Latest Linux kernel has supported getting PHC from bond directly. This
would help topology like VLAN over bond to get PHC natively. To achieve
this, the new hwtstamp flag is needed when passing hwtstamp_config to
kernel. Let's supply the flag first, and fall back without flag if user
runs on old kernel.
# ./ptp4l -m -i bond0.23
ptp4l[682486.650]: selected /dev/ptp2 as PTP clock
ptp4l[682486.652]: port 1 (bond0.23): INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[682486.652]: port 0 (/var/run/ptp4l): INITIALIZING to LISTENING on
INIT_COMPLETE
ptp4l[682486.652]: port 0 (/var/run/ptp4lro): INITIALIZING to LISTENING on
INIT_COMPLETE
ptp4l[682494.549]: port 1 (bond0.23): LISTENING to MASTER on
ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES
ptp4l[682494.549]: selected local clock f8bc12.fffe.13b6e0 as best master
ptp4l[682494.549]: port 1 (bond0.23): assuming the grand master role
ptp4l[682710.410]: Switched to /dev/ptp0 as PTP clock
ptp4l[682710.410]: port 1 (bond0.23): MASTER to FAULTY on FAULT_DETECTED
(FT_UNSPECIFIED)
ptp4l[682736.404]: port 1 (bond0.23): FAULTY to LISTENING on INIT_COMPLETE
ptp4l[682742.989]: port 1 (bond0.23): LISTENING to MASTER on
ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES
ptp4l[682742.989]: port 1 (bond0.23): assuming the grand master role
Change log:
v6: revert changes in clock_create() in patch 2.
v5: update patch 01 description
v4: define HWTSTAMP_FLAG_BONDED_PHC_INDEX in missing.h
remove unneeded net_tstamp header files
v3: remove ifdef in clock_create() and FD_RTNL event.
v2: remove link state PHC_INDEX_CHANGED and use TS_LABEL_CHANGED only.
Hangbin Liu (2):
ptp4l: init iface->ts_label when interface created
ptp4l: get bond phc directly if kernel support the new hwtstamp flag
