 14           you want to use under Linux. If you are going to run SLIP or PPP over
 15           telephone line or null modem cable you need say Y here. Connecting
 16           two machines with parallel ports using PLIP needs this, as well as

 47           'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux.
