Scapy - cant send vlan tagged packet

I can sent a basic packet using scapy and inspect it on the receiving PC using wireshark.
When I add a VLAN tag I cannot receive the packet or capture it in wireshark on the origination side

sendp( Ether()/IP(dst="172.16.64.49")/Raw(load="some data"))

sendp( Ether()/Dot1Q(vlan=42)/IP(dst="172.16.64.49")/Raw(load="some data"))

dst= 00:15:17:e4:55:52
src= b0:83:fe:e2:df:b7
type= n_802_1Q

prio= 0 id= 0 vlan= 42 type= IPv4

version= 4 ihl= 5 tos= 0x0 len= 29 id= 1 flags= frag= 0 ttl= 64 proto= ip chksum= 0x7c32 src= 172.16.102.92 dst= 172.16.64.49 options

load= 'some data'

The data looks as i would expect in scapy, any thoughts?

It looks like two things happened, the Switches in my network discarded the outer VLAN, this i discovered when i sent a packet with double VLAN encapsulation. only one VLAN label showed up at the receiving side.

The second issue with the local Wireshark not showing the packet sent was a wireshark filter mis-configuration

Required, but never shown
