(please cc me on any reply, thanks) i'm looking at linux-2.4.20-rc4-ac1 code (and various other 2.4.x) and i see this: ./include/net/route.h:#define IPTOS_RT_MASK (IPTOS_TOS_MASK & ~3) which causes the IPTOS_MINCOST bit (2) to be ignored even if setsockopt is used to specify it. why is this? is it a bug? the other 3 tos bits appear to work fine. thanks -dean - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
