Doh, I forgot to align the patch for RELENG_4 for differences
between RELENG_4 and HEAD. The corrected patch (tested) is at
the same location. Some random statistics:
On an example (high, constant) TX load, I get the following data:
5.2 -polling 5.2 +polling 4.9 -polling 4.9 +polling
------- --------------- --------------- --------------- ------------
ste(4) 77 Kps 102 Kps 70 Kps 96 Kps
vr(4) 53 Kps 100 Kps 63 Kps 105 Kps
(Kps == kilopackets per second)
One 5.2 box was used for testing, which has both ste(4) and vr(4)
cards, and two 4.9 boxes, which have ste(4) and vr(4), respectively.
Cheers,
