* netdev: bfin_mac: add support for IEEE 1588 PTPBarry Song2010-05-183-1/+362
| | | | | | | | | Newer on-chip MAC peripherals support IEEE 1588 PTP in the hardware, so extend the driver to support this functionality. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* drivers/net/usb/asix.c: Fix unaligned accessesNeil Jones2010-05-181-1/+33
| | | | | | | | | | Using this driver can cause unaligned accesses in the IP layer This has been fixed by aligning the skb data correctly using the spare room left over by the 4 byte header inserted between packets by the device.

| | | | | | | | | Adds support for resuming from suspend for IBM virtual ethernet devices. We may have lost an interrupt over the suspend, so we just kick the interrupt handler to process anything that is outstanding.

| | * vhost: fix barrier pairingMichael S. Tsirkin2010-05-121-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to memory-barriers.txt, an smp memory barrier in guest should always be paired with an smp memory barrier in host, and I quote "a lack of appropriate pairing is almost certainly an error". In case of vhost, failure to flush out used index update before looking at the interrupt disable flag could result in missed interrupts, resulting in networking hang under stress. This might happen when flags read bypasses used index write. So we see interrupts disabled and do not interrupt, at the same time guest writes flags value to enable interrupt, reads an old used index value, thinks that used ring is empty and waits for interrupt. Note: the barrier we pair with here is in drivers/virtio/virtio_ring.c, function vring_enable_cb. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Juan Quintela <quintela@redhat.com>

| * | | wimax/i2400m: Reset the TX FIFO indices when allocating the TX FIFO in ↵Cindy H Kao2010-05-111-8/+21

When a device reset happens and the TX FIFO is released/re-allocated, a new block of memory may be allocated for the TX FIFO, therefore tx_msg should be cleared so that no any TX threads (tx_worker, tx) would access to the out-of-date addresses. Also, the TX threads use tx_in and tx_out to decide where to put the new host-to-device messages and from where to copy them to the device HW FIFO, these indices have to be cleared so after the TX FIFO is re-allocated during the reset, the indices both refer to the head of the FIFO, ie. a new start. The same rational applies to tx_msg_size and tx_sequence. To protect the indices from being accessed by multiple threads simultaneously, the lock tx_lock has to be obtained before the initializations and released afterwards.

| * | | wimax/i2400m: add the error recovery mechanism on TX pathCindy H Kao2010-05-113-0/+92

The intention is to bring back the device to some known state whenever TX sees -110 (-ETIMEOUT) on copying the data to the HW FIFO. The TX failure could mean a device bus stuck or function stuck, so the current error recovery implementation is to trigger a bus reset and expect this can bring back the device. Since the TX work is done in a thread context, there may be a queue of TX works already that all hit the -ETIMEOUT error condition because the device has somewhat stuck already. We don't want any consecutive bus resets simply because multiple TX works in the queue all hit the same device erratum, the flag "error_recovery" is introduced to denote if we are ready for taking any error recovery.

| * | | wimax/i2400m: fix for missed reset events if triggered by dev_reset_handle()Cindy H Kao2010-05-112-16/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is only seen on SDIO interface since on USB, a bus reset would really re-probe the driver, but on SDIO interface, a bus reset will not re-enumerate the SDIO bus, so no driver re-probe is happening. Therefore, on SDIO interface, the reset event should be still detected and handled by dev_reset_handle(). Problem description: Whenever a reboot barker is received during operational mode (i2400m->boot_mode == 0), dev_reset_handle() is invoked to handle that function reset event. dev_reset_handle() then sets the flag i2400m->boot_mode to 1 indicating the device is back to bootmode before proceeding to dev_stop() and dev_start(). If dev_start() returns failure, a bus reset is triggered by dev_reset_handle(). The flag i2400m->boot_mode then remains 1 when the second reboot barker arrives. However the interrupt service routine i2400ms_rx() instead of invoking dev_reset_handle() to handle that reset event, it filters out that boot event to bootmode because it sees the flag i2400m->boot_mode equal to 1. The fix: Maintain the flag i2400m->boot_mode within dev_reset_handle() and set the flag i2400m->boot_mode to 1 when entering dev_reset_handle(). It remains 1 until the dev_reset_handle() issues a bus reset. ie: the bus reset is taking place just like it happens for the first time during operational mode. To denote the actual device state and the state we expect, a flag i2400m->alive is introduced in addition to the existing flag i2400m->updown. It's maintained with the same way for i2400m->updown but instead of reflecting the actual state like i2400m->updown does, i2400m->alive maintains the state we expect. i2400m->alive is set 1 just like whenever i2400m->updown is set 1. Yet i2400m->alive remains 1 since we expect the device to be up all the time until the driver is removed. See the doc for @alive in i2400m.h. An enumeration I2400M_BUS_RESET_RETRIES is added to define the maximum number of bus resets that a device reboot can retry. A counter i2400m->bus_reset_retries is added to track how many bus resets have been retried in one device reboot. If I2400M_BUS_RESET_RETRIES bus resets were retried in this boot, we give up any further retrying so the device would enter low power state. The counter i2400m->bus_reset_retries is incremented whenever dev_reset_handle() is issuing a bus reset and is cleared to 0 when dev_start() is successfully done, ie: a successful reboot.

* | | | rndis_host: Poll status channel before control channelBen Hutchings2010-05-161-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some RNDIS devices don't respond on the control channel until polled on the status channel. In particular, this was reported to be the case for the 2Wire HomePortal 1000SW. This is roughly based on a patch by John Carr <john.carr@unrouted.co.uk> which is reported to be needed for use with some Windows Mobile devices and which is currently applied by Mandriva.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocating memory can fail, and since we have the memory we need in sky2_resume when sky2_suspend is called, just stop the hardware without freeing the memory it's using. This avoids the possibility of failing because we can't allocate memory in sky2_resume(), and allows sharing code with sky2_restart().
