From: Magnus Karlsson <magnus.karlsson@intel.com>

Add missing exception tracing to XDP when a number of different
errors can occur. The support was only partial. Several errors
where not logged which would confuse the user quite a lot not
knowing where and why the packets disappeared.

Fixes: 21092e9ce8b1 ("ixgbevf: Add support for XDP_TX action")
