Subject: [PATCH 16/59] amd-xgbe: Handle return code from software reset
function
References: git-fixes
Patch-mainline: v4.13-rc1
Git-commit: 42d452dc4a3674bbe53fa80f00f31f72385252dd
Currently the function that performs a software reset of the hardware
provides a return code. During driver probe check this return code and
exit with an error if the software reset fails.
