2006-05-12[TG3]: ethtool always report port is TP.Karsten Keil
Even with fiber cards ethtool reports that the connected port is TP, the patch fix this. Signed-off-by: Karsten Keil <kkeil@suse.de> Acked-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-05-09[TG3]: Fix possible NULL deref in tg3_run_loopback().Jesper Juhl
tg3_run_loopback doesn't check that dev_alloc_skb() returns anything useful. Even if dev_alloc_skb() fails to return an skb to us we'll happily go on and assume it did, so we risk dereferencing a NULL pointer. Much better to fail gracefully by returning -ENOMEM than crashing here. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-04-29[TG3]: Fix bug in nvram writeMichael Chan
Fix bug in nvram write function. If the starting nvram address offset happens to be the last dword of the page, the NVRAM_CMD_LAST bit will not get set in the existing code. This patch fixes the bug by changing the "else if" to "if" so that the last dword condition always gets checked. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-04-29[TG3]: Add reset_phy parameter to chip reset functionsGary Zambrano
Add a reset_phy parameter to tg3_reset_hw() and tg3_init_hw(). With the full chip reset during MAC address change, the automatic PHY reset during chip reset will cause a link down and bonding will not work properly as a result. With this reset_phy parameter, we can do a chip reset without link down when changing MAC address or MTU.

2006-04-29[TG3]: Reset chip when changing MAC addressMichael Chan
Do the full chip reset when changing MAC address if ASF is enabled. ASF sometimes uses a different MAC address than the driver. Without the reset, the ASF MAC address may be overwritten when the driver's MAC address is changed. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2006-04-29[TG3]: Call netif_carrier_off() during phy resetMichael Chan
Add netif_carrier_off() call during tg3_phy_reset(). This is needed to properly track the netif_carrier state in cases where we do a PHY reset with interrupts disabled. The SerDes code will not run properly if the netif_carrier state is wrong. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-04-09[TG3]: Speed up SRAM access (2nd version)Michael Chan
Speed up SRAM read and write functions if possible by using MMIO instead of config. cycles. With this change, the post reset signature done at the end of D3 power change must now be moved before the D3 power change. IBM reported a problem on powerpc blades during ethtool self test that was caused by the memory test taking excessively long. Config. cycles are very slow on powerpc and the memory test can take more than 10 seconds to complete using config. cycles. David Miller informed me that an earlier version of the patch caused problems on sparc64 systems with built-in tg3 chips. This version fixes the problem by excluding all SUN built-in tg3 chips from doing MMIO SRAM access. TG3_FLAG_EEPROM_WRITE_PROT is also set unconditionally when TG3_FLG2_SUN_570X is set. This should be sane as all SUN chips are built-in and do not require Vaux switching. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-03-20[TG3]: netif_carrier_off runs too early; could still be queued when init failsJeff Mahoney
Move the netif_carrier_off() call from tg3_init_one()-> tg3_init_link_config() to tg3_open() as is the convention for most other network drivers. I was getting a panic after a tg3 device failed to initialize due to DMA failure. The oops pointed to the link watch queue with spinlock debugging enabled. Without spinlock debugging, the Oops didn't occur. I suspect that the link event was getting queued but not executed until after the DMA test had failed and the device was freed. The link event was then operating on freed memory, which could contain anything. With this patch applied, the Oops no longer occurs.

2006-03-19[TG3]: 40-bit DMA workaround part 2Michael Chan
The 40-bit DMA workaround recently implemented for 5714, 5715, and 5780 needs to be expanded because there may be other tg3 devices behind the EPB Express to PCIX bridge in the 5780 class device. For example, some 4-port card or mother board designs have 5704 behind the 5714. All devices behind the EPB require the 40-bit DMA workaround.
