I agree with you.  Then how about something like

   Have you looked at the patch? RTL8019 is easily detectable at
runtime, so the limitation is easily enforcable w/o extra Kconfig
option, I think

Well, I meant something like:

#elif defined(CONFIG_NE2000_RTL8019_BYTEMODE)
#  define DCR_VAL 0x48
#  define DCR_VAL 0x49

to avoid changing #elif line every time when we want to support a new
board with byte-mode RTL8019AS.  Of course, calculating DCR_VAL at
runtime would be much better but I'm not sure if we can do it ...

Hm, with only 3-4 known boards so far (all Toshiba RBTX49[23][78], RBTX4925 also has the chip but I see no 2.6 support for this board), I doubt that it's worth the effort. And the option sounds a bit "too specific", IMO. :-)

Especially given the fact that it can't be attributed to RTL8019 only. Historically, there was CONFIG_NE2000_8BIT option but it's been eliminated long ago. Maybe it's worth reviving it indeed...
