Hi, Murali, > This appears to be a cut-n-paste bug as the source is based on > ip/iplink_vlan.c and should be fixed to IFLA_HSR_MAX.
You are right. The "HSR section" indeed defines IFLA_HSR_MAX in include/linux/if_link.h of iproute2 as the max attributes number. And in the top of ip/iplink_hsr.c you will find this comment, which enhances your assumption about the origin of this mistake: /* ... Based on iplink_vlan.c by Patrick McHardy <ka...@trash.net ... */ Regards, Rami Rosen
