	After commit4cdeeee925("net: udp: prefer listeners bound to an address"), UDP-Lite only works when specifying a local address for the sockets. This is related to the problem addressed in the commit719f835853("udp: add rehash on connect()"). Moreover, __udp4_lib_lookup() now looks for a socket immediately in the secondary hash table. The issue was found with LTP/network tests (UDP-Lite test-cases).
