We are running Redhat 6.8 on a HPE BL460c Gen 9 blade with a HP FlexFabric 20Gb 
2-port 630FLB Adapter. The NIC uses the qlogic netxtreme2 driver. There is a 
known bug with older versions of the bnx2x driver that prevents PTP from 
working. Newever releases of the kmod-netxtreme2 module resolves this. We are 
running Redhat's MRG realtime kernel that doesn't allow kmod-* kernels to load, 
so it's stuck using version 1.710.51-0 from 2014. 

While I'm working with Redhat to resolve this, I'm trying to find a way to 
force timemaster to use software timestamping instead of the hardware 
timestamping it discovers that the card supports. Any suggestions?

I've tried:

[ptp_domain 0]
time_stamping software

and 

[ptp_domain 0]
ptp4l_option time_stamping software

And 

[ptp4l.conf]
time_stamping software

and 

[ptp4l]
options -S

either the clause has no effect or it prevents the processes from starting.

Any suggestions?
