These two should be mutually exclusive, either it's offloaded or it failed an
offload,
shouldn't be possible to have both set. I'd recommend adding some helper that
takes
care of that.
It is true that these two are mutually exclusive, but strictly speaking
there are four types of entries:
1. Entries which are not offload-able (i.e., the ports are not backed by
switchdev)
2. Entries which are being offloaded, but results yet unknown
3. Entries which are successfully offloaded, and
4. Entries which failed to be offloaded
Even if we ignore the ones which are being offloaded (type 2 is
transient), we still need two flags, otherwise we won't be able to tell
type 1 from type 4 entries.
If we need two flags anyway, having separate flags for type 3 and type 4
simplifies the logic.
Or did I misunderstood your comments?
Thanks,
Joseph
