Currently when we noticed a HW ECC error we would request the use reload the driver to force a reset of the part.

The commit 8fad346f366a7 ("eee802154: add basic support for RF212 to at86rf230 driver") introduced the new function is_rf212() with some minor issues in declaration: 1) Fix the function type by changing it to bool as the function definition returns a boolean value. Additionally both callers of is_rf212() are expected to return a boolean value. 2) Fix the function specifier by deleting the inline keyword as the compiler takes care of that.

2014-02-25gianfar: Fix Tx int miss, dont write IC on-the-flyClaudiu Manoil
Programming the interrupt coalescing (IC) registers while the controller/DMA is on may incur the loss of one Tx confirmation interrupt, under certain conditions. This is a subtle hw race because it does not occur during a burst of Tx packets. It has been observed on p2020 devices that, if just one packet is being xmit'ed, the Tx confirmation doesn't trigger and BQL evetually blocks the Tx queues, followed by Tx timeout and an un-responsive device. This issue was not apparent prior to introducing BQL support, as a late Tx confirmation was not an issue back then and the next burst of Tx frames would have triggered the Tx confirmation/ Tx ring cleanup anyway. Bottom line, the hw specifications state that the IC registers should not be programmed while the Rx/Tx blocks (the DMA) are enabled. Further more, these registers are currently re-written with the same values on the processing path, over and over again. To fix this, rewriting the IC registers has been removed from the processing path (napi poll). A complete MAC reset procedure has been implemented for the ethtool -c option instead, to reliably update these registers while the controller is stopped.

2014-02-25gianfar: Fix device reset races (oops) for TxClaudiu Manoil
The device reset procedure, stop_gfar()/startup_gfar(), has concurrency issues. "Kernel access of bad area" oopses show up during Tx timeout device reset or other reset cases (like changing MTU) that happen while the interface still has traffic. The oopses happen in start_xmit and clean_tx_ring when accessing tx_queue-> tx_skbuff which is NULL. The race comes from de-allocating the tx_skbuff while transmission and napi processing are still active. Though the Tx queues get temoprarily stopped when Tx timeout occurs, they get re-enabled as a result of Tx congestion handling inside the napi context (see clean_tx_ring()). Not disabling the napi during reset is also a bug, because clean_tx_ring() will try to access tx_skbuff while it is being de-alloc'ed and re-alloc'ed. To fix this, stop_gfar() needs to disable napi processing after stopping the Tx queues. However, in order to prevent clean_tx_ring() to re-enable the Tx queue before the napi gets disabled, the device state DOWN has been introduced. It prevents the Tx congestion management from re-enabling the de-congested Tx queue while the device is brought down. An additional locking state, RESETTING, has been introduced to prevent simultaneous resets or to prevent configuring the device while it is resetting. The bogus 'rxlock's (for each Rx queue) have been removed since their purpose is not justified, as they don't prevent nor are suited to prevent device reset/reconfig races (such as this one).

2014-02-25gianfar: Don't free/request irqs on device resetClaudiu Manoil
Resetting the device (stop_gfar()/startup_gfar()) should be fast and to the point, in order to timely recover from an error condition (like Tx timeout) or during device reconfig. The irq free/ request routines are just redundant here, and they should be part of the device close/ open routines instead.

2014-02-25gianfar: Fix on-the-fly vlan and mtu updatesClaudiu Manoil
The RCTRL and TCTRL registers should not be changed on-the-fly, while the controller is running, otherwise unexpected behaviour occurs. But that's exactly what gfar_vlan_mode() does, updating the VLAN acceleration bits inside RCTRL/TCTRL. The attempt to lock these operations doesn't help, but only adds to the confusion. There's also a dependency for Rx FCB insertion (activating /de-activating the TOE offload block on Rx) which might change the required rx buffer size. This makes matters worse as gfar_vlan_mode() ends up calling gfar_change_mtu(), though the MTU size remains the same. Note that there are other situations that may affect the required rx buffer size, like changing RXCSUM or rx hw timestamping, but errorneously the rx buffer size is not recomputed/ updated in the process. To fix this, do the vlan updates properly inside the MAC reset and reconfiguration procedure, which takes care of the rx buffer size dependecy and the rx TOE block (PRSDEP) activation/deactivation as well (in the correct order). As a consequence, MTU/ rx buff size updates are done now by the same MAC reset and reconfig procedure, so that out of context updates to MAXFRM, MRBLR, and MACCFG inside change_mtu() are no longer needed. The rx buffer size dependecy to Rx FCB is now handled for the other cases too (RXCSUM and rx hw timestamping). Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-02-25gianfar: Implement MAC reset and reconfig procedureClaudiu Manoil
The main MAC config registers like: RCTRL/TCTRL, MRBLR, MAXFRM, RXIC/TXIC, most fields of MACCFG1/2, should not be changed on-the-fly, but at least after stopping the DMA and disabling the Rx/Tx blocks and, for increased reliability, after a MAC soft reset. Impelement a complete MAC soft reset and reconfig procedure following the latest HW advisories - gfar_mac_reset() - to replace gfar_mac_init() and (the confusing) init_registers() functions. Factor out separate config functions for RCTRL and TCTRL, insure programming order of the relevant config regs after MAC soft reset. Split gfar_hw_init() into gfar_mac_reset() and the remaining global regs that don't need to be reconfigured after MAC soft reset (FIFOCFG, ATTRELI, HW counters a.s.o). As gfar_hw_init() now makes all the register writes @probe() time, based on all the device flags and config options, it must be moved further down, just before register_netdev(), as the last config step when the config values are comitted to HW. Also, move netif_carrier_off() after register_netdev(), because it has no effect if called before. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S.

2014-02-25loopback: sctp: add NETIF_F_SCTP_CSUM to device featuresDaniel Borkmann
Drivers are allowed to set NETIF_F_SCTP_CSUM if they have hardware crc32c checksumming support for the SCTP protocol. Currently, NETIF_F_SCTP_CSUM flag is available in igb, ixgbe, i40e/i40evf drivers and for vlan devices. If we don't have NETIF_F_SCTP_CSUM then crc32c is done through CPU instructions, invoked from crypto layer, or if not available as slow-path fallback in software. Currently, loopback device propagates checksum offloading feature flags in dev->features, but is missing SCTP checksum offloading. Therefore, account for NETIF_F_SCTP_CSUM as well.

2014-02-24net/mlx4: Fix limiting number of IRQ's instead of RSS queuesIdo Shamay
This fix a performance bug introduced by commit 90b1ebe "mlx4: set maximal number of default RSS queues", which limits the numbers of IRQs opened by core module. The limit should be on the number of queues in the indirection table - rx_rings, and not on the number of IRQ's. Also, limiting on mlx4_core initialization instead of in mlx4_en, prevented using "ethtool -L" to utilize all the CPU's, when performance mode is prefered, since limiting this number to 8 reduces overall packet rate by 15%-50% in multiple TCP streams applications. For example, after running ethtool -L <ethx> rx 16 Packet rate Before the fix 897799 After the fix 1142070 Results were obtained using netperf: S=200 ; ( for i in $(seq 1 $S) ; do ( \ netperf -H 11.7.13.55 -t TCP_RR -l 30 &) ; \ wait ; done | grep "1 1" | awk '{SUM+=$6} END {print SUM}' ) CC: Yuval Mintz <yuvalmin@broadcom.com> Signed-off-by: Ido Shamay <idos@mellanox.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.
