| help |
| If enabled, then reserve space for Ethernet header to the first |
| net_buf when sending data. The default is still to have layer 2 |
| header in a separate net_buf. In RX side the Ethernet header |
| is always part of the first net_buf. |

| conform to RFC1122 section 3.3.6. This is useful in dealing with |
| buggy devices that do not follow the RFC. |

| How many VLAN tags can be configured. If set to 0, then only |
| priority tagged VLAN frames with tag value 0 can be handled. |
| This is useful if you do not want to receive any other VLAN |
| tagged frames than tag 0. This will save some memory as the |

| Gratuitous in this case means a ARP request or reply that is not |
| normally needed according to the ARP specification but could be used |
| in some cases. A gratuitous ARP request is a ARP request packet where |
| the source and destination IP are both set to the IP of the machine |
| issuing the packet and the destination MAC is the broadcast address |
| ff:ff:ff:ff:ff:ff. Ordinarily, no reply packet will occur. |
| A gratuitous ARP reply is a reply to which no request has been made. |
