void ixgbe_clear_interrupt_scheme

(

struct ixgbe_adapter *

adapter

)

ixgbe_clear_interrupt_scheme - Clear the current interrupt scheme settings : board private structure to clear interrupt scheme on

We go through and clear interrupt specific resources and reset the structure to pre-load conditions

int ixgbe_init_interrupt_scheme

(

struct ixgbe_adapter *

adapter

)

ixgbe_init_interrupt_scheme - Determine proper interrupt scheme : board private structure to initialize

We determine which interrupt scheme to use based on...

• Kernel support (MSI, MSI-X)
  • which can be user-defined (via MODULE_PARAM)
• Hardware queue count (num_*_queues)
  • defined by miscellaneous hardware support/features (RSS, etc.)
