[dpdk-dev] Queries about the RED implementation

Hi, I was going through the implementation of RED in dpdk. I wanted to clarify some doubts about the implementation. First, In RED Paper the Pmax used, how is this related to InvMaxp in dpdk, why inverse? Secondly, the minth and maxth are constant values in RED paper, but in the dpdk implementatio

[dpdk-dev] link state change not consistent (Flaps/stays DOWN/UP for ever)

Hi All, With DPDK Stable 17.05 branch, we are seeing an issue with the link state of 10G ports on Broadwell. Link status of one of the ports keeps flapping at regular intervals, typically starts after few seconds after the link appeared to settle down. Other behaviors include not honoring a link

Re: [dpdk-dev] link state change not consistent (Flaps/stays DOWN/UP for ever)

;port stop 1;port start 1;port start 2; port stop 2; port start 3;port stop 3 1. Repeat step 2, 3 -5 times and app gets into fault state and never recovers (One of the 10G ports, goes into "DOWN" state and never comes UP again". Thanks -Avinash From: Yeddula, Avinash Sent: Tue

[dpdk-dev] 4 Traffic classes per Pipe limitation

(and pipes) comes from the number of bits available. Since the QoS code overloads the 32 bit RSS field in the mbuf there isn't enough bits to a lot.
