-Subject: [PATCH] bridge: remove IPv6 depependency of bridge in 2.6.38+
-
-Since 2.6.38 the bridge module has a dependency to IPv6 if IPv6 is
-enabled. Since the IPv6 module isn't exactly lightweight and bridge also
-only needs a single function from IPv6, it's rather easy to create a
-common "lib" module with a RCU pointer to the actual implementation, if
-the IPv6 module is loaded (although slightly hackish).
-
-The codepath seems to be only taken when using IPv6, so there should be
-no negative side effects when IPv6 isn't loaded. I did not measure how
-big the performance impact is.
