Subject: [dpdk-dev] [PATCH v2 11/40] net/ixgbe/base: add FC autoneg for X550em_a fiber
Date: Sun, 25 Sep 2016 16:59:48 +0800 [thread overview]
Message-ID: <1474794017-5896-12-git-send-email-xiao.w.wang@intel.com> (raw)
In-Reply-To: <1474794017-5896-1-git-send-email-xiao.w.wang@intel.com>
This patch adds a separate function for enabling FC (flow control)
auto-negotiation on X550em_a:
- rename ixgbe_fc_autoneg_x550a() to ixgbe_fc_autoneg_backplane_x550em_a().
- create ixgbe_fc_autoneg_fiber_x550em_a() specifically for fiber.
- add definitions for KRM_PCS_KX_AN_LP register and related bits.
