Subject: [PATCH V7 net-next 00/11] 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.
