sctp: Allow to disable SCTP checksums via module parameter
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.
