Subject: [PATCH iproute2-next v2 1/4] devlink: Increase number of supported options

From: Ido Schimmel <idosch@...lanox.com>

Currently, the number of supported options is capped at 32 which is a
problem given we are about to add a few more and go over the limit.

Increase the limit to 64 options.
