pfSense

Summary:
When using the new if_pppoe kernel module in pfSense CE 2.8.1 with a Broadcom NIC (bce driver), a PPPoE-related boot error consistently appears:

"pppoe0: wrong interface, not accepting host unique"

Despite the error, the connection still comes up and internet access works. However, the presence of this error suggests a potential driver or interface mismatch during PPPoE initialization.

System:

- pfSense CE 2.8.1-RELEASE (amd64) - built on Fri Oct 24 16:53:00 BST 2025 - FreeBSD 15.0-CURRENT
    - Dell R210 II with onboard Broadcom NIC (bce0 & bce1)
    - WAN via PPPoE (BT Openreach)
    - Using new if_pppoe module (not legacy)

Steps to Reproduce:

1. Assign WAN PPPoE connection to Broadcom NIC (bce).
2. Enable new if_pppoe module (System > Advanced > Networking).
3. Reboot the system.
4. Observe console during boot.

Observed Behavior:

- Boot log shows:
      pppoe0: wrong interface, not accepting host unique
    - Connection still establishes successfully.

Expected Behavior:
PPPoE session should initialize cleanly with no boot errors.

Workaround:
Disabled hardware checksum offloading

Additional Notes:

- Error does not appear when using the legacy PPPoE driver.
    - Does not appear to affect Intel NICs.
    - Unclear if there are hidden side effects from this condition, but the error is consistent and should be addressed to ensure reliability.
