From 7893b2491a2d5f716540ac5643d78d37a7f6628b Mon Sep 17 00:00:00 2001 From: Moni Shoua Date: Sat, 17 May 2008 21:10:12 -0700 Subject: bonding: Send more than one gratuitous ARP when slave takes over With IPoIB, reception of gratuitous ARP by neighboring hosts is essential for a successful change of slaves in case of failure. Otherwise, they won't learn about the HW address change and need to wait a long time until the neighboring system gives up and sends an ARP request to learn the new HW address. This patch decreases the chance for a lost of a gratuitous ARP packet by sending it more than once. The number retries is configurable and can be set with a module param.
