Including will not cause 660f8829a4aSRandall Stewart# logging until you set the bits.. but it 661f8829a4aSRandall Stewart# can be quite verbose.. so without this 662f8829a4aSRandall Stewart# option we don't do any of the tests for 663f8829a4aSRandall Stewart# bits and prints.. which makes the code run 664f8829a4aSRandall Stewart# faster.. if you are not debugging don't use. 665f8829a4aSRandall Stewartoptions SCTP_DEBUG 666f8829a4aSRandall Stewart# 6679c0ef6d5SOliver Fromme# This option turns off the CRC32c checksum. Basically, 6689c0ef6d5SOliver Fromme# you will not be able to talk to anyone else who 6699c0ef6d5SOliver Fromme# has not done this. Its more for experimentation to 670f8829a4aSRandall Stewart# see how much CPU the CRC32c really takes. Most new 671f8829a4aSRandall Stewart# cards for TCP support checksum offload.. so this 672f8829a4aSRandall Stewart# option gives you a "view" into what SCTP would be 673f8829a4aSRandall Stewart# like with such an offload (which only exists in 674f8829a4aSRandall Stewart# high in iSCSI boards so far). With the new 675f8829a4aSRandall Stewart# splitting 8's algorithm its not as bad as it used 676f8829a4aSRandall Stewart# to be.. but it does speed things up try only 677f8829a4aSRandall Stewart# for in a captured lab environment :-) 678f8829a4aSRandall Stewartoptions SCTP_WITH_NO_CSUM 679f8829a4aSRandall Stewart# 680cb7a4976SRandall Stewart 681f8829a4aSRandall Stewart# 682f8829a4aSRandall Stewart# All that options after that turn on specific types of 683f8829a4aSRandall Stewart# logging.
