Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Merge 'net' bug fixes into 'net-next' as we have patches that will build on top of them. This merge commit includes a change from Emil Goode (emilgoode@gmail.com) that fixes a warning that would have been introduced by this merge. Specifically it fixes the pingv6_ops method ipv6_chk_addr() to add a "const" to the "struct net_device *dev" argument and likewise update the dummy_ipv6_chk_addr() declaration. Signed-off-by: David S. Miller <davem@davemloft.net>
