Hi:
I am developing an ethernet PCI adapter driver for MAC OS 9.2.2
on PowerMAC G4. Now I use the DEC 21140 Driver for example
downloaded from
<
ftp://ftp.apple.com/developer/Development_Kits/OpenTransport/OT2.6/Open
_Transport_SDK_2.6.img.hqx> Open Transport SDK.
I want to get the Rx buffer for the Rx packet from the ethernet, so I
call
EnetGetRxBuffer(enet) . But it returns NULL. The functuion is called by
static void MacRxService(EnetMACPtr mac) in file EnetDEC.c.
I don't have any idea why it fails. Can you give me any advise about it?
Thanks for your help
from vivian
