* rapidio: fix use of non-compatible registersAlexandre Bounine2011-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | Replace/remove use of RIO v.1.2 registers/bits that are not forward-compatible with newer versions of RapidIO specification. RapidIO specification v.1.3 removed Write Port CSR, Doorbell CSR, Mailbox CSR and Mailbox and Doorbell bits of the PEF CAR. Use of removed (since RIO v.1.3) register bits affects users of currently available 1.3 and 2.x compliant devices who may use not so recent kernel versions. Removing checks for unsupported bits makes corresponding routines compatible with all versions of RapidIO specification. Therefore, backporting makes stable kernel versions compliant with RIO v.1.3 and later as well.

* | bonding:reset backup and inactive flag of slavePeter Pan(潘卫平)2011-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eduard Sinelnikov (eduard.sinelnikov@gmail.com) found that if we change bonding mode from active backup to round robin, some slaves are still keeping "backup", and won't transmit packets. As Jay Vosburgh(fubar@us.ibm.com) pointed out that we can work around that by removing the bond_is_active_slave() check, because the "backup" flag is only meaningful for active backup mode. But if we just simply ignore the bond_is_active_slave() check, the transmission will work fine, but we can't maintain the correct value of "backup" flag for each slaves, though it is meaningless for other mode than active backup. I'd like to reset "backup" and "inactive" flag in bond_open, thus we can keep the correct value of them. As for bond_is_active_slave(), I'd like to prepare another patch to handle it. V2: Use C style comment. Move read_lock(&bond->curr_slave_lock). Replace restore with reset, for active backup mode, it means "restore", but for other modes, it means "reset".

* | drivers/net/can/sja1000/plx_pci.c: eliminate double freeJulia Lawall2011-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this code, the failure_cleanup label calls the function plx_pci_del_card, which frees everything in the card->net_dev array. dev is placed in this array immediately after allocation, so the two subsequent jumps to failure_cleanup should not also call free_sja1000dev, but the second one does. If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on dev. Because dev is already in the card->net_dev array, this implies that when plx_pci_del_card is later called, it may get freed again. So that entry is reset to NULL after the free. Finally, if there is a problem with one channel, there will be a hole in the array. card->channels counts the number of channels that have succeeded, and does not keep track of the index of the largest element in the array that is valid. So the loop in plx_pci_del_card is changed to go up to PLX_PCI_MAX_CHAN, which is only 2. Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S. Miller <davem@davemloft.net>

In promiscuous mode the filter table is cleared to in order to disable filtering. However, if a vlan device is subsequently created that vlan will be added to the filter, re-engaging it. As a result, not only do we not see all the vlans in promiscuous mode, we don't even see vlans for which a filter was previously created. CC: Scott J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the Manageability Engine (ME) is enabled on 82579, it periodically accesses some MAC CSR registers. There is an arbiter in hardware which prevents simultaneous access of these registers by the host software, i.e. the driver. There is a hardware bug in the aribter that signals a host access of the registers later than it actually happens. A write of the Transmit or Receive Descriptor Tail register could result in an incorrect value if the driver and ME perform simultaneous accesses which could result in an access to an invalid memory address. This would return an Unsupported Request which could hang the hardware. Workaround the issue by checking the FWSM register bit24 which is set by ME before it accesses the MAC CSR registers.

* | e1000e: Spurious interrupts & dropped packets with 82577/8/9 in half-duplexBruce Allan2011-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 82577/8/9 in half-duplex when a received packet is passed from the PHY to the MAC, if too many preamble octects are stripped from the packet before arriving at the MAC, it can be misintrepeted as an in-band message rather than an actual frame. For example, if the frame contents resembled an interrupt request in-band message, it would trigger a false interrupt. In most cases, the packet is just dropped. By reducing the number of preamble octets stripped from the beginning of the frame when passing it from the PHY to the MAC, the MAC will interpret the frame properly. An additional uses of the magic PHY_REG(770, 16) have been updated with a define introduced with this patch.

Finally, we need to perform the null check after trying to update the beacon, or else beacons will never be sent after a single mapping failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As this discussion pointed out http://marc.info/?l=linux-netdev&m=131257225602375 netdevices that are based on serial line disciplines should use netif_rx_ni() when pushing received socketbuffers into the netdev rx queue. Following commit 614851601c121b1320a35757ab88292d6272f906 ("slip: fix NOHZ local_softirq_pending 08 warning") this patch updates the slcan driver accordingly.

* | dp83640: increase receive time stamp buffer sizeRichard Cochran2011-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The dp83640 buffers receive time stamps from special PHY status frames, matching them to received PTP packets in a work queue. Because the timeout for orphaned time stamps is so long and the buffer is so small, the driver can drop time stamps under moderate PTP traffic. This commit fixes the issue by decreasing the timeout to (at least) one timer tick and increasing the buffer size.

* | gianfar: fix fiper alignment after resetting the timeRichard Cochran2011-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After resetting the time, the PPS signals on the FIPER output channels are incorrectly offset from the clock time, as can be readily verified by a looping back the FIPER to the external time stamp input. Despite its name, setting the "Fiper Realignment Disable" bit seems to fix the problem, at least on the P2020. Also, following the example code from the Freescale BSP, it is not really necessary to disable and re-enable the timer in order to reprogram the FIPER. (The documentation is rather unclear on this point. It seems that writing to the alarm register also disables the FIPER.)
