ip route change dev tap0 192.168.7.0/24 rto_min 1ms Error: argument "1ms" is wrong: "rto_min" value is invalid get_time_rtt() checks for 's' or 'msec' and converts to milliseconds if needed. Fixes: 697ac63905 (utils: fix range checking for get_u32/get_u64 et all) Signed-off-by: Florian Westphal <fw@strlen.de> --- lib/utils.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
