Strange, I have that card as well.


Strange, I have many of those and they work fine and it works fine for
me.  How are you creating the vlans ?  ie. what is the syntax



em1 at pci0:1:0:1: class=0x020000 card=0x115e8086 chip=0x105e8086 rev=0x06
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'HP NC360T PCIe DP Gigabit Server Adapter (n1e5132)'
    class      = network
    subclass   = ethernet


% ifconfig | grep em1
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        vlan: 5 parent interface: em1
        vlan: 770 parent interface: em1
        vlan: 71 parent interface: em1
        vlan: 73 parent interface: em1
        vlan: 77 parent interface: em1
        vlan: 155 parent interface: em1
        vlan: 260 parent interface: em1
        vlan: 107 parent interface: em1
        vlan: 352 parent interface: em1
        vlan: 522 parent interface: em1
        vlan: 501 parent interface: em1
        vlan: 543 parent interface: em1
        vlan: 145 parent interface: em1
        vlan: 250 parent interface: em1
        vlan: 262 parent interface: em1
        vlan: 872 parent interface: em1
        vlan: 390 parent interface: em1
        vlan: 58 parent interface: em1
        vlan: 63 parent interface: em1
        vlan: 740 parent interface: em1
        vlan: 603 parent interface: em1
        vlan: 1123 parent interface: em1
        vlan: 502 parent interface: em1
        vlan: 504 parent interface: em1
        vlan: 1125 parent interface: em1
