(patch by Dave Täht) X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6c2a29524559d0eeea21142475d49511f7b83f91;p=openwrt%2Fstaging%2Fsvanheule.git base-files: enable TCP timestamps, enable sack/dsack. (patch by Dave Täht) A year of testing in the cerowrt project shows not using timestamps to be a very bad idea in nearly any TCP at speeds above a few Mbit. Lastly sack/dsack help on recovery from larger amounts of packet loss.
