2011-12-07fsl_pq_mdio: Clean up tbi address configurationAndy Fleming
The code for setting the address of the internal TBI PHY was convoluted enough without a maze of ifdefs. Clean it up a bit so we allow the logic to fail down to -ENODEV at the end of the if/else ladder, rather than using ifdefs to repeat the same failure code over and over. Also, remove the support for the auto-configuration. I'm not aware of anyone using it, and it ends up using the bus mutex before it's been initialized.

2011-12-07net/fec: fix the use of pdev->idShawn Guo
The pdev->id is used in several places for different purpose. All these uses assume it's always the id of fec device which is >= 0. However this is only true for non-DT case. When DT plays, pdev->id is always -1, which will break these pdev->id users. Instead of fixing all these users one by one, this patch introduces a new member 'dev_id' to 'struct fec_enet_private' for holding the correct fec device id, and replaces all the existing uses of pdev->id with this dev_id.

2011-12-05r8169: fix Rx index race between FIFO overflow recovery and NAPI handler.françois romieu
Since 92fc43b4159b518f5baae57301f26d770b0834c9, rtl8169_tx_timeout ends up resetting Rx and Tx indexes and thus racing with the NAPI handler via -> rtl8169_hw_reset -> rtl_hw_reset -> rtl8169_init_ring_indexes What about returning to the original state ? rtl_hw_reset is only used by rtl8169_hw_reset and rtl8169_init_one. The latter does not need rtl8169_init_ring_indexes because the indexes still contain their original values from the newly allocated network device private data area (i.e. 0). rtl8169_hw_reset is used by: 1. rtl8169_down Helper for rtl8169_close. rtl8169_open explicitely inits the indexes anyway. 2. rtl8169_pcierr_interrupt Indexes are set by rtl8169_reinit_task. 3. rtl8169_interrupt rtl8169_hw_reset is needed when the device goes down. See 1. 4. rtl_shutdown System shutdown handler. Indexes are irrelevant. 5. rtl8169_reset_task Indexes must be set before rtl_hw_start is called. 6. rtl8169_tx_timeout Indexes should not be set. This is the job of rtl8169_reset_task anyway. The removal of rtl8169_hw_reset in rtl8169_tx_timeout and its move in rtl8169_reset_task do not change the analysis.

2011-12-05r8169: Rx FIFO overflow fixes.françois romieu
Realtek has specified that the post 8168c gigabit chips and the post 8105e fast ethernet chips recover automatically from a Rx FIFO overflow. The driver does not need to clear the RxFIFOOver bit of IntrStatus and it should rather avoid messing it. The implementation deserves some explanation: 1. events outside of the intr_event bit mask are now ignored. It enforces a no-processing policy for the events that either should not be there or should be ignored. 2. RxFIFOOver was already ignored in rtl_cfg_infos[RTL_CFG_1] for the whole 8168 line of chips with two exceptions: - RTL_GIGA_MAC_VER_22 since b5ba6d12bdac21bc0620a5089e0f24e362645efd ("use RxFIFO overflow workaround for 8168c chipset."). This one should now be correctly handled. - RTL_GIGA_MAC_VER_11 (8168b) which requires a different Rx FIFO overflow processing. Though it does not conform to Realtek suggestion above, the updated driver includes no change for RTL_GIGA_MAC_VER_12 and RTL_GIGA_MAC_VER_17. Both are 8168b. RTL_GIGA_MAC_VER_12 is common and a bit old so I'd rather wait for experimental evidence that the change suggested by Realtek really helps or does not hurt in unexpected ways. Removed case statements in rtl8169_interrupt are only 8168 relevant. 3. RxFIFOOver is masked for post 8105e 810x chips, namely the sole 8105e (RTL_GIGA_MAC_VER_30) itself.

2011-11-23ehea: Reduce memory usage in buffer poolsAnton Blanchard
Now that we enable multiqueue by default the ehea driver is using quite a lot of memory for its buffer pools. With 4 queues we consume 64MB in the jumbo packet ring, 16MB in the medium packet ring and 16MB in the tiny packet ring. We should only fill the jumbo ring once the MTU is increased but for now halve it's size so it consumes 32MB. Also reduce the tiny packet ring, with 4 queues we had 16k entries which is overkill.

2011-11-23qlge: fix size of external list for TX address descriptorsThadeu Lima de Souza Cascardo
When transmiting a fragmented skb, qlge fills a descriptor with the fragment addresses, after DMA-mapping them. If there are more than eight fragments, it will use the eighth descriptor as a pointer to an external list. After mapping this external list, called OAL to a structure containing more descriptors, it fills it with the extra fragments. However, considering that systems with pages larger than 8KiB would have less than 8 fragments, which was true before commit a715dea3c8e, it defined a macro for the OAL size as 0 in those cases. Now, if a skb with more than 8 fragments (counting skb->data as one fragment), this would start overwriting the list of addresses already mapped and would make the driver fail to properly unmap the right addresses on architectures with pages larger than 8KiB. Besides that, the list of mappings was one size too small, since it must have a mapping for the maxinum number of skb fragments plus one for skb->data and another for the OAL. So, even on architectures with page sizes 4KiB and 8KiB, a skb with the maximum number of fragments would make the driver overwrite its counter for the number of mappings, which, again, would make it fail to unmap the mapped DMA addresses.

This change makes sure that tx_packets/rx_bytes ifconfig counters are updated even on NICs that don't provide hardware support for these stats: they are now updated in software. For the sake of consistency, we also now have tx_bytes updated in software (hardware counters include ethernet CRC, and software doesn't account for it). This reverts parts of: - "forcedeth: statistics optimization" (21828163b2) - "forcedeth: Improve stats counters" (0bdfea8ba8) - "forcedeth: remove unneeded stats updates" (4687f3f364) Tested: pktgen + loopback (http://patchwork.ozlabs.org/patch/124698/) reports identical tx_packets/rx_packets and tx_bytes/rx_bytes.

2011-11-09net/ll_temac: FIX : Wait for indirect wait to endRicardo Ribalda
While tracing down a connectivity problem on the temac I connected a probe to the Cross bar irq, and it was triggered when doing ifdown->ifup. This is fixed once waiting for the indirect write to end. Since it is not on the hot path there is no performance loss.

2011-11-09net/temac: FIX segfault when process old irqsRicardo Ribalda
Do not enable the irq until the scatter gather registers are ready to handle the data. Otherwise an irq from a packet send/received before last close can lead to an access to an invalid memory region on the irq handler. Also, stop the dma engine on close.

2011-11-08sunhme: Allow usage on SBI based SBus systemsoftedal
To prevent the SBus driver for Sun Happy Meal cards from being loaded for PCI cards utilizing the same chipset, a filter was added to the probe function in commit 0b492fce3d72d982a7981905f85484a1e1ba7fde. The filter was implemented by checking the name of the parent node in the OF tree. This patch extends this filter, so that the driver will load on SBus systems that are based upon SBI SBus Bridges.

2011-11-08r8169: increase the delay parameter of pm_schedule_suspendhayeswang
The link down would occur when reseting PHY. And it would take about 2 ~ 5 seconds from link down to link up. If the delay of pm_schedule_suspend is not long enough, the device would enter runtime_suspend before link up. After link up, the device would wake up and reset PHY again. Then, you would find the driver keep in a loop of runtime_suspend and rumtime_resume.
