From bcd323262a94b14b84341982b90443a76a477861 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 9 Nov 2009 07:40:17 +0000 Subject: [PATCH] ipv6: Allow inet6_dump_addr() to handle more than 64 addresses Apparently, inet6_dump_addr() is not able to handle more than 64 ipv6 addresses per device. We must break from inner loops in case skb is full, or else cursor is put at the end of list. Signed-off-by: Eric Dumazet Signed-off-by: David S.
