| | | | | | | | | | | | | | | | | | | | | | | | | | All drivers that select MII also need to select NET_CORE because MII depends on it. This is a bit ridiculous because NET_CORE is just a menu option that doesn't enable any code by itself. There is also no need for it to be a visible option, since its users all select it.

The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>
| * tg3: Wait for boot code to finish after power onNithin Sujir2013-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some systems that don't need wake-on-lan may choose to power down the chip on system standby. Upon resume, the power on causes the boot code to startup and initialize the hardware. On one new platform, this is causing the device to go into a bad state due to a race between the driver and boot code, once every several hundred resumes. The same race exists on open since we come up from a power on. This patch adds a wait for boot code signature at the beginning of tg3_init_hw() which is common to both cases. If there has not been a power-off or the boot code has already completed, the signature will be present and poll_fw() returns immediately. Also return immediately if the device does not have firmware.

* | tg3: Prevent system hang during repeated EEH errors.Michael Chan2013-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current tg3 code assumes the pci_error_handlers to be always called in sequence. In particular, during ->error_detected(), NAPI is disabled and the device is shutdown. The device is later reset and NAPI re-enabled in ->slot_reset() and ->resume(). In EEH, if more than 6 errors are detected in a hour, only ->error_detected() will be called. This will leave the driver in an inconsistent state as NAPI is disabled but netif_running state is still true. When the device is later closed, we'll try to disable NAPI again and it will loop forever. We fix this by closing the device if we encounter any error conditions during the normal sequence of the pci_error_handlers. v2: Remove the changes in tg3_io_resume() based on Benjamin Poirier's feedback.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the Broadcom BCM6345 SoC Ethernet. BCM6345 has a slightly different and older DMA engine which requires the following modifications: - the width of the DMA channels on BCM6345 is 64 bytes vs 16 bytes, which means that the helpers enet_dma{c,s} need to account for this channel width and we can no longer use macros - BCM6345 DMA engine does not have any internal SRAM for transfering buffers - BCM6345 buffer allocation and flow control is not per-channel but global (done in RSET_ENETDMA) - the DMA engine bits are right-shifted by 3 compared to other DMA generations - the DMA enable/interrupt masks are a little different (we need to enabled more bits for 6345) - some register have the same meaning but are offsetted in the ENET_DMAC space so a lookup table is required to return the proper offset The MAC itself is identical and requires no modifications to work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current bcm63xx_enet driver always uses bcmenet_shared_base whenever it needs to access DMA channel configuration space or access the DMA channel state RAM. Split these register in 3 parts to be more accurate: - global DMA configuration - per DMA channel configuration space - per DMA channel state RAM space This is preliminary to support new chips where the global DMA configuration remains the same, but there is a varying number of DMA channels located at a different memory offset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was recently found out that GSO on 57710/57711 was broken, due to packets being sent without a valid IP checksum. Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this issue, but failed to set the correct IP checksum when receiving GSO packets via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed to calculate IP checksum were erroneously set in the incorrect buffer descriptor.

* | net: ethernet: use platform_{get,set}_drvdata()Jingoo Han2013-05-25
| | | | | | | | | | | | | | | | | | | | | | | | Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike the boot signature that needs to be set before every reset, the ape state only needs to be updated to tell the firmware that the driver is now taking/releasing control of the hardware. Move the calls to tg3_ape_driver_state_change() to better, more appropriate places. Also, the firmware does not distinguish between SUSPEND and START states anymore. Remove the SUSPEND case in the switch. Signed-off-by: Nithin Nayak Sujir <nsujir@broadcom.com> Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * tg3: Ensure boot code has completed initialization before accessing hardwareNithin Sujir2013-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After resetting the device, the driver waits for a signature to be updated to know that firmware has completed initialization. However, the call to tg3_poll_fw() is being done too late and we're writing to the GRC_MODE register before it has completely initialized, causing contention with firmware. This logic has existed since day one but is causing PCIE link to go down randomly at startup on one platform once every few hundred reboots. Move the tg3_poll_fw() up to before we write to the GRC_MODE register after reset.

| * bnx2x: Fix GSO for 57710/57711 chipsYuval Mintz2013-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with commit 91226790bbe2dbfbba48dd79d49f2b38ef10eb97 `bnx2x: use FW 7.8.17', the bnx2x driver no longer requests the FW to perform IP checksums for IPv4 packets. This behaviour needs to be revised for 57710/57711 chips - when using GSO, if the driver will not set the IP checksum flag then packets will be transmitted by the chip without a valid IP checksum, resulting in a drop of all such packets on the receiver-side.
