Hi,

This patch series introduces the Next generation RoCE driver for
Broadcom’s BCM5770X chip family, which supports 50/100/200/400/800G
link speeds. The driver is built as the bng_re.ko kernel module.

To keep the series within a reviewable size (~3.5K lines of code),
this initial submission focuses on the core infrastructure and
hardware initialization, including:

1) bng_en: Auxiliary device support
2) Auxiliary device support (probe/remove)
3) Get the required resources from bng_en
4) Firmware communication mechanism
5) Allocation of ib device
6) Basic debugfs infrastructure support
7) Get the device capability (QPs, CQs, SRQs, etc.)
8) Initialize the Hardware

Support for Verbs, User library and additional features will be
built on top of this patchset. hence, they will be introduced in
the subsequent patch series.

The bng_re driver shares the roce_hsi.h file with the bnxt_re
driver, as the bng_re driver leverages the hardware communication
protocol used by the bnxt_re driver.

Thanks,
Siva
