154 * before a TX interrupt.

156 * this value applies while an IRQ is being serviced by the host.
157 * @tx_max_coalesced_frames_irq: Same as @tx_max_coalesced_frames,
158 * except that this value applies while an IRQ is being serviced
160 * @stats_block_coalesce_usecs: How many usecs to delay in-memory
161 * statistics block updates. Some drivers do not have an
162 * in-memory statistic block, and in such cases this value is
163 * ignored. This value must not be zero.
164 * @use_adaptive_rx_coalesce: Enable adaptive RX coalescing.
165 * @use_adaptive_tx_coalesce: Enable adaptive TX coalescing.
166 * @pkt_rate_low: Threshold for low packet rate (packets per second).
167 * @rx_coalesce_usecs_low: How many usecs to delay an RX interrupt after
168 * a packet arrives, when the packet rate is below @pkt_rate_low.
169 * @rx_max_coalesced_frames_low: Maximum number of packets to be received
170 * before an RX interrupt, when the packet rate is below @pkt_rate_low.

174 * a TX interrupt, when the packet rate is below @pkt_rate_low.
175 * @pkt_rate_high: Threshold for high packet rate (packets per second).
176 * @rx_coalesce_usecs_high: How many usecs to delay an RX interrupt after
177 * a packet arrives, when the packet rate is above @pkt_rate_high.
178 * @rx_max_coalesced_frames_high: Maximum number of packets to be received
179 * before an RX interrupt, when the packet rate is above @pkt_rate_high.

184 * @rate_sample_interval: How often to do adaptive coalescing packet rate
185 * sampling, measured in seconds. Must not be zero.
187 * Each pair of (usecs, max_frames) fields specifies this exit
188 * condition for interrupt coalescing:
189 * (usecs > 0 && time_since_first_completion >= usecs) ||
190 * (max_frames > 0 && completed_frames >= max_frames)
191 * It is illegal to set both usecs and max_frames to zero as this
192 * would cause interrupts to never be generated. To disable
193 * coalescing, set usecs = 0 and max_frames = 1.
195 * Some implementations ignore the value of max_frames and use the
197 * time_since_first_completion >= usecs
198 * This is deprecated. Drivers for hardware that does not support
199 * counting completions should validate that max_frames == !rx_usecs.
201 * Adaptive RX/TX coalescing is an algorithm implemented by some
202 * drivers to improve latency under low packet rates and improve
203 * throughput under high packet rates. Some drivers only implement
204 * one of RX or TX adaptive coalescing. Anything not implemented by
205 * the driver causes these values to be silently ignored.
207 * When the packet rate is below @pkt_rate_high but above
208 * @pkt_rate_low (both measured in packets per second) the
209 * normal {rx,tx}_* coalescing parameters are used.

855 * indication (e.g. 1 for one on/off cycle per second). If it returns

859 * %ETHTOOL_ID_INACTIVE and must deactivate the indicator. Returns a
860 * negative error code or zero.
