Symptoms:
        PHNE_10072:
        The following symptoms correspond to the descriptions in
        the defect descriptions fields for PHNE_10072:
        1. system panic when ENOBUF
        2. in 10bt mode, if cable disconnection followed by a DMA
           timeout, IFF_UP flag never gets back to "UP" (always
           "DONW") when the cable is reconnected.
        3. in 10bt mode, the cable disconnection for the cards whose
           date-code is "3396" is not recoverable when the cable is
           reconnected. driver returns EIO and need to reboot the
           system to bring the driver back up again.

        PHNE_9609:
        The following symptoms correspond to the descriptions in
        the defect descriptions fields for PHNE_9609:
        1. system panic by disconnecting cable
        2. short transmit queue hurts performance

        PHNE_6937:
        The following symptoms correspond to the descriptions in
        the defect descriptions fields for PHNE_6937:
        1. system panic
        2. "ifconfig lan# down" does not work appropriately
        3. 10 BT link doesnot detect cable reconnection
        4. when cable is severed, "Hardware State" shown by lanscan
           is set to DOWN
        5. null mac address training is supported.
        6. system deadlock/hang
        7. system hang
        8. the current block of HP MAC addresses, which start with
           0x08009, is starting to run out.

Defect Description:
        PHNE_10072:
        The following defect descriptions are for PHNE_10072:
        1. when ENOBUF retuns during transmission, we unmapped the
           bufs which have not been mapped.
        2. when we get DMA timeout, we didnot return and we screwed
           up the vgal0_if_prior_state.
        3. the checking of old MAC address (0x080009)is still in
           10bt reset(). the card with date-code "3396" have a new
           MAC address of "0x0060b0". The driver comes up after
           reboot because we initialize the driver with 100vg
           reset().

        PHNE_9609:
        The following defect descriptions are for PHNE_9606:
        1. system panic caused by miss-checking NULL pdl_head in
           label freepdls: (vgal0_ac_output) prior to deferencing
           it. Cable disconnection (ENOLINK) or ENOBUF could make
           the problem happen.
        2. driver allocated only 31 packets on transmit queue and
           it dropped packets when you send more than 31 packets
           at a time. The UDP-stream test of netperf could make the
           problem happen. For example, "netperf -t UDP_STREAM -H
           <host> -b 32 -w 1000 -l 10 -- -m 1472"

        PHNE_6937:
        The following defect descriptions are for PHNE_6937:
        1. system panic caused by callout table overflow due to a
           temporary shortage of system memory under heavy network
           traffic
        2. "ifconfig lan# down" is fixed
        3. reset the card for 10 BT to reconnect
        4. the fix makes the 100VG-AnyLAN/9000 link behavior
           consistent with other LAN/9000 links
        5. the fix is to conform to the revised hub protocol in the
           IEEE 802.12 standard
        6. a hardware defect. the fix includes a software workaround
        7. severe memory pressure
        8. the prefix of HP MAC address is checked against 0x08, if
           wrong, return error
