In some cases the ethernet interface goes down for a short time +after'ifconfig wlan0 up'. +2. Sometimes the device simply reboots itself after 'ifconfig wlan0 up'. + +After I have added some printk statements into the code, I noticed that the +ar5416 and ar9100 devices use the same initval arrays currently. I assume +that they requires different initialization, because we have different +arrays for them. + +Although I have no detailed knowledge about the evolution of the ath9k devices, +but the version checking macros for ther AR5416 cards seemed weird enough, so I +have replaced them. Unfortunately, this leaded to very bad performance with the +ar5416 cards I have, but the driver was working on the ar913x boards. + +After some digging, I have found an interesting ifdef statement in Sam's current +HAL. In his ar5416Common initval array, this ifdef conditionally selects the +right RTC register offsets for the ar5416/ar9100 devices. The strange thing, +that in the ath9k driver the ar5416 specific RTC register offsets are used in +the ar5416Common_ar9100 array, while the ar9100 specific offsets are used in the +ar5416Common. + +After I have renamed the arrays and tested the ath9k driver with the new +settings on the ar9100 devices, the strange problems I have mentioned above +disappeared. Unfortunately I have no ar5418 devices so I can't test them, +but they are using the same array as before so this change should not +cause problems on them. + +Regards, +Gabor + +diff --git a/drivers/net/wireless/ath9k/initvals.h b/drivers/net/wireless/ath9k/initvals.h +index d492363..4eb8b59 100644 +--- a/drivers/net/wireless/ath9k/initvals.h ++++ b/drivers/net/wireless/ath9k/initvals.h +@@ -14,7 +14,7 @@ + * OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE. + */ + +-static const u32 ar5416Modes_9100[][6] = { ++static const u32 ar5416Modes[][6] = { + { 0x00001030, 0x00000230, 0x00000460, 0x000002c0, 0x00000160, 0x000001e0 }, + { 0x00001070, 0x00000168, 0x000002d0, 0x00000318, 0x0000018c, 0x000001e0 }, + { 0x000010b0, 0x00000e60, 0x00001cc0, 0x00007c70, 0x00003e38, 0x00001180 }, +@@ -78,7 +78,7 @@ static const u32 ar5416Modes_9100[][6] = { + { 0x0000a334, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000 }, + };
