Jacob Keller9229e992017-02-06 14:38:47 -0800[diff] [blame]3293 * Ensures that a given ethtool_rx_flow_spec has a valid mask. Some support
3294 * for partial matches exists with a few limitations. First, hardware only
3295 * supports masking by word boundary (2 bytes) and not per individual bit.
3296 * Second, hardware is limited to using one mask for a flow type and cannot
3297 * use a separate mask for each filter.
3298 *
3299 * To support these limitations, if we already have a configured filter for
3300 * the specified type, this function enforces that new filters of the type
3301 * match the configured input set. Otherwise, if we do not have a filter of
3302 * the specified type, we allow the input set to be updated to match the
3303 * desired filter.
3304 *
3305 * To help ensure that administrators understand why filters weren't displayed
3306 * as supported, we print a diagnostic message displaying how the input set
3307 * would change and warning to delete the preexisting filters if required.
3308 *
3309 * Returns 0 on successful input set match, and a negative return code on
3310 * failure.
