Subject: hfsc: min-rate tweaks.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=79398bad9e27e387d9eed1cbead4b60d6e296d36;p=openvswitch

hfsc: min-rate tweaks.

There doesn't appear to be any reason to enforce a minimum min-rate
of 1500Bps on queues. This commit lowers the minimum to 1Bps.  A
min-rate of 0 is not allowed by hfsc in the kernel.
