[PATCH V8 net-next 00/11] Add support of HIBMCGE Ethernet Driver

[Jijie Shao]

This patch set adds the support of Hisilicon BMC Gigabit Ethernet Driver.

This patch set includes basic Rx/Tx functionality. It also includes
the registration and interrupt codes.

This work provides the initial support to the HIBMCGE and
would incrementally add features or enhancements.
