|
* %ETHTOOL_ID_INACTIVE and must deactivate the indicator. Returns a |

|
* key, and/or hash function. Arguments which are set to %NULL or zero |

* @get_rxfh_context: Get the contents of the RX flow hash indirection table, |
|
* hash key, and/or hash function assiciated to the given rss context. |
|
* Returns a negative error code or zero. |
|
* @set_rxfh_context: Create, remove and configure RSS contexts. Allows setting |
|
* the contents of the RX flow hash indirection table, hash key, and/or |
|

* @set_tunable: Set the value of a driver / device tunable. |
|
* @get_per_queue_coalesce: Get interrupt coalescing parameters per queue. |
|
* It must check that the given queue number is valid. If neither a RX nor |

|
* queue has this number, set the inapplicable fields to ~0 and return 0. |
|
* Returns a negative error code or zero. |
|
* @set_per_queue_coalesce: Set interrupt coalescing parameters per queue. |
|
* It must check that the given queue number is valid. If neither a RX nor |

|
* |
|
* All operations are optional (i.e. the function pointer may be set |
|
