From: Wenzhuo Lu Date: Wed, 1 Mar 2017 06:04:49 +0000 (+0800) Subject: net/ixgbe/base: disable FC for 15B0 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=dcf9ff148c0bd80da0c86dd4e39e5f34252801c3;p=dpdk.git net/ixgbe/base: disable FC for 15B0 Disable Ethernet Flow Control (FC) for device 15B0. Make sure that ixgbe_device_supports_autoneg_fc() returns false and hw->fc.disable_fc_autoneg is set to true to avoid running the fc_autoneg function for the device 15B0, as this device doesn't support this function.
