rtl8139: remove duplicate net/eth.h definitions
The transmit offload features inspect Ethernet, IP, TCP, and UDP headers. Avoid redefining these net/eth.h structs. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Jason Wang <jasowang@redhat.com> Message-id: 1438604157-29664-2-git-send-email-stefanha@redhat.com
