Version 6.46 June 25, 2003
----------------------------
Fixes:
========
1. Problem:
(CQ #8086) NDIS2 DOS intermittent failed on RPL test when
using 5702 NIC. This problem traced back to v6.40 and
v5.00-v5.22. However, V5.23-v6.30 had no problem.
Cause:
The current Download Firmware (v1.9.0) combines with Tag
Status method of handling interrupt causes the RPL Protocol
waits for a response for a packet that was transmitted while
processing the receiving packet in ReceiveLookahead.
Change:
Driver queue all transmission requests during up-call to
ReceiveLookahead and returns REQUEST_QUEUED.
Impact:
Protocol that chooses to transmit while processing a
receiving packet in ReceiveLookahead such as Netbeui and RPL.
Enhancements:
=============
1. Change:
Added NoTagStatus Keyword in the PROTOCOL.INI to set Driver NOT
to utilize the default method Tag Status of handling interrupts
for none 5700 NIC.
Impact:
Helps stabilize on certain platforms when using with protocol
such as Netbeui and RPL.
Version 6.45 June 23, 2003
----------------------------
Fixes:
========
1. Problem:
(CQ #7988) OS2 APING stress test, the APPC conversation
failed. There were two issues in this problem.
Cause 1:
Index BX register was changed while Driver copying transmit
data fragments when Protocol delivered a Physical addressed
data fragment pointer.
Change 1:
Driver disables interrupts and preserves the BX register
before makes the call to OS2 Device Helpers to map the
Physical addressed data fragment pointer to a Selector.
Impact 1:
Driver's transmission logic for OS2 only.
Cause 2:
Driver miss-handled OUT_OF_RESOURCE that was returned from
the Protocol after the ReceiveLookahead call.
Change 2:
Driver will not turns Indication Off as before but simply
continue and makes no effort to re-deliver the packet.
Impact 2:
Driver's receive logic.
2. Problem:
OS2 system crashed when using IBM TCP/IP ping a large
packet size (14500 bytes).
Cause:
Protocol delivered zero byte count in the data fragment.
Driver does not copy zero byte count data fragment but
uses the number of data fragment supplies by the Protocol.
Change:
Driver calculates the number of data fragment copied
instead of use the number delivered from the Protocol.
Impact:
Driver's transmission logic.
Version 6.44 May 21, 2003
----------------------------
Fixes:
========
1. Problem:
(CQ #7839) (CQ #7840) When connected to a hub, a
momentary disconnect will cause to lose the network
connection until the driver is reloaded.
Cause:
The NIC does not generates PHY Change Interrupt after
the PHY Reset when the link is first lost.
Change:
Driver preserves and restores Auto-negotiation
advertisement register after the PHY Reset.
Impact:
None.
2. Problem:
(CQ #7843) User try to force 1G.
Cause:
Driver allows parameter to be set.
Change:
Driver will performs Auto-negotiation when LineSpeed is
set to 1000.
Impact:
None.
Version 6.43 May 11, 2003
----------------------------
Fixes:
========
1. Problem:
(CQ #7677) OS2 system crashes when uses 5700 Ax and Bx
or FullSize mode.
Cause:
Driver provided incorrect Global Descriptor Table to OS2
when called to map to its Physical area.
Change:
Driver obtains correct Global Descriptor Table to OS2
when called to map to its Physical area during
initialization.
Impact:
5700 Ax & Bx or runs in FullSize Mode in OS2.
2. Problem:
(CQ #7683) Intermittently slow with BCM5704 Serdes/
CIOBE Serdes.
Cause:
Firmware (v1.8.0) performs autonegotiation when link is
up and hardware autonegotiation logic indicates AUTONEG
is completed.
Change:
Changed the firmware (v1.9.0) so that it will not
perform autonegotiation when link is up and hardware
autonegotiation logic indicates AUTONEG complete.
Impact:
5704 Serdes/CIOBE Serdes.
3. Problem:
(CQ #7718) Link detection intermittently fails when ASF
is enabled.
Cause:
Contention with ASF firmware polls for PHY registers
during PHY reset routine with PHY lockup Work-Around.
Change:
Driver stops ASF firmware before accessing PHY during
initialization.
Impact:
When ASF is enabled, link establishment will take twice
as long when ASF is disabled.
4. Problem:
(CQ #7648) Fixed a problem where dynamic 10/100 or
10/100/1000 PHY auto-neg advertising based on GPIO2 state
might not work correctly and appears to take a long time
to re-establish the link.
Cause:
This issue was introduced when the PHY lockup workaround
was added. This problem only occurs on the platform where
GPIO2 state is used for dynamic PHY auto-neg.
Change:
Changed the PHY lockup workaround code so that it restores
AUTONEG configuration.
Impact:
None.
5. Problem:
(CQ #7706) Fixed a problem where driver would reports
the forced LineSpeed when there is no cable detected.
Cause:
Driver was not checking for link when LineSpeed and Duplex
were forced.
Change:
Driver checks for link always.
Impact:
None.
6. Problem:
OS2 system hangs when NIC is sharing interrupts. This was
introduced since v5.29.
Cause:
Driver does EOI on other interrupt.
Change:
Driver does EOI on its own interrupt only.
Impact:
OS2 driver only.
Version 6.42 April 29, 2003
----------------------------
Fixes:
========
1. Problem:
The PHY lockup problem described in v6.35 Fix #1 below
theoretically can affect other PHY cores in 5703 and 5705.
Cause:
Hardware bug in the PHY core. Probability of lockup is
extremely small.
Change:
Expanded the lockup detection and recovery code to 5703,
5704, and 5705. Also changed the driver to do a PHY reset
on link down.
Impact:
5703 and 5704.
2. Problem:
(CQ #7658) (CQ #7660) OS2 system crashes when uses 5703,
5703S and OS2 system cannot pass traffic with 5704, 5704S.
Cause:
Download Firmware's length was not set correct for OS2.
Change:
Set the Download Firmware's length accordingly.
Impact:
5703, 5703S, 5704 and 5704S.
3. Problem:
(CQ #7642) Driver cannot detects link change status
when driver first initialized without cable attached.
Cause:
When driver initialized without cable attached, driver
does not enable Link Change Status Interrupt.
Change:
Enable Link Change Status Interrupt when initialized even
without cable.
Impact:
None.
4. Problem:
(CQ #7648) When the cable is disconnected and reconnected,
its takes longer than expected to re-establish link.
Cause:
When the cable is reconnected, driver runs Setup PHY with
long delay.
Change:
Reduce the delay time in Setup PHY routine.
Impact:
None.
Version 6.41 April 25, 2003
----------------------------
Fixes:
========
1. Problem:
(CQ #6467) Intermittently, 5704S Fiber NICs cannot pass traffic when connect
3COM SuperStack 4900sx after a system-soft reset.
Cause:
Auto-Negotiation timing.
Change:
The fix was in the firm ware that gets download during initialization.
Impact:
5704S Fiber.
Enhancements:
=============
1. Request:
Added support for dynamic 10/100 or 10/100/1000 phy auto-neg
advertising for certain platforms.
Change:
Added a check for the state of GPIO2 during link change events
and adjust auto-neg capability advertising accordingly.
Impact:
None.
Notes:
========
1. The code base for this version is from v6.40 with the 5704 PHY lock up work-around
and zero MAC address fixes in v6.35.
2. The Lower Module is ported from PXE v6.2.4.
Version 6.35 April 18, 2003
----------------------------
Fixes:
========
1. Problem:
In some extremely rare situations, 5704/CIOBE copper NICs may not link up
after a PHY reset.
Cause:
On some 5704/CIOBE PHY cores, there is a small probability of lock up after
a PHY reset.
Change:
Added 5704/CIOB-E copper support.
Added code to detect PHY lock up after a PHY reset and reset again if lock
up is detected.
Impact:
5704/CIOB-E copper.
Notes:
========
1. The code base for this version is from v6.34.
Version 6.34 April 18, 2003
----------------------------
Fixes:
========
1. Problem:
In some extremely rare situations, 5704/CIOBE copper NICs may not link up
after a PHY reset.
Cause:
On some 5704/CIOBE PHY cores, there is a small probability of lock up after
a PHY reset.
Change:
Removed 5704/CIOB-E copper support.
Impact:
5704/CIOB-E copper.
2. Problem:
Driver Intermittently using a MAC address of all zeros.
Cause:
In some rare timing related situations, the Firmware is behind in providing
the MAC address for the Driver at the MAC Control Registers.
Change:
Driver will get the MAC address from NVRAM when the MAC address read from the
MAC Control Registers is all zeros.
Impact:
Code size increased by 944 bytes.
