EINVAL on failure
Definition at line 789 of file ixgbe_fcoe.c.
| int ixgbe_fcoe_get_hbainfo | ( | struct net_device * | netdev, |
| struct netdev_fcoe_hbainfo * | info | ||
| ) |
ixgbe_fcoe_get_hbainfo - get FCoE HBA information : ixgbe adapter : HBA information
Returns ixgbe HBA information
Returns : 0 on success
Definition at line 918 of file ixgbe_fcoe.c.
| u8 ixgbe_fcoe_get_tc | ( | struct ixgbe_adapter * | adapter | ) |
| int ixgbe_fcoe_get_wwn | ( | struct net_device * | netdev, |
| u64 * | wwn, | ||
| int | type | ||
| ) |
ixgbe_fcoe_get_wwn - get world wide name for the node or the port : ixgbe adapter : the world wide name : the type of world wide name
Returns the node or port world wide name if both the prefix and the san mac address are valid, then the wwn is formed based on the NAA-2 for IEEE Extended name identifier (ref. to T10 FC-LS Spec., Sec. 15.3).
Returns : 0 on success
Definition at line 877 of file ixgbe_fcoe.c.
| void ixgbe_free_fcoe_ddp_resources | ( | struct ixgbe_adapter * | adapter | ) |
ixgbe_free_fcoe_ddp_resources - release all fcoe ddp context resources : ixgbe adapter
Cleans up outstanding ddp context resources
Returns : none
Definition at line 673 of file ixgbe_fcoe.c.
| int ixgbe_fso | ( | struct ixgbe_ring * | tx_ring, |
| struct ixgbe_tx_buffer * | first, | ||
| u8 * | hdr_len | ||
| ) |
