ENETC it a gigabit Ethernet controller found on the LS1028A board. It supports basic VLAN offloads - tag extraction, injection and hardware filtering. Inband MDIO connectivity is used for link status monitoring through the miibus interface. Fixed-link mode is also supported, which allows for operation of internal cpu to switch port. Since no admin interrupts are present in hardware, link status polling has to be used. Due to a hardware bug software reset of the NIC results in a external abort. Because of that most of the hardware initialization is done during attach. This also means that in the case of an fatal error full board reset is required. The enetc_hw.h header was imporoted from Linux. It is dual licensed.
