Subject: [net-next patch 2/2] bnx2x: Support loading cnic resources at
run-time
This patch replaces the BCM_CNIC define with a flag which can change at run-time
and which does not use the CONFIG_CNIC kconfig option.
For the PF/hypervisor driver cnic is always supported, however allocation of
cnic resources and configuration of the HW for offload mode is done only when
the cnic module registers bnx2x.
