flowprobe: fix sending L4 fields in L2 template and flows
Currently, when L2 and L4 recording is enabled on the L2 datapath, the L2 template will contain L4 fields and L2 flows will be exported with those fields always set to zero. With this fix, when L4 recording is enabled, add L4 fields to templates other than the L2 template (i.e. to the IP4, IP6, L2_IP4, and L2_IP6 templates). And export L2 flows without L4 fields. Also, cover that case in the tests. Type: fix Change-Id: Id5ed8b99af5634fb9d5c6e695203344782fdac01 Signed-off-by: Alexander Chernavin <achernavin@netgate.com>
