pointer to the mdi_tx_if_t structure
returned by the
mdi_tx_if_init(D3mdi)
function.
q
pointer to the driver's write queue
Return values
None
Usage
This function is typically called from the driver's
open(D2mdi)
routine to enable an MDI MP-aware lock structure
that was initialized by the
mdi_tx_if_init(D3mdi)
function.
mdi_tx_if_enable( )
copies the q pointer
into the mdi_tx_if_t structure;
a non-NULL q pointer here
enables processing with this lock structure.
