166 * after a packet is sent, when the packet rate is above @pkt_rate_high.
167 * @rate_sample_interval: How often to do adaptive coalescing packet rate
168 * sampling, measured in seconds. Must not be zero.
170 * It is illegal to set both usecs and max frames to zero as this
171 * would cause interrupts to never be generated.
173 * Adaptive RX/TX coalescing is an algorithm implemented by some
174 * drivers to improve latency under low packet rates and improve
175 * throughput under high packet rates. Some drivers only implement
176 * one of RX or TX adaptive coalescing. Anything not implemented by
177 * the driver causes these values to be silently ignored.
179 * When the packet rate is below @pkt_rate_high but above
180 * @pkt_rate_low (both measured in packets per second) the
181 * normal {rx,tx}_* coalescing parameters are used.

681 * %ETHTOOL_SFEATURES changes features present in features[].valid to the
682 * values of corresponding bits in features[].requested. Bits in .requested
683 * not set in .valid or not changeable are ignored.
685 * Returns %EINVAL when .valid contains undefined or never-changeable bits
686 * or size is not equal to required number of features words (32-bit blocks).
687 * Returns >= 0 if request was completed; bits set in the value mean:
688 * %ETHTOOL_F_UNSUPPORTED - there were bits set in .valid that are not
689 * changeable (not present in %ETHTOOL_GFEATURES' features[].available)
690 * those bits were ignored.
691 * %ETHTOOL_F_WISH - some or all changes requested were recorded but the
692 * resulting state of bits masked by .valid is not equal to .requested.
693 * Probably there are other device-specific constraints on some features
694 * in the set. When %ETHTOOL_F_UNSUPPORTED is set, .valid is considered
695 * here as though ignored bits were cleared.
696 * %ETHTOOL_F_COMPAT - some or all changes requested were made by calling
697 * compatibility functions. Requested offload state cannot be properly
700 * Meaning of bits in the masks are obtained by %ETHTOOL_GSSET_INFO (number of
701 * bits in the arrays - always multiple of 32) and %ETHTOOL_GSTRINGS commands
702 * for ETH_SS_FEATURES string set. First entry in the table corresponds to least
703 * significant bit in features[0] fields. Empty strings mark undefined features.

776 * @nway_reset: Restart autonegotiation. Returns a negative error code
778 * @get_link: Report whether physical link is up. Will only be called if
779 * the netdev is up. Should usually be set to ethtool_op_get_link(),
780 * which uses netif_carrier_ok().
781 * @get_eeprom: Read data from the device EEPROM.
782 * Should fill in the magic field. Don't need to check len for zero
783 * or wraparound. Fill in the data argument with the eeprom values
784 * from offset to offset + len. Update len to the amount read.

821 * and must either activate asynchronous updates and return zero, return
822 * a negative error or return a positive frequency for synchronous
823 * indication (e.g. 1 for one on/off cycle per second). If it returns
824 * a frequency then it will be called again at intervals with the
825 * argument %ETHTOOL_ID_ON or %ETHTOOL_ID_OFF and should set the state of
826 * the indicator accordingly. Finally, it is called with the argument
827 * %ETHTOOL_ID_INACTIVE and must deactivate the indicator. Returns a
828 * negative error code or zero.
829 * @get_ethtool_stats: Return extended statistics about the device.

833 * negative error code or zero.

870 * @set_dump: Set dump specific flags to the device.
872 * All operations are optional (i.e. the function pointer may be set
873 * to %NULL) and callers must take this into account. Callers must
874 * hold the RTNL, except that for @get_drvinfo the caller may or may
877 * See the structures used by these operations for further documentation.
