From d1f8297a96b0d70f17704296a6666468f2087ce6 Mon Sep 17 00:00:00 2001 From: Sascha Hlusiak Date: Sat, 26 Sep 2009 20:28:07 -0700 Subject: Revert "sit: stateless autoconf for isatap" This reverts commit 645069299a1c7358cf7330afe293f07552f11a5d. While the code does not actually break anything, it does not completely follow RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better implemented in userspace. The kernel should not send RS packages for ISATAP at all. Signed-off-by: Sascha Hlusiak Acked-by: Fred L. Templin Signed-off-by: David S.

Fix this by special-casing cfg80211-based devices, all of which are required to have an ieee80211_ptr, in the sysfs code, and also using get_wireless_stats() to have the same values reported as in procfs.
