network stack rate shaping queues

network stack rate shaping queues

[Kent Dorfman]

A general question:

Do the network rate shaping queues apply to all network traffic in the
system, or just to the AF_INET address family?

What if we have other classes of network drivers (non ethernet) that
also use a BSD socket interface, but a different address family?  Are
those messages also subject to the rate shaping, or are they generally
FIFO to the driver queue?

My concern is specific  to the 4.x kernel.

If you mean Qdisc's like HTB, they apply universally to all traffic going
through it, unless of course you do your own packet filtering on top.

They are not specific to Ethernet either.

Thanks.
