Subject: [PATCH 2/4] Move execute_set_action to lib/odp-util.c
Move execute_set_action from lib/dpif-netedev.c to lib/odp-util.c
This is in preparation for using execute_set_action()
in lib/odp-util.c to handle recirculation/
Signed-off-by: Simon Horman <horms@...ge.net.au>
---
packet.c might be a better place for execute_set_action()
but I'm unsure if accessing struct ovs_key_ethernet would
lead to a layering violation.
This patch depends on the patch "Add packet recirculation"
v5
* No change
rfc4
* make use of skb_mark
rfc2 - rfc3
* omitted
rfc1
* Initial post
