Subject: [PATCH] Rename ariadne2 to zorro8390
Date: Fri, 29 Aug 2003 16:50:57 +0200 [thread overview]
Message-ID: <200308291450.h7TEovZE005877@callisto.of.borg> (raw)
Rename ariadne2 to zorro8390, since this driver supports several NS8390-based
Zorro Ethernet cards. Kill all never used occurrencies of CONFIG_NE2K_ZORRO.
