[Linuxptp-users] v1.7 / v 1.8 differences.

[Ian T. <Ian...@pg...>]

We are running some embedded boards based on the Altera SOC with its stmicro/stmmac.

The v1.7 code runs well.

Jan  9 19:24:29 localhost user.info ptp4l: [265569.544] selected /dev/ptp0 as PTP clock
Jan  9 19:24:29 localhost user.notice ptp4l: [265569.545] port 1: INITIALIZING to LISTENING on INITIALIZE
Jan  9 19:24:29 localhost user.notice ptp4l: [265569.545] port 0: INITIALIZING to LISTENING on INITIALIZE
Jan  9 19:24:29 localhost user.notice ptp4l: [265569.668] port 1: new foreign master 000cec.fffe.0a085d-1
Jan  9 19:24:31 localhost user.notice ptp4l: [265571.668] selected best master clock 000cec.fffe.0a085d
Jan  9 19:24:31 localhost user.notice ptp4l: [265571.668] port 1: LISTENING to UNCALIBRATED on RS_SLAVE

I've just compiled v1.8 and replaced the v1.7 binary, no other changes, and it fails ....

The function that generates the failed ioctl error hasn't changed, so is this a problem with the added RTNL link code?

Any help is appreciated.
