My question is more about "ether_vlanencap" api. This api is supposed to insert vlantag and tranform Ethernet header into an Ethernet header with 802.1Q encapsulation and if it is unable to prepend then it will allocate a new mbuf and populate the data including the vlan tag. But it is not happening in my case, I'm passing mbuf and vlantag to this api and I get partial junk data in the packet and a corrupted m_len as well. Folks, any inputs? /Venkat On Tue, Aug 14, 2012 at 11:34 AM, Julian Elischer <julian@freebsd.org>wrote: > On 8/13/12 10:50 PM, Venkat Duvvuru wrote: > >> Hi, >> I'm trying to insert vlan tag into the packet using "ether_vlanencap" but >> the packet is getting corrupted in the mbuf and m_len is also showing a >> wrong length. >> Am I doing something wrong here?
