Yuchung and Eric, thank you for your comments.
It looks like I need to think more about this patch. I was trying
to reduce the likelihood of reordering (which seems even more
important based on Eric¹s comment on pacing), but it seems like
the only way to prevent reordering is to only re-hash after

The purpose of this patch is to help balance flows across paths. A new
sysctl "tcp_retrans_txhash_prob" specifies the probability (0-100) that
the txhash (IPv6 flowlabel) will be changed after a non-RTO retransmit.
A probability is used in order to control how many flows are moved
during a congesti
