* [PATCH v3 79/97] ath9k_hw: skip WEP aggregation enable code for AR9003
From: Luis R. Rodriguez @ 2010-04-15 21:39 UTC (permalink / raw)
To: linville; +Cc: linux-wireless, Luis R. Rodriguez
In-Reply-To: <1271367582-992-1-git-send-email-lrodriguez@atheros.com>
The AR9002 hardware code enables aggregation for WEP but
mac80211 doesn't enable aggregation with WEP, and the AR9003
code family does not need this so skip it for now for AR9003
but leave the code and annotate we should eventually consider
how to remove this in consideration for the HAL unification
goals.

cards.

- * ath9k_hw_updatetxtriglevel - adjusts the frame trigger level
- *
- * @ah: atheros hardware struct
- * @bIncTrigLevel: whether or not the frame trigger level should be updated
- *
- * The frame trigger level specifies the minimum number of bytes,
- * in units of 64 bytes, that must be DMA'ed into the PCU TX FIFO
- * before the PCU will initiate sending the frame on the air. This can
- * mean we initiate transmit before a full frame is on the PCU TX FIFO.
- * Resets to 0x1 (meaning 64 bytes or a full frame, whichever occurs
- * first)
- *
- * Caution must be taken to ensure to set the frame trigger level based
- * on the DMA request size. For example if the DMA request size is set to
- * 128 bytes the trigger level cannot exceed 6 * 64 = 384. This is because
- * there need to be enough space in the tx FIFO for the requested transfer
- * size. Hence the tx FIFO will stop with 512 - 128 = 384 bytes. If we set
- * the threshold to a value beyond 6, then the transmit will hang.
- *
- * Current dual stream devices have a PCU TX FIFO size of 8 KB.
- * Current single stream devices have a PCU TX FIFO size of 4 KB, however,
- * there is a hardware issue which forces us to use 2 KB instead so the
- * frame trigger level must not exceed 2 KB for these chipsets.

* [PATCH v3 68/97] ath9k_hw: restore mac address reading logic
From: Luis R. Rodriguez @ 2010-04-15 21:39 UTC (permalink / raw)
To: linville; +Cc: linux-wireless, Luis R. Rodriguez
In-Reply-To: <1271367582-992-1-git-send-email-lrodriguez@atheros.com>
Once upon a time the AR_EEPROM_MAC macro was added to let us
add a random attribute to the three 4-bytes of MAC addresses
entries we read from the EEPROM. This was good while a random
high-enough value was used which did not conflict with any
of the already existing enum eeprom_param values. With AR9003
support the enums overlap and it means we either increment
the random offset or just restore the reading logic to match
what the HAL has. I choose to do the later to synchronize
the logic on both code bases.
This should fix reading the MAC address from the EEPROM
on AR9003 hardware.
