LINT includes bnxt_re driver. Adjust the path in files, add missing
files and add a new BNXT_C to build (which thinly wraps OFED version
with bnxt specicif stuff).

Fixes: acd884dec99a ("RDMA/bnxt_re: Add bnxt_re RoCE driver")
(cherry picked from commit 175b2c00a6bcb0c8c1f6b76b6da9bf4879a5848e)
This patch introduces the RoCE driver for the
Broadcom NetXtreme-E 10/25/50/100/200G RoCE HCAs.
The RoCE driver is a two part driver that relies
on the bnxt_en NIC driver to operate. The changes
needed in the bnxt_en driver is included through
another patch "L2-RoCE driver communication interface"
in this set.
Presently, There is no user space support, Hence
recommendation to use the krping kernel module for
testing. User space support will be incorporated in
subsequent patch submissions.

(cherry picked from commit 35b53f8c989f62286aad075ef2e97bba358144f8)
Added support for application management interface. There are two types of commands supported:
1. Firmware IOCTLs: These ioctls are meant for firmware
consumption. Driver acts as a transport for these.
2. Driver only IOCTLs: These ioctls are meant for driver
consumption. Driver will serve these ioctls without sending them down
to firmware.
