      [PATCH] S2io: hardware fixes · 3fbc24f1
      Raghavendra Koushik authored 
      1. Xena3's with a set of subsystem IDs had Link LED problems, fixed
that specifically for them.

2. To write into the Keyed Mac_Cfg register to enable broadcast,
writing two 32 bit writes into it along with a write to the key
register rather than a single write to key and a 64 bit write to
mac_cfg. This is necessary on 32 bit systems where a writeq(64 bit
write) is actually two writel (32 bit writes).

3. Writes to some special registers mentioned in UG is being done by
a special macro which defines which 32 bits of the 64 bit register
is to be written first. Again this applies only on 32 bit systems.

4. Configured pause frame related water marks and a shared_split
value which describes the Max TXDMA related split transaction that
can be used without giving room for the Rx transactions.

5. The mac_rmac_err_reg R1 register will be cleared in  the interrupt
handler itself rather than in the scheduled task as was being done
previously.

6. Even on PCC_FB_ECC error the card will be reset by disabling
adapter enable bit.

      [PATCH] S2io: optimizations · b3ea38cb
      Raghavendra Koushik authored 
      1. Definitions of LOW and PANIC levels of the Rx buffers have changed.

2. In wait_for_cmd_complete there is no longer a writeq but just a
read and wait for strobe bit to reset.

3. In s2io_isr, the isr_lock has been done away with also the NICs
interrupt are no longer disabled explicitly on entering the interrupt
handler and re-enabled again before leaving it.

4. Also clearing the semaphore "tasklet_status" when exiting
erroneously from s2io_isr after failing fill_rx_buffer call.

5. The set/reset Tx Csum function through ethtool was added to the
ethtool_ops structure.

6. Added a Rx side error code in the rx_osm_handler function.

7. No longer stopping and waking Tx queue when link state changes in
s2io_link function.

8. removed the isr_lock spinlock from the s2io_nic structure.

9. changed parameters which determine thresholds(LOW and PANIC)
to replenish Rx buffers.
   This has been found to result in better performance.

      [PATCH] S2io: sw bug fixes · 10a7bfef
      Raghavendra Koushik authored 
      1. In free_rx_buffers clearing out RxDs not owned by Xena.

2. In alarm_intr_handler, when a serr error occurs, schedule a task
to reset the card rather than stopping Tx queue.

3. In s2io_close freeing IRQ before calling s2io_reset also added a
new call to flush queued tasks. This is not done if the s2io_close
itself is called from a queued task like s2io_restart_nic.

4. read_eeprom function has been changed such that data to be returned
is sent as an input argument and the return value represents a
pass/fail. The previous implementation as Randy had pointed out was
error prone as on failure it returned -1 which can be interpreted
as all ff's, so any data area which contained ff's in the eeprom was
likely to be treated as an error.

5. Added a flag "task_flag" to track if the call to s2io_close is
coming from the s2io_restart_nic function or from the ifconfig <I/F>
down called by user.

6. Moved register_netdev call from just after setting entry points
to the end of the s2io_init_nic function.

7. In s2io.h field added a new member into the s2io_nic structure
called "task_flag".

      Raghavendra Koushik authored 
      1. Indentation, change in comment styles, variable name changes etc.
2. Changed the value written to dtx_control register to force XGXS reset.
3. weight parameter(NAPI) changed to 90 for better performance.
