Hello,
The patch enables the user to set the network device into the
promiscuous mode.
It's based on the patch http://perso.hurdfr.org/mmenal/promisc.patch.
Here is the patch.
Needed for GNU Mach 1.2
Based on the patch in http://perso.hurdfr.org/mmenal/promisc.patch
2008-07-29 Zheng Da <[EMAIL PROTECTED]>
*include/device/net_status.h: add a new marco value.
*linux/dev/glue/net.c: handle NET_FLAGS in device_get_status() and
device_set_status().
*linux/dev/net/core/dev.c: add the function dev_change_flags
to change the flags of device.
