From: Patrick McHardy <[EMAIL PROTECTED]>
The tpacket_hdr is not clean for 64 bit kernel/32 bit userspace and
is not extendable because the struct sockaddr_ll following it is
expected at a fixed offset.
Linux 2.6.27-rc supports a new t
pcap-linux: reconstruct VLAN header from PACKET_AUXDATA
From: Patrick McHardy <[EMAIL PROTECTED]>
VLAN packets sent over devices supporting VLAN tagging/stripping in
hardwaredon't have a VLAN header when they are received on packet
sockets. The VLAN TCI is available through the PAC
pcap-linux: reconstruct VLAN headers from tpacket2_hdr
From: Patrick McHardy <[EMAIL PROTECTED]>

without the VLAN tag.
The upcoming kernel version (2.6.27) will preserve the tag on RX
(its already present in
