BCM 57416 doesnot notify peer port PHY_DOWN

Liushuang — Fri, 10 Oct 2025 07:00:13 GMT

Shutdown NIC (10Gb 2-port Base-T BCM57416 OCP3 Adapter, mac : 0432-0105-1cf0), current state of peer port is still UP. And local port doesn't notify peer port PHY_DOWN.

Current driver and firmware is :

[root@localhost ~]# ethtool -i ens1f0np0
driver: bnxt_en
version: 5.10.0-60.18.0.50.3.hl202.x86_6
firmware-version: 222.0.138.0/pkg 222.1.68.0
expansion-rom-version:
bus-info: 0000:5f:00.0

Can we upgrade driver or firmware to solve this issue?

Thanks.

Hello @Liushuang,

Check for driver/firmware updates:

Broadcom/Marvell frequently release driver and firmware updates addressing link state and PHY notification bugs. Visit HPE or Broadcom official sites for latest bnxt_en driver and BCM57416 firmware matching your OS/kernel version. HPE’s customized drivers often include fixes beyond the vanilla Linux driver.

Upgrade path:

Firmware upgrades typically require downtime and vendor-specific tools (e.g., bnxtfwloader or vendor-supplied utilities).

Upgrading to the latest supported firmware can fix PHY state synchronization issues.

Newer bnxt_en drivers (kernel 5.15+ or newer releases) may have fixes for better PHY event propagation.

Temporary Workarounds:

Sometimes, toggling link state manually (ethtool --change), or restarting the NIC interface after shutdown can propagate the state correctly.

If using switches, check if switch firmware supports Link State Propagation or similar features.

Regards,

Thanks for your reply. The problem is that we need the firmware that is compatible with DPDK 20.08. No such infomation is provided on HPE.com. So is it a better choice to submit a case?

Looks like I wasn't able to find anything as well.

I guess it's better to go with the support ticket.
