I see a phc_max_adj() call in both phc2sys and ts2phc, so I'd expect
them to handle it correctly.

OK. The issue is not related to linuxptp v3.1. Thank you for pointing
the clamp.
Is it common for phc2sys and ts2phc also ?
best regards

More details:
The type of "freq" field in "__kernel_timex" structure is fixed in
mainline kernel to "long long" type.
However "__kernel_long_t freq" in timex structure depends on machine.
Eg. for some machines it see:
include/uapi/asm-generic/posix_types.h:typedef long __kernel_long_t;
arch/spar
Hi.
A lot of PTP/PHC drivers set max_adj value quite big. Howover due to
kernel's API limit of 32bit long type value (freq) and POSIX frequency
conversion it should limited to 32767999 ppb.
It concerns the frequency limit check both for kernel, testptp and
ptp4linux servos. Simply 65.536 * 3
