-This driver supports NE2000 compatible cards (those based on DP8390,
-DP83902 and similar). It can be used with PCMCIA/CF cards provided
-that the CCR is correctly initialized.
-
-The code is based on sources from the Linux kernel (pcnet_cs.c,
-8390.h) and eCOS(if_dp83902a.c, if_dp83902a.h). Both of these 2
-wonderful world are GPL, so this is, of course, GPL.
-
-I developed and tested this driver on a custom PXA255 based system and
-with a billionton CF network card connected to the PCMCIA interface of
-the micro (have a look at README.PXA_CF for the support of this port).
-
-The options you have to specify in the config file are (with the
-value for my board as an example):
-
-#define CONFIG_DRIVER_NE2000
-
-- Enables the driver
-
-#define CONFIG_DRIVER_NE2000_BASE (0x20000000+0x300)
-
-- Address where the board is mapped
-
-
-Enjoy!
