NAME
       tapset::netdev - systemtap network device probe points



DESCRIPTION
       This family of probe points is used to probe the activities of network device.  It contains the following probe points:


       netdev.receive
              Fires when data arrives on network device

              Arguments:

              dev_name
                The name of the device. e.g: eth0, ath1

              length
                The length of the receiving buffer

              protocol
                The possible values of protocol could be:
                   0800    IP
                   8100    802.1Q VLAN
                   0001    802.3
                   0002    AX.25
                   0004    802.2

                   86DD    IPv6

              truesize
                The size of the received data


       netdev.transmit
              Fires when the network device wants to transmit a buffer

              Arguments:

              dev_name
                The name of the device. e.g: eth0, ath1

              length
