22560 devices tfd queue max size is 2^16. Allow a configurable max size in the driver for supporting different devices. Signed-off-by:

Nowadays, the tfd queue max size is 2^8, and the reserved size in the command header sequence field for the tfd entry index is 8 bits, allowing an injective function from the hw pointers to the tfd entry index in the sequence field. In 22560 devices the tfd queue max size is 2^16, meaning that the hw pointers are 16 bit long (allowing to point to each entry in the tfd queue). However, the reserved space in the sequence field for the tfd entry doesn't change, and we are limited to 8 bit. This requires cancelling the injective function from hw pointer to tfd entry in the sequence number. Use iwl_pcie_get_cmd_index to wrap the hw pointer's to the n_window size, which is maximum 256 in tx queues, and so, keep the injective function between the window wrapped hw pointers to tfd entry index in the sequence.

In 22560 devices the ROM sendis an interrupt to the host once the IML reading is done. Handle this interrupt, and indicate sw error in case the value is fail. Additionally, the cause for sw error in 22560 devices have been changed, so update the cause list. Signed-off-by:

For devices which use the image loader image, the length of the frame must be updated in the byte count in bytes, and not dwords as today. Avoid dividing the input length by 4. Signed-off-by:

Context information structure was added to 22000 devices for firmware self init. In the next generation of devices the context information changes significantly, and the original context information is divided roughly to three data structures: context information gen3, prph information and prph scratch. In addition, the init flow changes so the firmware is loaded by the IML, and so we must allocate the IML on the DRAM and give the ROM the IML's address before kicking the firmware's self init.

The hw now refers to two new blocks: * rx tr tail - The Tail index on the free buffers queue TR, which is update by the device after reading the free buffer from the tr. * rx cr tail - Updated by the driver when completing processing a new completion descriptor in the cr. Add these two new struct to the rxq, allocate and free them when needed. In addition, the register for rx write pointer had been changed to HBUS_TARG_WRPTR. The way to differentiate tx from rx is the queue number. TX range is 0-511, and RX's is 512-527. Signed-off-by:

Different device families may have different flag values for passing a message to the fw (i.e. SW_RESET). In order to keep the code readable, and avoid conditioning upon the family, store a value for each flag, which indicates the bit that needs to be enabled. Additionally, support 22560 device csr flags and addresses. Signed-off-by:

Skbprio (SKB Priority Queue) is a queueing discipline that prioritizes packets according to their skb->priority field. Under congestion, already-enqueued lower priority packets will be dropped to make space available for higher priority packets. Skbprio was conceived as a solution for denial-of-service defenses that need to route packets with different priorities as a means to overcome DoS attacks. v5 *Do not reference qdisc_dev(sch)->tx_queue_len for setting limit. Instead set default sch->limit to 64. v4 *Drop Documentation/networking/sch_skbprio.txt doc file to move it to tc man page for Skbprio, in iproute2. v3 *Drop max_limit parameter in struct skbprio_sched_data and instead use sch->limit. *Reference qdisc_dev(sch)->tx_queue_len only once, during initialisation for qdisc (previously being referenced every time qdisc changes). *Move qdisc's detailed description from in-code to Documentation/networking. *When qdisc is saturated, enqueue incoming packet first before dequeueing lowest priority packet in queue - improves usage of call stack registers. *Introduce and use overlimit stat to keep track of number of dropped packets. v2 *Use skb->priority field rather than DS field. Rename queueing discipline as SKB Priority Queue (previously Gatekeeper Priority Queue). *Queueing discipline is made classful to expose Skbprio's internal priority queues. Signed-off-by:

Certain PHY's have issues when operating in GBit slave mode and can be forced to master mode. Examples are RTL8211C, also the Micrel PHY driver has a DT setting to force master mode. If two such chips are link partners the autonegotiation will fail. Standard defines a self-clearing on read, latched-high bit to indicate this error. Check this bit to inform the user. Signed-off-by:

The cited patch added a call to dev_change_tx_queue_len in SIOCSIFTXQLEN case. This obsoletes the new len comparison check done before the function call. Remove it here. For the desicion of keep/remove the negative value check, we examine the range check in dev_change_tx_queue_len. On 64-bit we will fail with -ERANGE. The 32-bit int ifr_qlen will be sign extended to 64-bits when it is passed into dev_change_tx_queue_len(). And then for negative values this test triggers: if (new_len != (unsigned int)new_len) return -ERANGE; because: if (0xffffffffWHATEVER != 0x00000000WHATEVER) On 32-bit the signed value will be accepted, changing behavior. Therefore, the negative value check is kept. Fixes: 3f76df19 ("net: use dev_change_tx_queue_len() for SIOCSIFTXQLEN") Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Add extack messages for tc flower Nir says: This patch set adds extack messages support to tc flower part of mlxsw. The messages provide clear reasoning to failures, as some of the available actions and keys are not supported in driver or HW and resources may get exhausted. The first patch deals with propagation of the extack pointer among the functions dealing with key parsing and action sets handling. Following patches 2-4 add appropriate messages across the different layers of mlxsw tc flower implementation. ==================== Signed-off-by:
