Subject: [PATCH V10 net-next 00/10] Add support of HIBMCGE Ethernet Driver

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.
