Hi,

Since upgrading from FreeBSD 14.1 to FreeBSD 14.2 we get random kernel panics
on multiple servers, referring to bnxt: bnxt_dcb_list_app in the panic error.
See attached screenshot.


Servers: Dell PowerEdge R6615
NIC: 540-BCOD : Broadcom 57416 Dual Port 10GbE BASE-T Adapter, OCP NIC 3.0
Firmware:
dev.bnxt.0.ver.roce_fw_name: BONO_FW
dev.bnxt.0.ver.netctrl_fw_name: KONG_FW
dev.bnxt.0.ver.mgmt_fw_name: AFW_231.0.153.0
dev.bnxt.0.ver.hwrm_fw_name: CHIMP_FW
dev.bnxt.0.ver.fw_ver: 231.0.153.0/pkg 23.11.16.22
dev.bnxt.0.ver.roce_fw: 231.0.153
dev.bnxt.0.ver.netctrl_fw: 231.0.153
dev.bnxt.0.ver.mgmt_fw: 231.0.153
dev.bnxt.0.ver.hwrm_fw: 231.0.153

Has anyone seen something similar and have any ideas how to solve it? Tried to
turn of LRO/TSO, but that didn't help.
Downgrading to 14.1 fixes the crashes.
