Subject: [PATCH net 0/3] ipv6: Fix socket connection with DSCP fib-rules.

The "flowlabel" field of struct flowi6 is used to store both the actual
flow label and the DS Field (or Traffic Class). However the .connect
handlers of datagram and TCP sockets don't set the DS Field part when
doing their route lookup. This breaks fib-rules that match on DSCP.

Guillaume Nault (3):
  ipv6: Fix datagram socket connect with DSCP.
  ipv6: Fix tcp socket connect with DSCP.
  selftests: fib_rule_tests: Test UDP and TCP connections with DSCP
    rules.
