I don't care about whether there's a generic API right now. I'd rather see
it done as a staged thing, but _not_ sysctls.

Having sysctls to add/remove entries from things is just plain evil.

I'd rather instead come up with a device specific ioctl API for this for
now w/ a userland tool for each particular chip. Then once we all get a bit
more experience doing this, a unified API can be proposed.

that makes it worse
If you want to put a device specific sysctl/ioctl set out there then have a device INDEPENDENT tool that knows how to handle the devices we have modified and when we have enough examples we can change the ioctl/sysctl interface to a generic one without changing the interface people are using in their scripts.

Hi,

I think there were many comment which says "don't use device specific
sysctls, we should have more generic interface to configure NIC filter,
like Linux's ethtool".
And I heard same idea in last BSDCan, but there's still no proposal of
"generic interface for NIC filter", I suppose.
So, honestly I haven't good idea to merge the change.
Is there any people who has good idea to handle this?

Or, just merge this patch would be fine?

Hi,

The handiest way to try flexible flow distribution is using Flow
Director.
I've confirmed that the patch posted to this list two years ago works
with netmap/ixgbe.

Thanks a lot for the link, Michio!

It seems this work is yet not committed?!?

Takuya,

I see a lot of responses/comments on proposed changes. Was anything
decided at the end of it? As far as I can tell, its still not committed
to
the tree.

Thanks,
Hiren
