PS: looking at the kernel side - even if it was present it wont be taken into consideration: it's defined but not used in code: snar@twix:~>grep -R RTA_SRC /usr/src/sys/netlink /usr/src/sys/netlink/route/route.h: NL_RTA_SRC = 2, /* binary, preferred source address */ /usr/src/sys/netlink/route/route.h:#define RTA_SRC NL_RTA_SRC snar@twix:~> -- You are receiving this mail because: You are the assignee for the bug.home | help
