Subject: net: vrf: Add support for sends to local broadcast address

From: David Ahern <redacted>


[ Upstream commit 1e19c4d689dc1e95bafd23ef68fbc0c6b9e05180 ]

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.
