This sysctl option is deprecated

DEPRECATED PARAMETERS         top

       The base_reachable_time and retrans_time are deprecated.  The
       sysctl command does not allow changing values of these
       parameters.  Users who insist to use deprecated kernel interfaces
       should push values to /proc file system by other means.  For
       example:

       echo 256 > /proc/sys/net/ipv6/neigh/eth0/base_reachable_time

I propose to add new option under interface

set interfaces ethernet eth1 ip[v6] base-reachable-time xxx

Hi everyone, I think I found the simplest configuration that can reproduce this problem. If we set up firewall and use this command(set system sysctl parameter net.ipv6.neigh.eth3/2) in configuration at the same time, an error message will show when startup.
This is an example

set firewall
set interfaces ethernet eth0 address 'xxx.xxx.184.32/24'
set interfaces ethernet eth0 hw-id 'xx:xx:xx:xx:xx:50'
set interfaces ethernet eth1 hw-id 'xx:xx:xx:xx:xx:ba'
set interfaces ethernet eth1 vif 2
set interfaces loopback lo
set protocols static route xxx.xxx.0.0/0 next-hop xxx.xxx.184.1
set service ntp allow-client xxxxxx 'xxx.xxx.0.0/0'
set service ntp allow-client xxxxxx '::/0'
set service ntp server xxxxx.tld
set service ntp server xxxxx.tld
set service ntp server xxxxx.tld
set service ssh
set system config-management commit-revisions '100'
set system conntrack modules ftp
set system conntrack modules h323
set system conntrack modules nfs
set system conntrack modules pptp
set system conntrack modules sip
set system conntrack modules sqlnet
set system conntrack modules tftp
set system console device ttyS0 speed '115200'
set system host-name xxxxxx
set system login user xxxxxx authentication encrypted-password xxxxxx
set system sysctl parameter net.ipv6.neigh.eth1/2.base_reachable_time_ms value '14400000'
set system syslog global facility all level 'info'
set system syslog global facility local7 level 'debug'

If delete the first line (set firewall), system will start normally without error message.
