Jacob Keller9229e992017-02-06 14:38:47 -0800[diff] [blame]3304 * Ensures that a given ethtool_rx_flow_spec has a valid mask. Some support
3305 * for partial matches exists with a few limitations. First, hardware only
3306 * supports masking by word boundary (2 bytes) and not per individual bit.
3307 * Second, hardware is limited to using one mask for a flow type and cannot
3308 * use a separate mask for each filter.
3309 *
3310 * To support these limitations, if we already have a configured filter for
3311 * the specified type, this function enforces that new filters of the type
3312 * match the configured input set. Otherwise, if we do not have a filter of
3313 * the specified type, we allow the input set to be updated to match the
3314 * desired filter.
3315 *
3316 * To help ensure that administrators understand why filters weren't displayed
3317 * as supported, we print a diagnostic message displaying how the input set
3318 * would change and warning to delete the preexisting filters if required.
3319 *
3320 * Returns 0 on successful input set match, and a negative return code on
3321 * failure.
