    tcp: RTT metrics scaling · c1e20f7c
    Stephen Hemminger authored
    Some of the metrics (RTT, RTTVAR and RTAX_RTO_MIN) are stored in
    kernel units (jiffies) and this leaks out through the netlink API to
    user space where the units for jiffies are unknown.
    
    This patches changes the kernel to convert to/from milliseconds. This
    changes the ABI, but milliseconds seemed like the most natural unit
    for these parameters.  Values available via syscall in
    /proc/net/rt_cache and netlink will be in milliseconds.
