Subject: [PATCH net-next v7 6/8] bnxt_en: Remove struct bnxt access from RoCE driver

From: Hongguang Gao <hongguang.gao@broadcom.com>

Decouple RoCE driver from directly accessing L2's private bnxt
structure. Move the fields needed by RoCE driver into bnxt_en_dev.
They'll be passed to RoCE driver by bnxt_rdma_aux_device_add()
function.
