SUMMARY: icmp_rejectcodemask and T64U 5.1A

Dr. Blinn reports:

I checked with our networking expert team, and they report:

  Yes, setting icmp_rejectcodemask is still required in order to ignore
  ICMP redirects, nothing has changed in V5.1A in this regard. And,
  since there are no plans to change the default implementation, you
  should continue to set the mask to ignore these ICMP packet types in
  the future.

Original message follows:

We are in the process of installing some 5.1A servers, and we're wondering
if we should continue our (previously) standard practice of resetting the
rejectcodemask flag in the T64U kernel to prevent ICMP redirects. Is this
still an issue in 5.1A, or should we drop this step in the build process?
One example of this flag's use is given in the URL below:
