bnx2x: Force fundamental reset for EEH recovery

commit da29370 upstream. EEH recovery for bnx2x based adapters is not reliable on all Power systems using the default hot reset, which can result in an unrecoverable EEH error. Forcing the use of fundamental reset during EEH recovery fixes this. Signed-off-by: Brian King <[email protected]> Signed-off-by: David S.
