Claudiu Manoil says: ==================== gianfar: Device configuration fixes This patchset represents the first part of an effort to solve some old device configuration issues in gianfar, especially run-time reset and re-configuration problems. I'm referring to "on-the-fly" configuration of registers against HW specification, concurrency issues during device reset / re-configuration operations, and implementing HW advisories for these operations. There's also a good deal of code cleanup and refactoring, and some other (minor) fixes as well. v2: Remove sysfs stubs w/o replacing them with module params (patch 2). ==================== Signed-off-by: -

gfar_clean_rx_ring() was designed to be called from napi (rx softirq) context to do the Rx processing. Calling it from a process context like this is a bug as it will clearly race with the napi Rx processing. There's also no point in initializing num_txbdfree since startup_gfar() already does that, when bringing the device up again (after reset). Changing num_txbdfree "on-the-fly" like this is also subject to race conditions. num_txbdfree is handled by the Tx processing path and the device reset procedure. Also, don't assume that num_rx_queues is always equal to num_tx_queues. Signed-off-by:

gfar_halt() and gfar_start() are responsible for stopping and starting the DMA and the Rx/Tx hw rings. They implement the support for the "graceful Rx/Tx stop/start" hw procedure, and also disable/enable eTSEC's hw interrupts in the process. The GRS/GTS procedure requires however to have the RQUEUE/TQUEUE registers cleared first and to wait for a period of time for the current frame to pass through the interface (around ~10ms for a jumbo frame). Only then may the GTS and GRS bits from DMACTRL be set to shut down the DMA, and finally the Tx_EN and Rx_EN bits in MACCFG1 may be cleared to disable the Tx/Rx blocks. The same register programming order applies to start the Rx/Tx: enabling the RQUEUE/TQUEUE *before* clearing the GRS/GTS bits. This is a HW recommendation in order to avoid a possible controller "lock up" during graceful reset. Cleanup the gfar_halt()/start() prototypes, to take priv instead of ndev as their purpose is to operate on HW. Enabling the RQUEUE/TQUEUE in the hw_init() is not needed anymore since that's the job of gfar_start(). Signed-off-by:

Throughout the code there are places where the controller's hw interrupt sources need to get disabled/enabled (masked/ un-masked) all at once. The recommendation for disabling the interrupts is to clear the ievent first then the imask register (not the other way around). Use the gfar_ints_enable/disable() helpers to make these operations consistent. Signed-off-by:

The RCTRL updates of the FSL_GIANFAR_DEV_HAS_PADDING device flag get overriden by the FSL_GIANFAR_DEV_HAS_TIMER flag settings, which impose a Rx padding alignment of 8 bytes. As all the eTSEC devices that set HAS_PADDING also set the HAS_TIMER flag, the HAS_PADDING flag is now obsolete. Signed-off-by:

Removing the sysfs stubs for the Tx FIFOCFG and ATTRELI (stashing) config registers, as these registers may only be configured after a MAC reset, with the controller stopped (i.e. during hw init, at probe() time). The current sysfs stubs allow on-the-fly updates of these registers (the locking measures are useless and only add unecessary code). Changing these registers is discouraged. Only the default values will be used instead. Moreover, the stashing (ATTRELI) configuration options were effectively disabled (didn't get to the hw anyway if changed) because the stashing device_flags (HAS_BD_STASHING|HAS_BUF_STASHING) were "accidentally" cleared during probe().

Factor out gfar_hw_init() to contain all the controller hw initialization steps for a better control of register writes, and to significantly simplify the tangled code from gfar_probe(). This results in code size and stack usage reduction (besides code readability). Fix memory leak on device removal, by freeing the rx_/tx_queue structures. Replace custom bit swapping function with a library one (bitrev8). Move allocation of rx_/tx_queue struct arrays before the group structure init, because in order to assign Rx/Tx queues to groups we need to have the queues first. This also allows earlier bail out of gfar_probe(), in case the memory allocation fails. The flow control checks for maccfg1 were removed from gfar_probe(), since flow control is disabled at probe time (priv->rx_/tx_pause_en are 0). Redundant initializations (by 0) also removed.

Phoebe Buckheister says: ==================== ieee802154: support rf212 and extended mac features this patch set adds support for the RF212 radio chip to the existing at86rf230 driver and adds support for numerous features of the RF212 chips to the ieee802154 stack. These features include CSMA parameter configuration, transmit power control, CCA parameter configuration, and automatic retransmission of frames. Netlink APIs are provided for all new options introduced in this set. Many features might also work for RF230, but since I have no such chips at my disposal, most new features are implemented only for RF212. Changes since v2: * Indentation Changes since v1: * CodingStyle compliance. Thanks Sergei Shtylyov * Add CSMA parameters to netlink phy list that were forgotten in v1 ==================== Signed-off-by: -

This patch does multiple things: * add .set_csma_params and .set_frame_retries for the RF212 radio. This should work fine with RF230, but since I have no RF230 radios to test with, RF230 does not implement these right now * enable TX_ARET for frame retransmission limits greater than -1 Since RF230 has no operations to change CSMA parameters or frame retry limits, RF230 will not be able to enter TX_ARET with this patch.

Introduce new netlink attributes for SET_PHY_ATTRS: * CSMA minimal backoff exponent * CSMA maximal backoff exponent * CSMA retry limit * frame retransmission limit The CSMA attributes shall correspond to minBE, maxBE and maxCSMABackoffs of 802.15.4, respectively. The frame retransmission shall correspond to maxFrameRetries of 802.15.4, unless given as -1: then the old behaviour of the stack shall apply. For RF2xy, the old behaviour is to not do channel sensing at all and simply send *right now*, which is not intended behaviour for most applications and actually prohibited for some channel/page combinations. For all values except frame retransmission limit, the defaults of 802.15.4 apply. Frame retransmission limits are set to -1 to indicate backward-compatible behaviour. Signed-off-by:
