SCTP incorrectly doubles rto ever time a Hearbeat chunk is generated. However RFC 4960 states: On an idle destination address that is allowed to heartbeat, it is recommended that a HEARTBEAT chunk is sent once per RTO of that destination address plus the protocol parameter 'HB.interval', with jittering of +/- 50% of the RTO value, and exponential backoff of the RTO if the previous HEARTBEAT is unanswered. Essentially, of if the heartbean is unacknowledged, do we double the RTO. Signed-off-by:

The sctp crc32c checksum is always generated in little endian. So, we clean up the code to treat it as little endian and remove all the __force casts. Suggested by Herbert Xu. Signed-off-by:

This is a new version of my patch, now using a module parameter instead of a sysctl, so that the option is harder to find. Please note that, once the module is loaded, it is still possible to change the value of the parameter in /sys/module/sctp/parameters/, which is useful if you want to do performance comparisons without rebooting. Computation of SCTP checksums significantly affects the performance of SCTP. For example, using two dual-Opteron 246 connected using a Gbe network, it was not possible to achieve more than ~730 Mbps, compared to 941 Mbps after disabling SCTP checksums. Unfortunately, SCTP checksum offloading in NICs is not commonly available (yet). By default, checksums are still enabled, of course. Signed-off-by:

Currently the driver uses advanced descriptors for its main functionality, but then uses legacy when testing. This patch changes this so that advanced descriptors are used throughout and all mentions of legacy descriptors are removed. Signed-off-by:

IP Checksum enable doesn't need packet split in order to function. It only requires the use of advanced descriptors which the current igb driver does. So we can enable it always without any issues. Signed-off-by:

This patch: - increases the precision of the receive/transmit interrupt coalescing register value computations by using 64bit temporaries; - adds functions to read the current hardware coalescing register values and convert them back to usecs; - exports the {get,set} {rx,tx} coal methods via the standard ethtool coalescing interface.
