The docs[1][2] suggest it''s 1024, but tc says something else:
# tc qdisc add dev eth0 root tbf rate 1kbps latency 50ms burst 1500
# tc -s qdisc ls dev eth0
qdisc tbf 8009: rate 8000bit burst 1499b lat 48.8ms
^^^^^^^
Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
rate 0bit 0pps backlog 0b 0p requeues 0
If 1k were 1024, then I would have 8192bit above.
