Where does vlan tag get added to the transmitted Ethernet packet?
When sending a packet of data using sendto() through a vlan, the received packet has vlan tag attached at the end of the
MAC header and before the IP header. Where does the tag get added to the transmitted packet? Is it in the socket
library? io-pkt? network driver? or somewhere else?
I am getting dual vlan tag at the receive node (please see the packet data below), and I am trying to figure out why I
am getting double vlan tags.
0x0000: 0100 5E28 1114 0018 4405 050A 8100 0000
0x0010: 8100 044A 0800 4500 0050 BC4F 0000 0100
Thanks for any help...
(I am using e1000 driver with 82576)
