In case of EVPN MH bond, a member port going in
protodown state due to external reason (one case being linkflap),
frr updates the state correctly but upon manually
clearing external reason trigger FRR to reinstate
protodown without any reason code.
Fix is to ensure if the protodown reason was external
and new state is to have protodown 'off' then do no reinstate
protodown.
Ticket: #3947432
Testing:
switch:#ip link show swp1
4: swp1: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 9216 qdisc
pfifo_fast master bond1 state DOWN mode DEFAULT group default qlen
1000
link/ether 1c:34:da:2c:aa:68 brd ff:ff:ff:ff:ff:ff protodown on
protodown_reason <linkflap>
switch:#ip link set swp1 protodown off protodown_reason linkflap off
switch:#ip link show swp1
4: swp1: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 9216 qdisc
pfifo_fast master bond1 state DOWN mode DEFAULT group default qlen
