Support modifying IPOIB CQ moderation params
This can be used to tune at run time the paramters controlling
the event (interrupt) generation rate and thus reduce the overhead
incurred by handling interrupts resulting in better throughput.
IPoIB has one CQ. As I see it, this means that you should either let the
user specify only one of rx or tx coalescing params, or make sure that
the user did not provide something that the driver can not deploy, eg
rx_usecs 12 tx_usecs 1
+static int ipoib_set_coalesce(struct net_device *dev,
+ struct ethtool_coalesce *coal)
+ coal->tx_coalesce_usecs = coal->rx_coalesce_usecs;
+ priv->etool.coalesce_usecs = coal->rx_coalesce_usecs;
+ coal->rx_max_coalesced_frames = coal->rx_max_coalesced_frames;
I guess you wanted to say here coal->tx_max_coalesced_frames =
