[MiNT] Network Drivers

[m0n0 <ole@monochrom.net>]

Hello,

I have a few questions about writing Network driver for FreeMiNT:

1. Is it possible to call some flush cache function from XIF? I know 
there is an s_system function within the KERNINFO/KENTRY struct, and it 
can be uses like Ssystem( S_FLUSHCACHE )... , but from what I know, the 
kerninfo is only accessible for XDD/XFS/KM type of modules ( passed to 
the driver init entry point as arg ) . I want to flush cache for a range 
of memory on Coldfire board. Can anybody provide info on how to do it 
with the freemint kernel?

2. During development I see that the kernel wants to send an ethernet 
packet for ARP... (parameter hwaddr passed to output function of the 
driver). However, I would have expected that the destination MAC Address 
( hwaddr parameter, right?) is set to FF.FF.FF.FF.FF.FF - which is the 
Ethernet Broadcast address.  But the hwaddr content is different, 
something like a normal MAC address... it is not random, at least not 
during a session. I did not check after reboot.

Greets,
