Comment 1 for bug 1987001

I think this might be a real regression in NM.

Netplan is testing something like this (which worked nicely in the past):
    mybond:
      parameters:
        mode: 802.3ad
        ad-select: bandwidth

Therefore, /sys/class/net/mybond/bonding/ad_select should actually contain "bandwidth 1", not the default "stable 0" value.

Might be related to this?

Same for learn-interval:
    mybond:
      parameters:
        mode: balance-tlb
        mii-monitor-interval: 5
        learn-packet-interval: 15

=> /sys/class/net/mybond/bonding/lp_interval should actually be "15"
