Subject: ixgbe: fix PTP ethtool timestamping function

From: Jacob Keller <jacob.e.keller@intel.com>

commit 1cc92eb871d6cbb1da038b4bcd89eec3c73b9781 upstream.

This patch fixes a development issue that occurred due to invalid modes reported
in the ethtool get_ts_info function. The issue is resolved by removing
unsupported modes from the Rx supported list.
