From 4eb61e0231be536d8116457b67b3e447bbd510dc Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Wed, 6 Feb 2008 12:05:19 -0600 Subject: cxgb3: Handle ARP completions that mark neighbors stale. When ARP completes due to a request rather than a reply the neighbor is marked NUD_STALE instead of reachable (see arp_process()). The handler for the resulting netevent needs to check also for NUD_STALE. Failure to use the arp entry can cause RDMA connection failures.
