Subject: multicast storms, or how do WRS SPRs work

While browsing WRS SPRs for the memPartInfoGet() bug I mentioned in another thread, I decided to see if WRS fixed the bug in the network stack that caused "multicast storms" for us. We've long since worked around that bug by disabling IP forwarding, so it was just a matter of curiosity for me. What I saw surprised me :

SPR
TITLE: Ill formed Ethernet packet (multicast Ethernet address with sub net IP address causes a multicast storm of packets with another vxWorks target
SPR #: 70788
STATUS: Fixed
DATE FIXED: May 05 2003

PRODUCT NAME: VxWorks 5.4
RELEASE STATUS: FCS
PRODUCTS AFFECTED: VxWorks

DESCRIPTION: Ill formed Ethernet packet (multicast Ethernet address with sub net IP address) causes a multicast storm of packets with another vxWorks target.
PATCHES:
DATE CREATED: Oct 08 2001



They claim to have fixed the problem! What I cannot figure out is how to get the fix! There is no link to a patch, and no mention of this SPR in any of the available patches on the WRS web site. So now I'm wondering how SPRs work. I guess that "fixed" means that the problem is understood, and the coding is done, and it will eventually find its way into a patch. Is that right? Or is there some other way to search the available patches to find which one contains this fix?
