| | | | | | | | | | The only R8A7740 specific #ifdef hindering ARM multiplatform build is left in sh_eth_rx(): it covers the code shifting Rx buffer descriptor word 0 by 16. Get rid of the #ifdef by adding 'shift_rd0' field to the 'struct sh_eth_cpu_data', making the shift dependent on it, and setting it to 1 for the R8A7740 case...

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>

| * alx: add a simple AR816x/AR817x device driverJohannes Berg2013-06-189-0/+4568
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a very simple driver, based on the original vendor driver that Qualcomm/Atheros published/submitted previously, but reworked to make the code saner. However, it also lost a number of features (TSO/GSO, VLAN acceleration and multi- queue support) in the process, as well as debugging support features I didn't have any use for. The only thing I left is checksum offload. More features can obviously be added, but this seemed like a good start for having a driver in mainline at all. Johannes Stezenbach has verified that the driver works on AR8161, I have a AR8171 myself. The E2200 device ID I found on github in somebody's repository.

| * tg3: Wait for boot code to finish after power onNithin Sujir2013-06-131-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* | 3c59x: consolidate error cleanup in vortex_init_one()Sergei Shtylyov2013-06-121-13/+12
| | | | | | | | | | | | | | | | | | | | The PCI driver's probe() method duplicates the error cleanup code each time it has to do error exit. Consolidate the error cleanup code in one place and use *goto* to jump to the right places.

When receiving a packet we use skb_mark_ll to record the napi it came from. Add each napi to the napi_hash right after netif_napi_add().

* | bcm63xx_enet: add support for Broadcom BCM63xx integrated gigabit switchMaxime Bizon2013-06-102-12/+998
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer Broadcom BCM63xx SoCs: 6328, 6362 and 6368 have an integrated switch which needs to be driven slightly differently from the traditional external switches. This patch introduces changes in arch/mips/bcm63xx in order to: - register a bcm63xx_enetsw driver instead of bcm63xx_enet driver - update DMA channels configuration & state RAM base addresses - add a new platform data configuration knob to define the number of ports per switch/device and force link on some ports - define the required switch registers On the driver side, the following changes are required: - the switch ports need to be polled to ensure the link is up and running and RX/TX can properly work - basic switch configuration needs to be performed for the switch to forward packets to the CPU - update the MIB counters since the integrated Signed-off-by: Maxime Bizon <mbizon@freebox.fr> Signed-off-by: Jonas Gorski <jogo@openwrt.org> Signed-off-by: David S.

* | bcm63xx_enet: split DMA channel register accessesMaxime Bizon2013-06-101-56/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
