A constructor that allocates a new ARP header
[in] | opCode | ARP message type (ARP request or ARP reply) |
[in] | senderMacAddr | The sender MAC address (will be put in arphdr::senderMacAddr) |
[in] | targetMacAddr | The target MAC address (will be put in arphdr::targetMacAddr) |
[in] | senderIpAddr | The sender IP address (will be put in arphdr::senderIpAddr) |
[in] | targetIpAddr | The target IP address (will be put in arphdr::targetIpAddr) |

Calculate the following fields:

Get a pointer to the ARP header. Notice this points directly to the data, so every change will change the actual packet data

inline |
Get the sender protocol address (SPA) in the form of IPv4Address
|
inline |
Get the sender hardware address (SHA) in the form of MacAddress
|
inline |
Get the target protocol address (TPA) in the form of IPv4Address
