Linux 2.6.36 allows drivers to provide 64-bit statistics all architectures, but this has not yet been implemented for all drivers. If you want to get accurate statistics then you need to run a monitoring program which will poll these statistics often enough that it can detect wrap-around. With a link speed of 1 Gbit/s the byte counter can wrap around after about 35 seconds. Ben. -- Ben Hutchings Once a job is fouled up, anything done to improve it makes it worse.
