[PATCH v1 28/30] net/i40e/base: add trace buffer reading dependencies

[Anatoly Burakov]

From: Jedrzej Jagielski <jedrzej.jagielski at intel.com>

Some driver versions need to use "Read alternate - Indirect" command
in order to get the content of trace buffer. This patch adds a couple of
defines related to that functionality.
