71 * Each channel has a single IRQ and moderation timer, started by any
72 * completion (or other event). Unless the module parameter
73 * separate_tx_channels is set, IRQs and moderation are therefore
74 * shared between RX and TX completions. In this case, when RX IRQ
75 * moderation is explicitly changed then TX IRQ moderation is
76 * automatically changed too, but otherwise we fail if the two values
77 * are requested to be different.
78 *
79 * The hardware does not support a limit on the number of completions
80 * before an IRQ, so we do not use the max_frames fields. We should
81 * report and require that max_frames == (usecs != 0), but this would
82 * invalidate existing user documentation.
83 *
84 * The hardware does not have distinct settings for interrupt
85 * moderation while the previous IRQ is being handled, so we should
86 * not use the 'irq' fields. However, an earlier developer
87 * misunderstood the meaning of the 'irq' fields and the driver did
88 * not support the standard fields. To avoid invalidating existing
89 * user documentation, we report and accept changes through either the
90 * standard or 'irq' fields. If both are changed at the same time, we
91 * prefer the standard field.
92 *
93 * We implement adaptive IRQ moderation, but use a different algorithm
94 * from that assumed in the definition of struct ethtool_coalesce.
95 * Therefore we do not use any of the adaptive moderation parameters
96 * in it.
