 11           any other computer at all.
 13           You'll have to say Y if your computer contains a network card that
 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.
 49           The driver supports multiple bonding modes to allow for both high
