[PATCH v4 00/11] drivers: net: xgene: Fix module crash and 1G hot-plug

[Iyappan Subramanian]

This patchset addresses the following issues,

1. Fixes the kernel crash when the driver loaded as an kernel module
	- by fixing hardware cleanups and rearrange kernel API calls

2. Hot-plug issue on the SGMII 1G interface
	- by adding a driver for MDIO management
