when setting a flowid, set the M_FLOWID csum_flags bit too. this "fixes" TCP going over an interface with fq codel enabled. the way the codel code classifies a packet without a flowid set is to randomly assign it to a bucket. this in turn means that packets will get reordered, and tcp hates that. sthen was able to find a test case and narrow down at which time the problem appeared, helped greatly. tested by sthen@ and millert@ ok sashan@ jmatthew@ |
