Queued up via the Linux kernel’s RDMA development Git tree is “BNG_RE” as the next-generation RoCE driver from Broadcom.
This RDMA over Converged Ethernet “RoCE” driver is for Broadcom’s BCM5770X chip family. Introduced in the Linux 6.18 kerne lis the “BNG_EN” driver as the new Broadcom network driver for the BCM5770X series while for Linux 6.19 is this BNG_RE driver for the RDMA support for this new Broadcom hardware.
The Broadcom BCM5770X chip family supports 50 / 100 / 200 / 400 / 800G link speeds. This BNG_RE driver for Linux 6.19 contains all the basic hardware enablement and driver infrastructure, coming in at just around three thousand lines of C code.
Those interested in the Broadcom BNG_RE driver can see this patch series on the mailing list which in the past week was queued into RDMA.git and thus expected to be submitted for the imminent Linux 6.19 merge window.
