Can you give me a brief description of this (relatively ancient) patch? Your
original e-mail is visible here:

I'm wondering if this patch needs to be backported to older CPSW driver
snapshots (specifically, TI's 2.6.37 branch for dm81xx.) It appears to
fix a multicast bug I'm tracking down, but it's difficult to know for
sure without a good description of what problem the patch addresses. (I
don't want to commit code that fixes my hardware by accident.)

For a little more information, you can refer to my e2e.ti.com post:

I'm slowly learning about ALE filtering, but a quick reply from a
domain expert would be very helpful.

best,
Graeme
