I= =20 think the is not proper because this means that never the chip irq state fl= ag=20 is erased 2) I have a 32 bus connected sh2a D0 do smc9118 D0 and sh2a D31 do smc9118 = D31; do I need a software swap? ( I followed the schematics of rsk+ 7203 ev= a=20 board before to learn that for big endioan processors the designer needs to= =20 physically swap the bytes). Best regards and thanks a lot In data marted=EC 16 marzo 2010 12:35:45, Magnus Damm ha scritto: : > On Tue, Mar 16, 2010 at 8:25 PM, Fabio Giovagnini >=20 > wrote: > > Hi all, I build a board with smsc 9118 eth chip; Of course I'm not sure > > the hw is ok. >=20 > Not sure what is missing in your case, but if you want top optimize > your performance then this commit may be helpful: >=20 > http://git.kernel.org/?p=3Dlinux/kernel/git/torvalds/linux-2.6.git;a=3Dco= mmit;h > =A30c89ad41099f58922e0941e346e7c4371655b9 >=20 > / magnus >=20 --=20 Fabio Giovagnini Aurion s.r.l.
