From 7e9743aef924093c9c25bdf445637434c190d31a Mon Sep 17 00:00:00 2001 From: John Lo Date: Sat, 23 Sep 2017 08:59:58 -0400 Subject: Fix sending GARP/NA on Bonded Interface Active/Backup Link Up/Down For bonded interface in Active/Backup mode (mode 1), we need to send a GARP/NA packet, if IP address is present, on slave link state change to up or down to help with route convergence. The callback from DPDK happens in a separate thread so we need to make sure RPC call is used to signal the send_garp_na process in the main thread. Also need to fix DPDK polling so the slave links are not polled.
