Author: mizhka Date: Thu Nov 17 07:33:37 2016 New Revision: 308744 URL: https://svnweb.freebsd.org/changeset/base/308744 Log: [etherswitch] add infineon adm6996fc support on etherswitch This is Infineon ADM6996FC/M/MX driver code on etherswitch framework. Support PORT and DOT1Q VLAN. This code suppose ADM6996FC SDC/SDIO connect to SOC network interface MDC/MDIO. This code tested on Netgear WGR614Cv7.
