 It's sip(4):
 
 sip0 at pci0 dev 14 function 0: NatSemi DP83815 10/100 Ethernet, rev 00
 sip0: interrupting at irq 10
 nsphyter0 at sip0 phy 0: DP83815 10/100 media interface, rev. 1
 sip1 at pci0 dev 15 function 0: NatSemi DP83815 10/100 Ethernet, rev 00
 sip1: interrupting at irq 9
 nsphyter1 at sip1 phy 0: DP83815 10/100 media interface, rev. 1
 sip2 at pci0 dev 16 function 0: NatSemi DP83815 10/100 Ethernet, rev 00
 sip2: interrupting at irq 11
 nsphyter2 at sip2 phy 0: DP83815 10/100 media interface, rev. 1
 
 This chips are actually supposed to be DP83816. The board is a

 I think the ability to offload the tagging process to the hardware is unrelated.
 fxp(4) doesn't offload the tagging here either, which just means it has to be
 done in software, not that it's not possible at all. Just guessing..
 
 From the vlan man page it looks like the driver (and hardware?) has to support
 oversized frames, though. But sip(4) is listed there.
 
 Best regards,
