Thanks, I'll give this a shot.


Great.

Max, I'm not having much luck rebuilding with this code change, to be honest building the kernel from source is not something I'm used to doing.  You mentioned other workarounds may exist, are there any that don't involve rebuilding from the kernel source?

other WA is to install MLNX_OFED package.
if this option is good for you so please send me an email.


Thanks!
