From 5f242a13e8505e0f3efd3113da6e029f6e7dfa32 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 20 Nov 2006 17:05:23 -0800 Subject: [PATCH] [SCTP]: Switch ->cmp_addr() and sctp_cmp_addr_exact() to net-endian. instances of ->cmp_addr() are fine with switching both arguments to net-endian; callers other than in sctp_cmp_addr_exact() (both as ->cmp_addr(...) and direct calls of instances) adjusted; sctp_cmp_addr_exact() switched to net-endian itself and adjustment is done in its callers Signed-off-by: Al Viro Signed-off-by: David S.
