* niu: Determine the # of ports from the card's VPD dataMatheos Worku2008-05-121-32/+21
| | | | | | | | | | | | Determine the number of physical ports from the card's VPD data. Previous fix failed on Maramba platform which doesn't have the "board-model" property. This fix uses the "model" property which exists on all cards and Neptune based motherboards. cstyle cleanup included. Signed-off-by: Matheos Worku <matheos.worku@sun.com> Signed-off-by: David S.

* niu: Fix probing regression for maramba on-board chips.David S. Miller2008-05-041-4/+7
| | | | | | | | | | | | | | | | Changeset 7f7c4072ea552f97a0898331322f71986a97299c ("niu: Determine the # of ports from the card's VPD data") caused maramba on-board NIU ports to stop probing properly. The old code had a fallback that would use a num_ports value of 4 if all the probing methods failed, but that was removed. This restores the fallback of 4 ports, to get things working again. Bump driver version and release date. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | From: Matheos Worku <Matheos.Worku@Sun.COM> 1) niu_enable_alt_mac() needs to be adjusted so that the mask is computed properly for the BMAC case. 2) BMAC has 6 alt MAC addresses available, not 7. Signed-off-by: David S. Miller <davem@davemloft.net>

* [NIU]: Fix 1G PHY link state handling.David S. Miller2008-01-171-0/+3
| | | | | | | | | | | | The code in link_status_1g() computes the active speed and duplex but does not update the link config state with those values. As a result the link speed is not reported correctly and the XIF is not reprogrammed properly on link up events. Signed-off-by: David S. Miller <davem@davemloft.net>
* [NIU]: Support for Marvell PHYMirko Lindner2008-01-101-20/+198
| | | | | | | | | | | | | From: Mirko Lindner <mlindner@marvell.com> This patch makes necessary changes in the Neptune driver to support the new Marvell PHY. It also adds support for the LED blinking on Neptune cards with Marvell PHY. All registers are using defines in the niu.h header file as is already done for the BCM8704 registers.

* [NIU]: Fix potentially stuck TCP socket send queues.David S. Miller2008-01-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for the TX ring to have packets sit in it for unbounded amounts of time. The only way to defer TX interrupts in the chip is to periodically set "mark" bits, when processing of a TX descriptor with the mark bit set is complete it triggers the interrupt for the TX queue's LDG. A consequence of this kind of scheme is that if packet flow suddenly stops, the remaining TX packets will just sit there. If this happens, since those packets could be charged to TCP socket send queues, such sockets could get stuck. The simplest solution is to divorce the socket ownership of the packet once the device takes the SKB, by using skb_orphan() in niu_start_xmit(). In hindsight, it would have been much nicer if the chip provided two interrupt sources for TX (like basically every other ethernet chip does). Namely, keep the "mark" bit, but also signal the LDG when the TX queue becomes completely empty. That way there is no need to have a deadlock breaker like this. Signed-off-by: David S.

* [NIU]: Fix slowpath interrupt handling.Matheos Worku2008-01-081-11/+23
| | | | | | | | | | | | | | | niu_slowpath_interrupt() expects values to be setup in lp->{v0,v1,v2} but they aren't. That's only done by niu_schedule_napi() which is done later in the interrupt path. If niu_rx_error() returns zero, and v0 is clear, hit the RX_DMA_CTL_STATE register with a RX_DMA_CTL_STAT_MEX. Only emit verbose RX error logs if a fatal channel or port error is signalled. Other cases will be recorded into statistics by niu_log_rxchan_errors(). Signed-off-by: David S. Miller <davem@davemloft.net>

* [NIU]: Cleanup PAGE_SIZE checks a bitOlof Johansson2007-10-221-29/+5
| | | | | | | | | | | | | | | | | | | | | | I get the following warning from a powerpc allyesconfig of current mainline: drivers/net/niu.c: In function 'niu_size_rbr': drivers/net/niu.c:3113: warning: large integer implicitly truncated to unsigned type PAGE_SIZE in this case is 64KB, so I don't quite get why gcc can't tell that the line in question will never be reached. I suggest the following instead, but I can unfortunately not do anything but build test it. Also, the driver does some other checks to make sure that PAGE_SIZE is a power of two (BUILD_BUG_ON() in niu_init()), doesn't seem like that could ever be untrue? Or are there really archs with non-power-of-two PAGE_SIZE? Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: David S. Miller <davem@davemloft.net>
