Basically, 6759c0ef6d5SOliver Fromme# you will not be able to talk to anyone else who 6769c0ef6d5SOliver Fromme# has not done this. Its more for experimentation to 677f8829a4aSRandall Stewart# see how much CPU the CRC32c really takes. Most new 678f8829a4aSRandall Stewart# cards for TCP support checksum offload.. so this 679f8829a4aSRandall Stewart# option gives you a "view" into what SCTP would be 680f8829a4aSRandall Stewart# like with such an offload (which only exists in 681f8829a4aSRandall Stewart# high in iSCSI boards so far). With the new 682f8829a4aSRandall Stewart# splitting 8's algorithm its not as bad as it used 683f8829a4aSRandall Stewart# to be.. but it does speed things up try only 684f8829a4aSRandall Stewart# for in a captured lab environment :-) 685f8829a4aSRandall Stewartoptions SCTP_WITH_NO_CSUM 686f8829a4aSRandall Stewart# 687cb7a4976SRandall Stewart 688f8829a4aSRandall Stewart# 689f8829a4aSRandall Stewart# All that options after that turn on specific types of 690f8829a4aSRandall Stewart# logging.
