On CN10KA B0/CN10KB, CPT scatter gather format has modified
to support multi-seg in inline IPsec. Due to this CPT requires
new firmware and doesn't work with CN10KA0/A1 firmware. To make
HW works in backward compatibility mode or works with CN10KA0/A1
firmware, a bit(T106_MODE) is introduced in HW CSR.

This patch adds devlink parameter for configuring T106_MODE.
