Jacob Keller9229e992017-02-06 14:38:47 -0800[diff] [blame]3542 * Ensures that a given ethtool_rx_flow_spec has a valid mask. Some support
3543 * for partial matches exists with a few limitations. First, hardware only
3544 * supports masking by word boundary (2 bytes) and not per individual bit.
3545 * Second, hardware is limited to using one mask for a flow type and cannot
3546 * use a separate mask for each filter.
3547 *
3548 * To support these limitations, if we already have a configured filter for
3549 * the specified type, this function enforces that new filters of the type
3550 * match the configured input set. Otherwise, if we do not have a filter of
3551 * the specified type, we allow the input set to be updated to match the
3552 * desired filter.
3553 *
3554 * To help ensure that administrators understand why filters weren't displayed
3555 * as supported, we print a diagnostic message displaying how the input set
3556 * would change and warning to delete the preexisting filters if required.
3557 *
3558 * Returns 0 on successful input set match, and a negative return code on
3559 * failure.

3890 * Due to hardware limitations, it is not possible for two filters that match
3891 * similar criteria to be programmed at the same time. This is true for a few
3892 * reasons:
3893 *
3894 * (a) all filters matching a particular flow type must use the same input
3895 * set, that is they must match the same criteria.
3896 * (b) different flow types will never match the same packet, as the flow type
3897 * is decided by hardware before checking which rules apply.
3898 * (c) hardware has no way to distinguish which order filters apply in.
3899 *
3900 * Due to this, we can't really support using the location data to order
3901 * filters in the hardware parsing. It is technically possible for the user to
3902 * request two filters matching the same criteria but which select different
3903 * queues. In this case, rather than keep both filters in the list, we reject
3904 * the 2nd filter when the user requests adding it.
3905 *
3906 * This avoids needing to track location for programming the filter to
3907 * hardware, and ensures that we avoid some strange scenarios involving
3908 * deleting filters which match the same criteria.
