397c478bd9Sstevel@tonic-gate * The symbols that all modules and drivers must define are:
407c478bd9Sstevel@tonic-gate *
417c478bd9Sstevel@tonic-gate * INET_NAME The name of the module/driver.
427c478bd9Sstevel@tonic-gate *
437c478bd9Sstevel@tonic-gate * The symbols that all modules must define are:
447c478bd9Sstevel@tonic-gate *

467c478bd9Sstevel@tonic-gate * INET_MODDESC The one-line description for this module.

537c478bd9Sstevel@tonic-gate * INET_DEVMTFLAGS The mt-streams(9F) flags for the driver.
547c478bd9Sstevel@tonic-gate * INET_DEVMINOR The minor number of the driver (usually 0).
557c478bd9Sstevel@tonic-gate *
567c478bd9Sstevel@tonic-gate * Drivers that need to masquerade as IP should set INET_DEVMTFLAGS to
