One use case of PACKET_FANOUT is lockless reception with one socket
per CPU. 256 is a practical limit on increasingly many machines.
Increase PACKET_FANOUT_MAX to 64K. Expand setsockopt PACKET_FANOUT to
take an extra argument max_num_members. Also explicitly define a

First patch makes the change; second patch adds unit tests.

From: Tanner Love
Add an additional control test that verifies:
-specifying two different max_num_members values fails
-specifying max_num_members > PACKET_FANOUT_MAX fails
In datapath tests, set max_num_members to PACKET_FANOUT_MAX.

getopt_long requires the last element to be filled with zeros.
Otherwise, passing an unrecognized option can cause a segfault.
