rtl8139: use net/eth.h macros instead of custom macros
Eliminate the following "custom" macros since they are just duplicates of net/eth.h macros under a different name: ETHER_ADDR_LEN -> ETH_ALEN ETH_P_8021Q -> ETH_P_VLAN IP_HEADER_LENGTH -> IP_HDR_GET_LEN TCP_FLAG_FIN -> TH_FIN TCP_FLAG_PUSH -> TH_PUSH Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Jason Wang <jasowang@redhat.com> Message-id: 1438604157-29664-3-git-send-email-stefanha@redhat.com
