[etherlab-users] etherlab dc sync check

[Jun Yuan]

Hi Martin,

I see, that's a long time ago. You've got to know Etherlaber ealier
than I did. Things have changed since then. EC_HAVE_CYCLES would have
no effect to the DC sync in the current etherlab master v1.5.2.

I read you log file, find the "corrected with 3995858" very intesting,
since I have 0 or 400000 ususally. This must be due to EC_HAVE_CYCLES
you mentioned. Maybe you've improved that, but your changes are
missing in the current etherlab master, as EC_HAVE_CYCLES is not used
in the function ec_fsm_master_state_dc_read_offset() of the current
master fsm_master.c.

My vacation ends today, I'm not sure if I will still have time to
investigate further when I get back to work, but I would like to know
what changes you've made. Send me a copy when your souce is published.
