This patch has the driver for 10Gigabit Ethernet controller in AMD SoC. This driver is written compatible to the Iflib framework. The existing driver is for the old version of hardware. The submitted driver here is for the recent versions of the hardware where the Ethernet controller is PCI-E based. Submitted by: Rajesh Kumar <rajesh1.kumar@amd.com> MFC after: 1 month Relnotes: yes Differential Revision: https://reviews.freebsd.org/D25793
