Done. Lots of verbose output now.

Perhaps... but I have it set to once a second, which matches my GM:
PTP Domain Number : 44
Clock Class : 6
Master Clock Type : One Step
Clock Class Profile : G.8275.2
Master Delay Mechanism : End To End
Max Slaves Supported : 100
Max Static Slaves Supported : 0
Max Announce Message Rate : 1 Packet per 1 Second
Max Sync Message Rate : 32 Packets per Second
Max Delay Response Message Rate : 32 Packets per Second
Max Lease Duration : 300 sec
Announce Extension TLV : N/A
The BMC messages do settle down after a while. I commented out one of the GMs
and it seems to only iterate on BMC 2 or 3 times, now.

It's being run via systemd, but:
# ps -Aef | grep phc2sys
root 5041 1 0 16:27 ? 00:00:00 /usr/local/sbin/phc2sys -w -s
em2.98
and for reference:
# ethtool -T em2.98
Time stamping parameters for em2.98:
Capabilities:
hardware-transmit (SOF_TIMESTAMPING_TX_HARDWARE)
software-transmit (SOF_TIMESTAMPING_TX_SOFTWARE)
hardware-receive (SOF_TIMESTAMPING_RX_HARDWARE)
software-receive (SOF_TIMESTAMPING_RX_SOFTWARE)
software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
hardware-raw-clock (SOF_TIMESTAMPING_RAW_HARDWARE)
PTP Hardware Clock: 1
Hardware Transmit Timestamp Modes:
off (HWTSTAMP_TX_OFF)
on (HWTSTAMP_TX_ON)
Hardware Receive Filter Modes:
none (HWTSTAMP_FILTER_NONE)
ptpv1-l4-event (HWTSTAMP_FILTER_PTP_V1_L4_EVENT)
ptpv2-l4-event (HWTSTAMP_FILTER_PTP_V2_L4_EVENT)
