Hi boss,
I guess the answer is the length field doesn't include the VLAN header
length. But in some code, where they are adding a VLAN tag to an
untagged packet I saw that after adding the VLAN tag they are
incrementing the length field value also. Thats why i got confused.The
IEEE 802.3 says only about untagged packets. And in 802.1Q I couldn't
find anything answering my doubts.
Please help me yaar
Thanks in advance
