net: vrf: Add support for sends to local broadcast address
Sukumar reported that sends to the local broadcast address (255.255.255.255) are broken. Check for the address in vrf driver and do not redirect to the VRF device - similar to multicast packets. With this change sockets can use SO_BINDTODEVICE to specify an egress interface and receive responses. Note: the egress interface can not be a VRF device but needs to be the enslaved device. https://bugzilla.kernel.org/show_bug.cgi?id=198521 Reported-by: Sukumar Gopalakrishnan <sukumarg1973@gmail.com> Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.
