Firewall / Traffic Shaper / By Interface

(sorry for the typo)

What type of interfaces are those (driver name)?

Perhaps they were supported by the shaper on older versions but they are not supported now.

em0@pci0:0:3:0: class=0x020000 card=0x10128086 chip=0x10108086 rev=0x01 hdr=0x00
vendor = 'Intel Corporation'
device = '82546EB Gigabit Ethernet Controller (Copper)'
class = network
subclass = ethernet

on irc someone else had the same issue.

Also worth noting this is i386

Bridges and VLAN interfaces on LAN show up.
a spare interface on the same card shows up
It is just WAN interfaces and LAN that have no label / not listed.

I have the same issue. WAN is nfe0. LAN is em0.

I am also confirming this issue on 2.3.5 and now 2.3.5_p1.

We have 22 affected units and they are all using the igb driver. All are Supermicro SYS-5018A-FTN4 systems and we purchased multiple units through the pfSense® store in late 2015 and early 2016 as C2758 models.
