Both the ACL meter and the port meter have a meter unit bit that makes them
count frames instead of bytes, but the driver refuses rate_pkt_ps. Program
a packet rate in that mode. In packet mode a frame costs 128 times the
tokens a byte costs in byte mode at every token unit, as in the rate tables
of qca-ssdk adpt_hppe_policer.c, so the existing byte rate helper serves
both.
Measured on IPQ8074 at 4100 packets/s, n=3 at each of two frame sizes: an
ACL police passes 4100-4110 packets/s, and a packet-rate port police holds
its rate in the same test.
