Realtek USB (AXE0) nic: No buffer space available

  • Hi all

    I setup a pfsense box with 3 nics:
    First 2 are 3com pci nics and works great.
    The internal sis 965 nic isn't seen by the system than I added a usb nic:

    axe0: vendor 0x0b95 product 0x1720, rev 2.00/0.01, addr 2
    miibus0: <mii bus="">on axe0
    rlphy0: <rtl8201l 10="" 100="" media="" interface="">on miibus0
    rlphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
    axe0: Ethernet address: 00:06:4f:0d:b5:34
    axe0: if_start running deferred for Giant

    The card works but from dmesg I can see a lot of this messages:

    axe0: read PHY failed

    and after some hours the card stops to work, from ifconfig I can see:

    axe0: flags=108c43 <up,broadcast,running,oactive,simplex,multicast,needsgiant>mtu 1500
            inet netmask 0xffffff00 broadcast
            inet6 fe80::206:4fff:fe0d:b534%axe0 prefixlen 64 scopeid 0x1
            ether 00:06:4f:0d:b5:34
            media: Ethernet autoselect (none)

    and If I try to ping something:


    PING ( 56 data bytes
    ping: sendto: No buffer space available

    rebooting the pfsense box fix the problem and all return to works normally.

    Any idea ?
