- * Packet capture routine for dlpi under SunOS 5
- *
- * Notes:
- *
- * - Apparently the DLIOCRAW ioctl() is specific to SunOS.
- *
- * - There is a bug in bufmod(7) such that setting the snapshot
- * length results in data being left of the front of the packet.

- * - It might be desirable to use pfmod(7) to filter packets in the
