Subject: [net-next, 00/10] Introducing Broadcom BNGE Ethernet Driver

Hi,

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

To keep the series within a reviewable size (~5K lines of code), this initial
submission focuses on the core infrastructure and initialization, including:
1) PCIe support (device IDs, probe/remove)
2) Devlink support
3) Firmware communication mechanism
4) Creation of network device
5) PF Resource management (rings, IRQs, etc. for netdev & aux dev)

Support for Tx/Rx datapaths, link management, ethtool/devlink operations and
additional features will be introduced in the subsequent patch series.

The bng_en driver shares the bnxt_hsi.h file with the bnxt_en driver, as the bng_en
driver leverages the hardware communication protocol used by the bnxt_en driver.

Thanks,
Vikas
