207c478bd9Sstevel@tonic-gate * Program written with the assistance of the 3com documentation for
217c478bd9Sstevel@tonic-gate * the 3c905B-TX card, as well as with some assistance from the 3c59x
227c478bd9Sstevel@tonic-gate * driver Donald Becker wrote for the Linux kernel, and with some assistance
237c478bd9Sstevel@tonic-gate * from the remainder of the Etherboot distribution.
247c478bd9Sstevel@tonic-gate *
257c478bd9Sstevel@tonic-gate * REVISION HISTORY:
267c478bd9Sstevel@tonic-gate *
277c478bd9Sstevel@tonic-gate * v0.10 1-26-1998 GRB Initial implementation.
287c478bd9Sstevel@tonic-gate * v0.90 1-27-1998 GRB System works.
297c478bd9Sstevel@tonic-gate * v1.00pre1 2-11-1998 GRB Got prom boot issue fixed.
307c478bd9Sstevel@tonic-gate * v2.0 9-24-1999 SCS Modified for 3c905 (from 3c905b code)
317c478bd9Sstevel@tonic-gate * Re-wrote poll and transmit for
327c478bd9Sstevel@tonic-gate * better error recovery and heavy
337c478bd9Sstevel@tonic-gate * network traffic operation
347c478bd9Sstevel@tonic-gate * v2.01 5-26-2003 NN Fixed driver alignment issue which
357c478bd9Sstevel@tonic-gate * caused system lockups if driver structures
367c478bd9Sstevel@tonic-gate * not 8-byte aligned.
