Hi all,
I've a custom board based on XScale IXP425. I'm in the process of porting 
rltk8139 driver on this board. Sending data are ok ( I use ethereal to 
check), but  receive fail. In receive buffer (rltk8139_eth0_rx_ring) miss a 
few data -about first 20 bytes. In this data should be a receive packet 
header, because it is zero driver doesn't receive more. Rltk8139_eth0_rx_ring 
is allocated in cached memory but all reading are done by uncached memory 
(MMU translate address). I  check up on either memory region - it's the same. 
I think this is not a  problem of memory coherency ( I use 
HAL_DCACHE_INVALIDATE macro and result is the same). It seems to me that chip 
doesn't copy all datas.
