Subject: [RFC PATCH V2 net-next 04/11] net: hibmcge: Add interrupt supported in this module
The driver supports four interrupts: TX interrupt, RX interrupt,
mdio interrupt, and error interrupt.
Actually, the driver does not use the mdio interrupt.
Therefore, the driver does not request the mdio interrupt.
The error interrupt distinguishes different error information
by using different masks. To distinguish different errors,
the statistics count is added for each error.
To ensure the consistency of the code process, masks are added for the
TX interrupt and RX interrupt.
This patch implements interrupt request and free, and provides a
unified entry for the interrupt handler function. However,
the specific interrupt handler function of each interrupt
is not implemented currently.
