Hmmm. This is very strange.
From what you've given me, tap_flow.c should include a tap_autoconf.h with HAVE_TC_FLOWER, avoiding the duplicated definition.

Just to be sure, can you compile the tap driver with V=1 and look for the following line?
  Looking for TCA_FLOWER_UNSPEC enum in linux/pkt_cls.h. Defining HAVE_TC_FLOWER.

And maybe use the following patch to be able to compare variables during standard compilation:

diff --git a/drivers/net/tap/Makefile b/drivers/net/tap/Makefile
index c42a680555e9..740d77ed66b9 100644
--- a/drivers/net/tap/Makefile
+++ b/drivers/net/tap/Makefile
@@ -70,6 +70,8 @@ export AUTO_CONFIG_CFLAGS = -Wno-error
 
 ifndef V
 AUTOCONF_OUTPUT := >/dev/null
+else
+$(info tap_autoconf CC=$(CC) CFLAGS=$(CFLAGS) CPPFLAGS=$(CPPFLAGS) EXTRA_CFLAGS=$(EXTRA_CFLAGS) EXTRA_CPPFLAGS=$(EXTRA_CPPFLAGS))
 endif
 
 tap_autoconf.h.new: FORCE


Prior to rebuilding, please make sure the tap_autoconf.h are removed from build/build/drivers/net/tap/.

Thank you.

Best regards,
Pascal
