| |
OK, here's a new attempt to use the new capacity api. I also added more comments to clarify the logic. Hope this is more readable. Let me know pls.
This is on top of the patches applied by Rusty.
Note: there are now actually 2 calls to fee_old_xmit_skbs on data path so instead of passing flag '2' to the second one I thought we can just make each call free up at least 1 skb. This will work and even might be a bit faster (less branches), but in the end I discarded this idea as too fragile (relies on two calls on data path to function properly).
Warning: untested. Posting now to give people chance to comment on the API.
