I was going to push this patch, but I saw warning with clang.
ofproto_la-bundles.lo -MD -MP -MF
ofproto/.deps/ofproto_libofproto_la-bundles.Tpo -c ofproto/bundles.c
ofproto/ofproto-dpif-upcall.c:1015:61: warning: incompatible pointer
types passing 'const struct flow **' to parameter of type 'const
struct flow *'; remove & [-Wincompatible-pointer-types]
dpif_ipfix_bridge_sample(upcall->ipfix, packet, &flow,
ofproto/ofproto-dpif-ipfix.h:50:50: note: passing argument to parameter here
const struct flow *,
So can you fold attached changes that I did change along with fix for
warning and send patch.
