I don't think that Stephen is saying that you should hard-code the
forwarding delay as zero (i.e. to remove the delay from the kernel
completely), but rather use brctl to set the forwarding delay to zero on
bridge instances in which you're not using STP.

I don't think that Stephen is saying that you should hard-code the
forwarding delay as zero (i.e. to remove the delay from the kernel
completely), but rather use brctl to set the forwarding delay to zero on
bridge instances in which you're not using STP.
