Perform the priority check earlier in the function instead of repeating it for every action. This fixes a bug that allowed matchall rules with sample action to be added in front of flower rules on egress. Fixes: 54d0e963 ("mlxsw: spectrum_matchall: Add support for egress sampling") Signed-off-by:

Previous patch moved the protocol check out of the action check, so these if statements can now be converted to a switch statement. Perform the conversion. Signed-off-by:

The device HNAE3_DEVICE_VERSION_V3 supports up to 1280 queues and qsets for one function, so the bitwidth of tc_offset, meaning the tqps index, needs to expand from 10 bits to 11 bits. The device HNAE3_DEVICE_VERSION_V3 supports up to 512 queues on one TC. The tc_size, meaning the exponent with base 2 of queues supported on TC, which needs to expand from 3 bits to 4 bits.

The actual size on wire for tso skb should be (gso_segs - 1) * hdr + skb->len instead of skb->len, which can be seen by user using 'ethtool -S ethX' cmd, and 'Byte Queue Limit' also use the send size stat to do the queue limiting, so add send_bytes in the desc_cb to record the actual send size for a skb. And send_bytes is only for tx desc_cb and page_offset is only for rx desc, so reuse the same space for both of them. Signed-off-by:

Currently hns3 driver only handle the xmit skb with one level of fraglist skb, add handling for multi level by calling hns3_tx_bd_num() recursively when calculating bd num and calling hns3_fill_skb_to_desc() recursively when filling tx desc. When the skb has a fraglist level of 24, the skb is simply dropped and stats.max_recursion_level is added to record the error. Move the stat handling from hns3_nic_net_xmit() to hns3_nic_maybe_stop_tx() in order to handle different error stat and add the 'max_recursion_level' and 'hw_limitation' stat. Note that the max recursive level as 24 is chose according to below: commit 48a1df65 ("skbuff: return -EMSGSIZE in skb_to_sgvec to prevent overflow"). And that we are not able to find a testcase to verify the recursive fraglist case, so Fixes tag is not provided. Reported-by:

Currently, the queue reset process needs to be performed one by one, which is inefficient. However, the queue reset of the same function is always performed at the same time. Therefore, according to the UM, command HCLGE_OPC_CFG_RST_TRIGGER can be used to reset all queues of the same function at a time, in order to optimize the queue reset process. Signed-off-by:

Currently, if user hasn't change channel number, the rss_size is limited to be no more than the vector number, in order to keep one vector only being mapped to one queue. But the queue number of each tc can be different, and one vector also can be mapped by multiple queues. So remove this limitation. Signed-off-by:

The array size of bd_num_list is a fixed value, it may have potential overflow risk when array size of hclge_dfx_bd_offset_list is greater than that fixed value. So modify bd_num_list as a pointer and allocate memory for it according to array size of hclge_dfx_bd_offset_list. Signed-off-by:

Alex Elder says: ==================== net: ipa: a few last bits This series incorporates a few last things that didn't fit neatly with patches I've posted recently. The first patch eliminates all remaining kernel-doc warnings. There's still room for kernel-doc improvement, but at least what's there will no longer produce warnings. The next moves the definition of the value to store in the backward compatibility register (when present) into platform data files. The third removes two endpoint definitions that do not need to be defined. The next two switch the naming convention used for configuration data files to be based on the IPA version rather than the specific platform. I was skeptical about this at first (i.e., I thought a platform might have quirks separate from the IPA version). But I'm now convinced the IPA version is enough to define the details of the hardware block. If any exceptions to this are found, we can treat those differently. Note: these two patches produce warnings from checkpatch.pl about updating MAINTAINERS: these can be ignored. The sixth removes unnecessary checks for alignment of DMA memory allocations, based comments from David Laight. And the last removes a symbol representing the size of a table entry, using sizeof(__le64) in its place. ==================== Signed-off-by: -
Alex Elder authored
Entries in an IPA route or filter table are 64-bit little-endian addresses, each of which refers to a routing or filtering rule. The format of these table slots are fixed, but IPA_TABLE_ENTRY_SIZE is used to define their size. This symbol doesn't really add value, and I think it unnecessarily obscures what a table entry *is*. So get rid of IPA_TABLE_ENTRY_SIZE, and just use sizeof(__le64) in its place throughout the code. Update the comments in "ipa_table.c" to provide a little better explanation of these table slots.

A recent patch avoided doing 64-bit modulo operations by checking the alignment of some DMA allocations using only the lower 32 bits of the address. David Laight pointed out (after the fix was committed) that DMA allocations might already satisfy the alignment requirements. And he was right. Remove the alignment checks that occur after DMA allocation requests, and update comments to explain why the constraint is satisfied. The only place IPA_TABLE_ALIGN was used was to check the alignment; it is therefore no longer needed, so get rid of it. Add comments where GSI_RING_ELEMENT_SIZE and the tre_count and event_count channel data fields are defined to make explicit they are required to be powers of 2. Revise a comment in gsi_trans_pool_init_dma(), taking into account that dma_alloc_coherent() guarantees its result is aligned to a page size (or order thereof). Don't bother printing an error if a DMA allocation fails. Suggested-by:

Rename the SDM845 configuration data file so that its name is derived from its IPA version. I am not aware of any special IPA behavior or handling that would be based on a specific SoC (as opposed to a specific version of the IPA it contains).

We don't typically need much information about modem endpoints. Normally we need to specify information about modem endpoints in configuration data in only two cases: - When a modem TX endpoint supports filtering - When another endpoint's configuration refers to it For the first case, the AP initializes the filter table, and must know how many endpoints (AP and modem) support filtering. An example of the second case is the AP->modem TX endpoint, which defines the modem<-AP RX endpoint as its status endpoint. There is one exception to this, and it's due to a hardware quirk. For IPA v4.2 (only) there is a problem related to allocating GSI channels. And to work around this, the AP allocates *all* GSI channels at startup time--including those used by the modem. Get rid of the configuration information for two endpoints not required for the SDM845. SC7180 runs IPA v4.2, so we can't eliminate any modem endpoint definitions there. Two more minor changes: - Reorder the members defined for the ipa_endpoint_name enumerated type to match the order used in configuration data files when defining endpoints. - Add a new name, IPA_ENDPOINT_MODEM_DL_NLO_TX, which can be used for IPA v4.5+.
