ROS 6.x export bug: eoip keepalive info missing

Hi all,

Tested on ROS 6.23 / 6.24rc10:
Not affected: ROS 5.26

The keepalive information on eoip-tunnels in export (export compact per default) is missing. See examples below, one without keepalive, one with:

[admin@MikroTik] /interface eoip> export 
/interface eoip
add mac-address=02:B5:E1:7B:8E:7A name=eoip-tunnel1 remote-address=1.1.1.1 \
    tunnel-id=1
add mac-address=02:99:34:E7:02:42 name=eoip-tunnel2 remote-address=2.2.2.2 \
    tunnel-id=2

[admin@MikroTik] /interface eoip> export verbose 
/interface eoip
add arp=enabled clamp-tcp-mss=yes disabled=no dont-fragment=no dscp=inherit \
    !keepalive l2mtu=65535 local-address=0.0.0.0 mac-address=02:B5:E1:7B:8E:7A \
    mtu=auto name=eoip-tunnel1 remote-address=1.1.1.1 tunnel-id=1
add arp=enabled clamp-tcp-mss=yes disabled=no dont-fragment=no dscp=inherit \
    keepalive=10s,10 l2mtu=65535 local-address=0.0.0.0 mac-address=\
    02:99:34:E7:02:42 mtu=auto name=eoip-tunnel2 remote-address=2.2.2.2 \
    tunnel-id=2
