149 * except that this value applies while an IRQ is being serviced
150 * by the host.
151 * @tx_coalesce_usecs: How many usecs to delay a TX interrupt after
152 * a packet is sent.
153 * @tx_max_coalesced_frames: Maximum number of packets to be sent
154 * before a TX interrupt.
155 * @tx_coalesce_usecs_irq: Same as @tx_coalesce_usecs, except that
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
159 * by the host.
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.
171 * @tx_coalesce_usecs_low: How many usecs to delay a TX interrupt after
172 * a packet is sent, when the packet rate is below @pkt_rate_low.
173 * @tx_max_coalesced_frames_low: Maximum nuumber of packets to be sent before
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.
180 * @tx_coalesce_usecs_high: How many usecs to delay a TX interrupt after
181 * a packet is sent, when the packet rate is above @pkt_rate_high.
182 * @tx_max_coalesced_frames_high: Maximum number of packets to be sent before
183 * a TX 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.
186 *
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.
194 *
195 * Some implementations ignore the value of max_frames and use the
196 * condition:
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.
200 *
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.
206 *
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.

511 * rules on return. If @data is non-zero on return then it is the
512 * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
513 * driver supports any special location values. If that flag is not
514 * set in @data then special location values should not be used.

516 * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an

519 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the

521 * of the rule table, @rule_cnt is the number of defined rules, and
522 * @rule_locs contains the locations of the defined rules. Drivers
523 * must use the second parameter to get_rxnfc() instead of @rule_locs.
524 *
525 * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
526 * @fs.@location either specifies the location to use or is a special
527 * location value with %RX_CLS_LOC_SPECIAL flag set. On return,
528 * @fs.@location is the actual rule location.
529 *
530 * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an
531 * existing rule on entry.
532 *
533 * A driver supporting the special location values for
534 * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
535 * location, and may remove a rule at a later location (lower
536 * priority) that matches exactly the same set of flows. The special
537 * values are: %RX_CLS_LOC_ANY, selecting any location;
538 * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
539 * priority); and %RX_CLS_LOC_LAST, selecting the last suitable
540 * location (minimum priority). Additional special values may be
541 * defined in future and drivers must return -%EINVAL for any
542 * unrecognised value.
