Explicitly pass -6 to netcat when the test is using IPv6 to prevent
failures.
Also make sure to pass "-N" to netcat to close the socket after EOF on
the client side, otherwise we would always hit the timeout and the test
would fail.
Without this fix applied:
TEST: GREv6/v4 - copy file w/ TSO [FAIL]
TEST: GREv6/v4 - copy file w/ GSO [FAIL]
TEST: GREv6/v6 - copy file w/ TSO [FAIL]
TEST: GREv6/v6 - copy file w/ GSO [FAIL]
With this fix applied:
TEST: GREv6/v4 - copy file w/ TSO [ OK ]
TEST: GREv6/v4 - copy file w/ GSO [ OK ]
TEST: GREv6/v6 - copy file w/ TSO [ OK ]
TEST: GREv6/v6 - copy file w/ GSO [ OK ]
