      samples: bpf: Convert ARP table network order fields into readable format · cf8980a3
      Gokul Sivakumar authored
      The ARP table that is dumped when the xdp_router_ipv4 process is launched
      has the IP address & MAC address in non-readable network byte order format,
      also the alignment is off when printing the table.
      
      Address HwAddress
      160000e0                1600005e0001
      ff96a8c0                ffffffffffff

      Fix this by converting the "Address" field from network byte order Hex into
      dotted decimal notation IPv4 format and "HwAddress" field from network byte
      order Hex into Colon separated Hex format. Also fix the aligntment of the
      fields in the ARP table.

      samples: bpf: Convert route table network order fields into readable format · f5c4e419
      Gokul Sivakumar authored
      The route table that is dumped when the xdp_router_ipv4 process is launched
      has the "Gateway" field in non-readable network byte order format, also the
      alignment is off when printing the table.

      Fix this by converting the "Gateway" field from network byte order Hex into
      dotted decimal notation IPv4 format and "Genmask" from CIDR notation into
      dotted decimal notation IPv4 format. Also fix the aligntment of the fields
      in the route table.
