[CVE-2011-0716] bridge IGMP DOS

[Andy Whitcroft]

CVE-2011-0716
	A flaw was found in the way the Linux Ethernet bridge
	implementation handled certain IGMP (Internet Group Management
	Protocol) packets. A local, unprivileged user on a system that
	has a network interface in an Ethernet bridge could use this flaw
	to crash that system.

This issue was introduced in maverick.  Fixes have hit natty and later
via mainline and stable.  Following this email is a patch for maverick
and maverick/ti-omap4, this is a simple cherry-pick from the mainline fix.

Proposing for maverick and maverick/ti-omap4.
