void efx_fast_push_rx_descriptors

(

struct efx_rx_queue *

rx_queue

)

efx_fast_push_rx_descriptors - push new RX descriptors quickly : RX descriptor queue

This will aim to fill the RX descriptor queue up to ->. If there is insufficient atomic memory to do so, a slow fill will be scheduled.

The caller must provide serialisation (none is used here). In practise, this means this function must run from the NAPI handler, or be called when NAPI is disabled.

efx_filter_get_filter_safe - retrieve a filter by ID, carefully : NIC from which to remove the filter : Priority of filter, as passed to : ID of filter, as returned by : Buffer in which to store filter specification

This function will range-check , so it is safe to call with a value passed from userland.

efx_filter_insert_filter - add or replace a filter : NIC in which to insert the filter : Specification for the filter : Flag for whether the specified filter may replace a filter with an identical match expression and equal or lower priority

On success, return the filter ID. On failure, return a negative error code.
