2.6.39-stable review patch. If anyone has any objections, please let us know.
------------------ From: Eric Dumazet <[email protected]> [ Upstream commit 9aa3c94ce59066f545521033007abb6441706068 ] Knut Tidemann found that first packet of a multicast flow was not correctly received, and bisected the regression to commit b23dd4fe42b4 (Make output route lookup return rtable directly.) Special thanks to Knut, who provided a very nice bug report, including sample programs to demonstrate the bug.
