Description

The dblk STRUIOP_IP flag was introduced in 1994 as a consolidation private interface to speed up FDDI processing.

It is not used anywhere in illumos-gate, it is consolidation private, and from the information available, appears to only work with Synchronous STREAMS compatible drivers, and it makes the ip_cksum() source an largely unreadable complicated mess. Removing the support allows for a substantial simplification of the function.
