188 * a packet arrives.
189 * @rx_max_coalesced_frames: Maximum number of packets to receive
190 * before an RX interrupt.

193 * @rx_max_coalesced_frames_irq: Same as @rx_max_coalesced_frames,
194 * except that this value applies while an IRQ is being serviced
195 * by the host.
196 * @tx_coalesce_usecs: How many usecs to delay a TX interrupt after
197 * a packet is sent.
198 * @tx_max_coalesced_frames: Maximum number of packets to be sent
199 * before a TX interrupt.
200 * @tx_coalesce_usecs_irq: Same as @tx_coalesce_usecs, except that
201 * this value applies while an IRQ is being serviced by the host.
202 * @tx_max_coalesced_frames_irq: Same as @tx_max_coalesced_frames,
203 * except that this value applies while an IRQ is being serviced
204 * by the host.
205 * @stats_block_coalesce_usecs: How many usecs to delay in-memory
206 * statistics block updates. Some drivers do not have an
207 * in-memory statistic block, and in such cases this value is
208 * ignored. This value must not be zero.
209 * @use_adaptive_rx_coalesce: Enable adaptive RX coalescing.
210 * @use_adaptive_tx_coalesce: Enable adaptive TX coalescing.
211 * @pkt_rate_low: Threshold for low packet rate (packets per second).
212 * @rx_coalesce_usecs_low: How many usecs to delay an RX interrupt after
213 * a packet arrives, when the packet rate is below @pkt_rate_low.
214 * @rx_max_coalesced_frames_low: Maximum number of packets to be received
215 * before an RX interrupt, when the packet rate is below @pkt_rate_low.
216 * @tx_coalesce_usecs_low: How many usecs to delay a TX interrupt after
217 * a packet is sent, when the packet rate is below @pkt_rate_low.
218 * @tx_max_coalesced_frames_low: Maximum nuumber of packets to be sent before
219 * a TX interrupt, when the packet rate is below @pkt_rate_low.
220 * @pkt_rate_high: Threshold for high packet rate (packets per second).
221 * @rx_coalesce_usecs_high: How many usecs to delay an RX interrupt after
222 * a packet arrives, when the packet rate is above @pkt_rate_high.
223 * @rx_max_coalesced_frames_high: Maximum number of packets to be received
224 * before an RX interrupt, when the packet rate is above @pkt_rate_high.
225 * @tx_coalesce_usecs_high: How many usecs to delay a TX interrupt after
226 * a packet is sent, when the packet rate is above @pkt_rate_high.
227 * @tx_max_coalesced_frames_high: Maximum number of packets to be sent before
228 * a TX interrupt, when the packet rate is above @pkt_rate_high.
229 * @rate_sample_interval: How often to do adaptive coalescing packet rate
230 * sampling, measured in seconds. Must not be zero.
231 *
232 * Each pair of (usecs, max_frames) fields specifies this exit
233 * condition for interrupt coalescing:
234 * (usecs > 0 && time_since_first_completion >= usecs) ||
235 * (max_frames > 0 && completed_frames >= max_frames)
236 * It is illegal to set both usecs and max_frames to zero as this
237 * would cause interrupts to never be generated. To disable
238 * coalescing, set usecs = 0 and max_frames = 1.
239 *
240 * Some implementations ignore the value of max_frames and use the
241 * condition:
242 * time_since_first_completion >= usecs
243 * This is deprecated. Drivers for hardware that does not support
244 * counting completions should validate that max_frames == !rx_usecs.
245 *
246 * Adaptive RX/TX coalescing is an algorithm implemented by some
247 * drivers to improve latency under low packet rates and improve
248 * throughput under high packet rates. Some drivers only implement
249 * one of RX or TX adaptive coalescing. Anything not implemented by
250 * the driver causes these values to be silently ignored.
251 *
252 * When the packet rate is below @pkt_rate_high but above
253 * @pkt_rate_low (both measured in packets per second) the
254 * normal {rx,tx}_* coalescing parameters are used.

541 * %ETHTOOL_GRXCLSRLALL, %ETHTOOL_SRXCLSRLDEL or %ETHTOOL_SRXCLSRLINS

546 * @rule_locs: Array of used rule locations
547 *
548 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating
549 * the fields included in the flow hash, e.g. %RXH_IP_SRC. The following

553 * on return.

555 * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined

559 * set in @data then special location values should not be used.

562 * existing rule on entry and @fs contains the rule on return.
563 *
564 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the
565 * user buffer for @rule_locs on entry. On return, @data is the size
566 * of the rule table, @rule_cnt is the number of defined rules, and
567 * @rule_locs contains the locations of the defined rules. Drivers
568 * must use the second parameter to get_rxnfc() instead of @rule_locs.
569 *
570 * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
571 * @fs.@location either specifies the location to use or is a special

573 * @fs.@location is the actual rule location.

575 * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an
576 * existing rule on entry.

578 * A driver supporting the special location values for
579 * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
580 * location, and may remove a rule at a later location (lower
581 * priority) that matches exactly the same set of flows. The special
