142 | * statistics block updates. Some drivers do not have an | |
143 | * in-memory statistic block, and in such cases this value is | |
144 | * ignored. This value must not be zero. | |
145 | * @use_adaptive_rx_coalesce: Enable adaptive RX coalescing. | |
146 | * @use_adaptive_tx_coalesce: Enable adaptive TX coalescing. | |
147 | * @pkt_rate_low: Threshold for low packet rate (packets per second). | |

149 | * a packet arrives, when the packet rate is below @pkt_rate_low. | |
2d7c7939 BH |
150 | * @rx_max_coalesced_frames_low: Maximum number of packets to be received |

155 | * a TX interrupt, when the packet rate is below @pkt_rate_low. | |

156 | * @pkt_rate_high: Threshold for high packet rate (packets per second). |

158 | * a packet arrives, when the packet rate is above @pkt_rate_high. | |
2d7c7939 BH |
159 | * @rx_max_coalesced_frames_high: Maximum number of packets to be received |

166 | * sampling, measured in seconds. Must not be zero. | |
167 | * | |
acf42a2a BH |
168 | * Each pair of (usecs, max_frames) fields specifies this exit |
169 | * condition for interrupt coalescing: | |
170 | * (usecs > 0 && time_since_first_completion >= usecs) || | |
171 | * (max_frames > 0 && completed_frames >= max_frames) | |
172 | * It is illegal to set both usecs and max_frames to zero as this | |
173 | * would cause interrupts to never be generated. To disable | |
174 | * coalescing, set usecs = 0 and max_frames = 1. | |
5f308d19 | 175 | * |
a27fc96b BH |
176 | * Some implementations ignore the value of max_frames and use the |
177 | * condition: | |
178 | * time_since_first_completion >= usecs | |
179 | * This is deprecated. Drivers for hardware that does not support | |
180 | * counting completions should validate that max_frames == !rx_usecs. | |
181 | * | |
5f308d19 BH |
182 | * Adaptive RX/TX coalescing is an algorithm implemented by some |
183 | * drivers to improve latency under low packet rates and improve | |
184 | * throughput under high packet rates. Some drivers only implement | |
185 | * one of RX or TX adaptive coalescing. Anything not implemented by | |
186 | * the driver causes these values to be silently ignored. | |
187 | * | |
188 | * When the packet rate is below @pkt_rate_high but above | |
189 | * @pkt_rate_low (both measured in packets per second) the | |
190 | * normal {rx,tx}_* coalescing parameters are used. | |

808 | * the netdev is up. Should usually be set to ethtool_op_get_link(), | |
809 | * which uses netif_carrier_ok(). | |
e20b5b61 | 810 | * @get_eeprom: Read data from the device EEPROM. |

829 | * @get_strings: Return a set of strings that describe the requested objects | |
68f512f2 BH |
830 | * @set_phys_id: Identify the physical devices, e.g. by flashing an LED |
831 | * attached to it. The implementation may update the indicator | |
832 | * asynchronously or synchronously, but in either case it must return | |
833 | * quickly. It is initially called with the argument %ETHTOOL_ID_ACTIVE, | |
fce55922 AB |
834 | * and must either activate asynchronous updates and return zero, return |
835 | * a negative error or return a positive frequency for synchronous | |
836 | * indication (e.g. 1 for one on/off cycle per second). If it returns | |
837 | * a frequency then it will be called again at intervals with the | |
