Re: [dpdk-dev] [PATCH v1] net/i40e: set no drop for traffic class

Hi Jingjing, Yes PRTDCB_TC2PFC is used to control pfc for each TC however we have noticed other advantages of using the register. By setting the register explicitly by doing the "I40E_WRITE_REG(hw, 0x1c0980, 0xff);" it allows for packets to be temporarily stored on the NICs RX SRAM until there
