That explains it. The bnx2 driver uses multiple TX queues, but
tc_dump_qdisc() only dumps the statistics from queue number 0.

Not sure whether we should sum them up or dump the statistics
from each queue (or both). Summing them up avoids userspace
visible changes when drivers are converted to multiq.
