Manuel Menal <mmenal@hurdfr.org> * include/device/net_status.h (NET_FLAGS): New macro. * linux/dev/glue/net.c (device_get_status): Handle NET_FLAGS case. (device_set_status): Likewise, calls dev_change_flags. * linux/dev/include/linux/netdevice.h (dev_change_flags): Declare function. * linux/dev/net/core/dev.c (dev_change_flags): Add function.
