src/sys/arch/xen/xen: if_xennet_xenbus.c
Log Message:
Patch from Brian Marcotte on port-xen@:
write a "feature-rx-notify" to the xenstore, which is used by recent
linux dom0 kernels. This reduce packet loss when using a NetBSD domU
on such linux dom0.
This entry is ignored by NetBSD and older linux domUs.
