[PATCH net 06/18] drivers: net: amd: Remove hplance and mvme147

[Andrew Lunn]

These drivers use the 7990 core with wrappers for the HP300 and
Motorola MVME147 SBC circa 1998. It is unlikely they are used with a
modern kernel.

- * 7990.c -- LANCE ethernet IC generic routines.
- * This is an attempt to separate out the bits of various ethernet
- * drivers that are common because they all use the AMD 7990 LANCE
- * (Local Area Network Controller for Ethernet) chip.
- *
- * Copyright (C) 05/1998 Peter Maydell <pmaydell@xxxxxxxxxxxxxxxxxxxxxx>
- *
- * Most of this stuff was obtained by looking at other LANCE drivers,
- * in particular a2065.[ch]. The AMD C-LANCE datasheet was also helpful.
- * NB: this was made easy by the fact that Jes Sorensen had cleaned up
- * most of a2025 and sunlance with the aim of merging them, so the
- * common code was pretty obvious.
