Subject: [PATCH] net/nfp: fix field initialization in Tx descriptor

[ upstream commit 01f65293ceb94921a35554fa7b17bc0ec1764c96 ]

TX descriptor eop_offset field is not initialized and it could
contain garbage. This patch fixes the potential problem setting
EOP as the only subfield. The other subfield, data offset, is
not used by now.

Fixes: b812daadad0d ("nfp: add Rx and Tx")
