* [TG3]: Fix build warning on sparc32.David S. Miller2008-03-20
| | | | | | | | | | | | Sparc MAC address support should be protected consistently with CONFIG_SPARC, but there was a stray CONFIG_SPARC64 case. Bump driver version and release date. Reported by Andrew Morton. Signed-off-by: David S. Miller <davem@davemloft.net>
* tg3: ethtool phys_id defaultStephen Hemminger2008-02-23
| | | | | | | | | | | | | When asked to blink LEDs the tg3 driver behaves when using: ethtool -p ethX The default value for data is zero, and other drivers interpret this as blink forever (or at least a really long time). The tg3 driver interprets this as blink once. All drivers should have the same behaviour.

* [TG3]: Fix supporting flowctrl codeMatt Carlson2008-01-28
| | | | | | | | | | | | | | | | | | This patch does three things. It modifies tg3_setup_flow_control() to use the administrator requested flow control settings if autonegotiation is turned off. It slightly modifies the tg3_setup_fiber_mii_phy() function to account for this new use case. And finally, it does the same for tg3_setup_copper_phy(). The copper modifications are more than a small multi-line change. The new code makes an attempt to avoid a link renegotiation if the link is active at half duplex and the only difference between the current advertised settings and requested advertised settings is the flow control advertisements.

* [TG3]: Endianness bugfix.Al Viro2007-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tg3_nvram_write_block_unbuffered() is reading data from nvram into allocated buffer before overwriting a part of it with user-supplied data. Then it feeds the entire page back to nvram. It should be storing the words it had read as little-endian, not as host-endian. Note that tg3_set_eeprom() does exactly that for padding the same data to full words before it gets passed down to tg3_nvram_write_block() and then to tg3_nvram_write_block_unbuffered(). Moreover, when we get to sending the entire thing back to nvram, we go through it word-by-word, doing essentially writel(swab32(le32_to_cpu(word)), ...) so if we want them to reach the card in host-independent endianness, we'd better really have all that buffer filled with fixed-endian. For user-supplied part we obviously do have that (it's an array of octets memcpy'd in), ditto for padding of user-supplied part to word boundaries (taken care of in tg3_set_eeprom()). The rest of the buffer gets filled by tg3_nvram_write_block_unbuffered() and it would damn better be consistent with that (and with tg3_get_eeprom(), while we are at it - there we also convert the words read from nvram to little-endian before returning the buffer to user). The bug should get triggered on big-endian boxen when set_eeprom is done for less than entire page. Then the words that should've been unaffected at all will actually get byteswapped in place in nvram. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S.

* [TG3]: Endianness annotations.Al Viro2007-12-19
| | | | | | | | | | | | | Fixed misannotations, introduced a new helper - tg3_nvram_read_le(). It gets __le32 * instead of u32 * and puts there the value converted to little-endian. A lot of callers of tg3_nvram_read() were doing that; converted them to tg3_nvram_read_le(). At that point the driver is practically endian-clean; the only remaining place is an actual bug, AFAICS; will be dealt with in the next patch.

| | | | | | | | | | | | | | 5784 and 5764 devices fail to link / pass traffic after one load / unload cycle. This happens because of a hardware bug in the new CPMU. During normal operation, the MAC depends on the PHY clock being available. When the PHY is powered down, the clock the MAC depends on is disabled. The fix is to switch the MAC clock to an alternate source before powering down the PHY, and to restore the MAC clock to the PHY source upon device resume.

* [TG3]: Fix 5761 PXEboot crashMatt Carlson2007-11-13
| | | | | | | | | | | | | | | | When 5761 devices boot the machine using PXEboot, PXE leaves the device active when it terminates. The tg3 driver has code to detect this condition and resets the device during initialization. On 5761 devices, device resets involve sending a driver state update message to the APE on the 5761. However, during this initialization stage, communications to the APE registers have not yet been set up. The driver then dereferences a NULL pointer and crashes the machine. The fix is to move the APE register access setup earlier in the initialization code to cover this condition.

Unfortunately ethtool doesn't seem to set ADVERTISED_Autoneg in the advertising field (and maybe it shouldn't have to). I'd vote that it should be fixed there, but it should also be added here just in case someone using ethtool ioctls in their own application gets what they want. Adding that flag in tg3_set_settings seemed like the most logical place since the driver works fine on boot.

* [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.
