This restores the original behaviour before the block callbacks were introduced. Allow the drivers to do binding of block always, no matter if the NETIF_F_HW_TC feature is on or off. Move the check to the block callback which is called for rule insertion.

Add support to create hash (exact-match) filters based on the value of 'hash' field in ch_filter_specification. Allocate SMT/L2T entries if DMAC-rewrite/SMAC-rewrite is requested. Allocate CLIP entry in case of IPv6 filter. Use cpl_act_open_req[6] to send hash filter create request to hw. Also, the filter tuple is calculated as part of sending this request. Hash-filter reply is processed on getting cpl_act_open_rpl. In case of success, various bits/fields in filter-tcb are set per filter requirement, such as enabling filter hitcnts, and/or various header rewrite operations, such as VLAN-rewrite, NAT or (L3/L4)-rewrite, and SMAC/DMAC-rewrite. In case of failure, clear the filter entry and release any hw resources occupied by it.

Two functions were always used to set the DMA addresses in Tx descriptors, because this address is split into a base+offset in the descriptors. A mask was used to come up with the base and offset addresses and two functions were called, mvpp2_txdesc_dma_addr_set() and mvpp2_txdesc_offset_set(). This patch moves the base+offset calculation logic to mvpp2_txdesc_dma_addr_set(), and removes mvpp2_txdesc_offset_set() to simplify things.

Too many TSO descriptors can be required for the default queue size, when using small MSS values for example. Prevent this by adding a maximum number of allowed TSO segments (300).

The ASIC has the ability to generate events whenever a sensor indicates the temperature goes above or below its high or low thresholds, respectively. In new firmware versions the firmware enforces a minimum of 5 degrees Celsius difference between both thresholds. Make the driver conform to this requirement. Note that this is required even when the events are disabled, as in certain systems interrupts are generated via GPIO based on these thresholds.

Note that FIB entries are no longer being offloaded to this device. This patch reworks FIB rule handling to return a message to the user: $ ip ru add pref 99 from all to 8.8.8.8 table 11 Error: spectrum: FIB rules not supported. Aborting offload. spectrum currently only checks whether the fib rule is a default rule or an l3mdev rule, both of which it knows how to handle. Any other it aborts FIB offload. Move the processing to check the rule type inline with the user request. If the rule is an unsupported one, then a work queue entry is used to abort the offload. Change the rule delete handling to just return since it does nothing at the moment.

the verifier got progressively smarter over time and size of its internal state grew as well. Time to reduce the memory consumption. Before: sizeof(struct bpf_verifier_state) = 6520 After: sizeof(struct bpf_verifier_state) = 896 It's done by observing that majority of BPF programs use little to no stack whereas verifier kept all of 512 stack slots ready always. Instead dynamically reallocate struct verifier state when stack access is detected. Runtime difference before vs after is within a noise. The number of processed instructions stays the same.
