I don't see anything obvious that's wrong. I've just checked it now on 
my own system with the commit I rebased against and it's compiling ok.
I'm on F20 with 3.16. The part of the patch that adds the fuse library 
is below, so you could check to make sure it has applied ok.

diff --git a/lib/automake.mk b/lib/automake.mk
index 2acfe18..594dec4 100644
--- a/lib/automake.mk
+++ b/lib/automake.mk
@@ -346,6 +346,7 @@ lib_libopenvswitch_la_SOURCES += \
 endif
 
 if DPDK_NETDEV
+lib_libopenvswitch_la_LDFLAGS += -lfuse


After that I'm not really sure where to go. I'll try it on the head of 
master when I'm back in the office on Wednesday.
