Subject: app/testpmd: print fractional part in CPU cycles
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1920832a79ff1b1cdd567cf62390041c6b58c891;p=dpdk.git

app/testpmd: print fractional part in CPU cycles

Change printing of CPU cycles/packet to include fractional part for
accurateness.

Example:

Without patch:
CPU cycles/packet=14
(total cycles=4899533541 / total RX packets=343031966)

With patch:
CPU cycles/packet=14.28
(total cycles=4899533541 / total RX packets=343031966)
