net: fib_rules: Add new attribute to set protocol
For ages iproute2 has used `struct rtmsg` as the ancillary header for FIB rules and in the process set the protocol value to RTPROT_BOOT. Until ca56209a66 ("net: Allow a rule to track originating protocol") the kernel rules code ignored the protocol value sent from userspace and always returned 0 in notifications. To avoid incompatibility with existing iproute2, send the protocol as a new attribute. Fixes: cac56209a66 ("net: Allow a rule to track originating protocol") Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
