Hi!
I have two network interfaces - fxp and em
When i send on both interface packet with 802.1P tag, i see this tag on
fxp and don't see on em.
em:
10:41:14.849139 00:18:ba:8a:c8:c1 (oui Unknown) 00:15:b7:62:de:ec (oui
Unknown), ethertype 802.1Q (0x8100), length 118: vlan 20, p 0
fxp:

You should, I guess, with no extra steps. Perhaps the em driver
has some hardware capability, which set the priority tag to zero?
Is the vlan hardware processing enabled?
Could you post the output of ifconfig em0?

Not ALL chipsets / drivers support 802.1Q / p , maybe this is one of them?
The vlan driver handles tagging itself in software. You don't need
support by the hardware driver or the NIC itself. That said, Intel
NICs are known to work correctly and support dot1Q tags natively

I have this problem on some ethernet cards, such as:
e...@pci0:14:0:0:class=0x02 card=0x109a15d9
chip=0x109a8086 rev=0x00 hdr=0x00
vendor = 'Intel

How I can enable this processing?
ifconfig em0 vlanhwtag enables vlan processing in hw
ifconfig em0 -vlanhwtag disables vlan processing in hw
Maybe one these will work correctly without the zeroing effect.
Perhaps off topic,

I tried both variant on both NIC - fxp and em
The result doesn't change ;(
You should post to net@ and maybe the maintainer will help
you. Include pciconf.
Perhaps off topic, but why are you interested in priority
tags, since FreeBSD will silently ignore them?
