From 5944b5abd8646e8c6ac6af2b55f87dede1dae898 Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Tue, 30 Nov 2021 12:29:47 +0800 Subject: Bonding: add arp_missed_max option Currently, we use hard code number to verify if we are in the arp_interval timeslice. But some user may want to reduce/extend the verify timeslice. With the similar team option 'missed_max' the uers could change that number based on their own environment.
