So should we apply the first fix to avoid the BUG_ON() ?
Please be more specific, are you talking about splitting up
this patch in some way?
I think Eric is referring to the patch that removes the BUG_ON
in skb_segment and deals with the new mega-GRO packets.

I think that's fine for stable, but for the long term we should
fix it properly as these new meag-GRO packets still retain the
existing packet boundaries and are trivially segmentable.

If we are indeed able to do that, I doubt we would even need
the sysctl patch since the GRO performance should be vastly
superior to the non-GRO case, even for a router/bridge.

Cheers,
