Jacob Keller9229e992017-02-06 14:38:47 -0800[diff] [blame]3580 * Ensures that a given ethtool_rx_flow_spec has a valid mask. Some support
3581 * for partial matches exists with a few limitations. First, hardware only
3582 * supports masking by word boundary (2 bytes) and not per individual bit.
3583 * Second, hardware is limited to using one mask for a flow type and cannot
3584 * use a separate mask for each filter.
3585 *
3586 * To support these limitations, if we already have a configured filter for
3587 * the specified type, this function enforces that new filters of the type
3588 * match the configured input set. Otherwise, if we do not have a filter of
3589 * the specified type, we allow the input set to be updated to match the
3590 * desired filter.
3591 *
3592 * To help ensure that administrators understand why filters weren't displayed
3593 * as supported, we print a diagnostic message displaying how the input set
3594 * would change and warning to delete the preexisting filters if required.
3595 *
3596 * Returns 0 on successful input set match, and a negative return code on
3597 * failure.

3928 * Due to hardware limitations, it is not possible for two filters that match
3929 * similar criteria to be programmed at the same time. This is true for a few
3930 * reasons:
3931 *
3932 * (a) all filters matching a particular flow type must use the same input
3933 * set, that is they must match the same criteria.
3934 * (b) different flow types will never match the same packet, as the flow type
3935 * is decided by hardware before checking which rules apply.
3936 * (c) hardware has no way to distinguish which order filters apply in.
3937 *
3938 * Due to this, we can't really support using the location data to order
3939 * filters in the hardware parsing. It is technically possible for the user to
3940 * request two filters matching the same criteria but which select different
3941 * queues. In this case, rather than keep both filters in the list, we reject
3942 * the 2nd filter when the user requests adding it.
3943 *
3944 * This avoids needing to track location for programming the filter to
3945 * hardware, and ensures that we avoid some strange scenarios involving
3946 * deleting filters which match the same criteria.
