VRF_DEVICE integration plan

HI Netdev team, Greetings. We have been monitoring the vrf device approach for l3 isolation from cumulus networks and we are currently interested in validating it. We have following questions on them and hoping to get answers from you/concerned team. 1. As per the linux documentation,

smc911 vs smsc911

Hello, Does anyone can say what's the difference between smc911 and smsc911 ? On reading the first comments in each file it seems that there is overlapping between them: smc911x.c * This is a driver for SMSC's LAN911{5,6,7,8} single-chip Ethernet devices. smsc911x.c === *

Eric, please double check my merge work for net/ipv4/udp.c In net we fixed a soreuseport bug that added a hlist_nulls_add_tail_rcu() call to net/ipv4/udp.c And in net-next you converted UDP sockets away from nulls lists. Therefore I had to add a hlist_add_tail_rcu() implementation to
