From: Wenzhuo Lu Date: Fri, 5 Jun 2015 05:21:51 +0000 (+0800) Subject: ixgbe/base: fix init handling of X550em link down X-Git-Tag: spdx-start~9086 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b7453742a9cb6272081ecbf499b2ddb08d69f6e6;p=dpdk.git ixgbe/base: fix init handling of X550em link down This patch changes the return value for ixgbe_setup_internal_phy_t_x550em when link is down to IXGBE_SUCCESS. The driver will call ixgbe_setup_internal_phy_t_x550em when a link status change is reported. The links status change can occur on link up or link down, and if the link status change is for link down then there is no iXFI setup necessary and no error condition needs to be returned.
