Subject: Re: [PATCH 0/2] net: ethernet: Remove the 8390 network drivers

Cai,

a number of the 8390 drivers are still in active use on legacy 
architectures. These drivers get occasional updates (not just bugfixes, 
but support for 'new' network cards - I have a patch to add X-Surf 500 
support somewhere in the pipline).

Removing the 8390 drivers would leave most m68k legacy systems without 
networking support.

Unless there is a clear and compelling reason to do so, these drivers 
should not be removed.

Cheers,

	Michael
