13 | * struct i40e_stats - definition for an ethtool statistic | |
14 | * @stat_string: statistic name to display in ethtool -S output | |
15 | * @sizeof_stat: the sizeof() the stat, must be no greater than sizeof(u64) | |
16 | * @stat_offset: offsetof() the stat from a base pointer | |
17 | * | |
18 | * This structure defines a statistic to be added to the ethtool stats buffer. | |
19 | * It defines a statistic as offset from a common base pointer. Stats should | |
20 | * be defined in constant arrays using the I40E_STAT macro, with every element | |
21 | * of the array using the same _type for calculating the sizeof_stat and | |
22 | * stat_offset. | |
23 | * | |
24 | * The @sizeof_stat is expected to be sizeof(u8), sizeof(u16), sizeof(u32) or | |
25 | * sizeof(u64). Other sizes are not expected and will produce a WARN_ONCE from | |
26 | * the i40e_add_ethtool_stat() helper function. | |
27 | * | |
28 | * The @stat_string is interpreted as a format string, allowing formatted | |
29 | * values to be inserted while looping over multiple structures for a given | |
30 | * statistics array. Thus, every statistic string in an array should have the | |
31 | * same type and number of format specifiers, to be formatted by variadic | |
32 | * arguments to the i40e_add_stat_string() helper function. | |

4382 | * reasons: | |
4383 | * | |
4384 | * (a) all filters matching a particular flow type must use the same input | |
4385 | * set, that is they must match the same criteria. | |
4386 | * (b) different flow types will never match the same packet, as the flow type | |
4387 | * is decided by hardware before checking which rules apply. | |

4391 | * filters in the hardware parsing. It is technically possible for the user to | |

4393 | * queues. In this case, rather than keep both filters in the list, we reject | |
4394 | * the 2nd filter when the user requests adding it. | |
4395 | * | |
4396 | * This avoids needing to track location for programming the filter to | |
