t4vf_eth_xmit - add a packet to an Ethernet TX queue : the packet : the egress net device
Add a packet to an SGE Ethernet TX queue. Runs with softirqs disabled.
Definition at line 1072 of file sge.c.
t4vf_ethrx_handler - process an ingress ethernet packet : the response queue that received the packet : the response queue descriptor holding the RX_PKT message : the gather list of packet fragments
Process an ingress ethernet packet and deliver it to the stack.
Definition at line 1500 of file sge.c.
t4vf_free_sge_resources - free SGE resources : the adapter
Frees resources used by the SGE queue sets.
Definition at line 2342 of file sge.c.
t4vf_intr_handler - select the top-level interrupt handler : the adapter
Selects the top-level interrupt handler based on the type of interrupts (MSI-X or MSI).
Definition at line 1904 of file sge.c.
t4vf_sge_alloc_eth_txq - allocate an SGE Ethernet TX Queue : the adapter : pointer to the new txq to be filled in : the network TX queue associated with the new txq : the relative ingress queue ID to which events relating to the new txq should be directed
Definition at line 2204 of file sge.c.
t4vf_sge_alloc_rxq - allocate an SGE RX Queue : the adapter : pointer to to the new rxq's Response Queue to be filled in : if 0, a normal rspq; if 1, an asynchronous event queue : the network device associated with the new rspq : MSI-X vector index (overriden in MSI mode) : pointer to the new rxq's Free List to be filled in : the interrupt handler to invoke for the rspq
Definition at line 2033 of file sge.c.
t4vf_sge_init - initialize SGE : the adapter
Performs SGE initialization needed every time after a chip reset. We do not initialize any of the queue sets here, instead the driver top-level must request those individually. We also do not enable DMA here, that should be done after the queues have been set up.
Definition at line 2407 of file sge.c.
t4vf_sge_start - enable SGE operation : the adapter
Start tasklets and timers associated with the DMA engine.
Definition at line 2373 of file sge.c.
t4vf_sge_stop - disable SGE operation : the adapter
Stop tasklets and timers associated with the DMA engine. Note that this is effective only if measures have been taken to disable any HW events that may restart them.
