What were you trying to do that didn't work?

In following synce4l configuration, there are two external source, CVL-SDP22 and GNSS.

After synce4l starting, DPLL can lock to GNSS, this is correct.

After GNSS lost gps signal, synce4l can failover to CVL-SDP22.

But it will attach GNSS input_QL 0x1 to physical port enp94s0f0np0.

This is wrong, it should attach CVL-SDP22 input_QL 0xA to enp94s0f0np0.

How reproducible:

always

Steps to reproduce

1. start ptp4l on systemA as grandmaster
2. start ptp4l on systemB as client
3. start synce4l on systemB using my configuration file
4. simulate {{gnss remove antenna to trigger synce4l failover to CVL-SDP22 (see gnss_remove_antenna() }} in https://gitlab.cee.redhat.com/kernel-qe/kernel/-/blob/master/networking/dpll/common/include.sh?ref_type=heads )
5. check synce4l log, found it attach GNSS input_QL 0x1 to physical port enp94s0f0np0 wrongly.

synce4l[2736.125]: [synce4l] EEC_LOCKED/EEC_LOCKED_HO_ACQ on CVL-SDP22 of synce1

synce4l[2736.125]: [synce4l] act on EEC_LOCKED/EEC_LOCKED_HO_ACQ for enp94s0f0np0

synce4l[2736.761]: [synce4l] tx_rebuild_tlv: attached new TLV, QL=0x1 on enp94s0f0np0

synce4l[2736.761]: [synce4l] tx_rebuild_tlv: attached new extended TLV, EXT_QL=0x20 on enp94s0f0np0

Expected results

attach QL 0xA to enp94s0f0np0 after failover

Actual results

attach QL 0x1 to enp94s0f0np0 after failover
