modification history
--------------------
01i,09nov01,dat  Adding obsolescence warnings to outdated drivers
01h,18oct93,cd   added extra field to TX_DESC to hold associated mbuf,
		 defined EXBUS, added timer support.
01g,22sep92,rrr  added support for c++
01f,04jun92,ajm  defined appropriate regs volatile
01e,26may92,rrr  the tree shuffle
01d,03feb92,rfs  minor changes to TX_DESC, moved tunables out to driver
01c,08nov91,rfs  adapted from Ironics stuff
01b,29jul91,kjl  cleanup in preparation for release
01a,25mar91,kjl  adapted from if_ln.h 01j,05oct90,shl
