Detailed Description

struct vxge_hw_ring_attr - Ring open "template". : Ring completion callback. HW invokes the callback when there are new completions on that ring. In many implementations the executes in the hw interrupt context. : Ring's descriptor-initialize callback. See vxge_hw_ring_rxd_init_f{}. If not NULL, HW invokes the callback when opening the ring. : Ring's descriptor-terminate callback. If not NULL, HW invokes the callback when closing the corresponding ring. See also vxge_hw_ring_rxd_term_f{}. : User-defined "context" of that ring. Passed back to the user as one of the , , and arguments. : If specified (i.e., greater than zero): extra space reserved by HW per each receive descriptor. Can be used to store and retrieve on completion, information specific to the driver.

Ring open "template". User fills the structure with ring attributes and passes it to vxge_hw_vpath_open().
