REVISION SUMMARY
  Add support for user-supplied Host-Uniq tag in Netgraph PPPoE.
  A few ISP filter PADI requests based on such tag, to force the use of their own routers.
  The custom Host-Uniq tag is passed in the NGM_PPPOE_CONNECT control message, so it can be used with FreeBSD ppp(8) without any other change.

TEST PLAN
  I've tested the three possible Host-Uniq tags (auto-generated as before, long plain string and long binary string) with my own ISP connection.

REPOSITORY
  rS FreeBSD src repository
