From 989133bf7ff3fe6ebcb9c1e7b5e13bebac175d35 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Wed, 1 Aug 2018 00:38:59 +0200 Subject: selftests: forwarding: Move lldpad waiting to lib.sh The function lldpad_wait() will be useful for a test added by a following patch. Likewise would the "sleep 5" with its extensive comment. Therefore move lldpad_wait() to lib.sh in order to allow reuse. Rename it to lldpad_app_wait_set() to recognize that what this is intended to wait on are the pending APP sets. For the sleeping, add a function lldpad_app_wait_del(). That will serve to hold the related explanatory comment (which edit for clarity), and as a token in the caller to identify the sites where this sort of waiting takes place. That will serve when/if a better way to handle this business is found. Signed-off-by: Petr Machata Reviewed-by: Ido Schimmel Signed-off-by: David S.
