This patch set implements a common function to simply set sk_txhash to a random number instead of going through the trouble to call flow dissector. From dst_negative_advice we now reset the sk_txhash in hopes of finding a better ECMP path through the network. Changing sk_txhash affects: - IPv6 flow label and UDP source port which affect ECMP in the network - Local EMCP route selection (pending changes to use sk_txhash)
