selftests: net: add test for dst hint mechanism with directed broadcast addresses
Add a test for ensuring that the dst hint mechanism is used for
directed broadcast addresses.
This test relies on mausezahn for sending directed broadcast packets.
Additionally, a high GRO flush timeout is set to ensure that packets
will be received as lists.
The test determines if the hint mechanism was used by checking
the in_brd statistic using lnstat.
