bnx2x: Force fundamental reset for EEH recovery
commit da293700568ed3d96fcf062ac15d7d7c41377f11 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.
