Re: [PATCH V4] bridge: fix br_multicast_ipv6_rcv for paged skbs

From: Tomas Winkler <redacted>

use pskb_may_pull to access ipv6 header correctly for paged skbs
It was omitted in the bridge code leading to crash in blind
__skb_pull

since the skb is cloned undonditionally we also simplify the
the exit path

this fixes bug https://bugzilla.kernel.org/show_bug.cgi?id=25202

Looks good, applied thanks Tomas.

There are several simplifications we can make in the net-next-2.6
tree.

Most of this code just wants the query type and then optionally
the ipv6 address the operation applies to.  For such simple value
fetching, skb_header_pointer() is probably ideal compared to
all of this pskb_may_pull() business.
