Hello,

We are using nginx-1.6 in a production environment for caching data
from multiple remote origins.

To improve our data distribution over the network we thought that using
IP DiffServ/ToS to traffic shape by backend would be useful.

We developed a small patch for the nginx core to mark packets. Because
the nginx workers don't seem to have CAP_NET_ADMIN privileges we are
using the TOS field instead of socket marks. This patch only marks
client packets and not upstream/backend packets.

Besides that, we added an X-Accel-ClassID header so that the
upstream/backend itself can choose the class id to use.

Do you find this an interesting feature to add to the nginx core? How
can we proceed and submit a patch?

Thanks,
Dani
