[dpdk-dev] 82576 Error Disabling LPLU D0

Hello I'm trying to run my own app using dpdk 1.7.1 and 82576 NIC but it keeps failing. So I tried to run testpmd which also failed. Then I enabled e1000 debugs and found out that NIC initialization fails when setting LPLU D0 (code tries to read MDI Control Register which fails) This is probably

Hello We're currently testing an application based on L2FWD example. 1. The application is located on VM which has 2 VFs from 2 different PFs 2. One core simply polls both RX queues from VFs, makes simple message processing and forwards the messages to appropriate TX queue of different VF (so th
