Hello, I think there is a small bug in igmp.h. Since I'm not familiar with the kernel bug tracking procedures, I thought I'll leave a note on this list. In the IGMPV3_EXP macro (nbmant+nbexp) should be replaced by just nbmant. I noticed this in 2.6.18-2 cheers, dirk - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
