lacp: fix regarding vm arg for vlib_time_now calls
Use thread-specific vlib_main_t *vm pointers to avoid problems with different threads accessing the same vlib_main_t data structure. This avoids assertion failure when vlib_time_now() is called with a vm corresponding to a different thread. Type: fix Signed-off-by: Elias Rudberg <elias.rudberg@bahnhof.net> Change-Id: I359596ecff86e03d57aa8d2330f77bf9a913485f
