Something broke in sending of 32 bit version of netstat around the
time 64 bit version was improved. I went back as far as 3.8.0 to recent
kernels. Could have been earlier.
The work around in user space is when you see 64 bit stats just ignore
the 32 bit version (which iproute2 does and so am i;->).

But assumming there are tools out there that know only of 32 bit
variant they will get bad stats. Here's a compile tested only patch.
Wont have to test anything for at least another day.
