To allow better problem diagnosis the return codes for SMC-Dv2 are improved by this patch. A few more CLC DECLINE codes are defined and sent to the peer when an SMC connection cannot be established. There are now multiple SMC variations that are offered by the client and the server may encounter problems to initialize all of them. Because only one diagnosis code can be sent to the client the decision was made to send the first code that was encountered. Because the server tries the variations in the order of importance (SMC-Dv2, SMC-D, SMC-R) this makes sure that the diagnosis code of the most important variation is sent. v2: initialize rc in smc_listen_v2_check().

Subbaraya Sundeep says: ==================== Support for OcteonTx2 98xx silicon OcteonTx2 series of silicons have multiple variants, the 98xx variant has two network interface controllers (NIX blocks) each of which supports upto 100Gbps. Similarly 98xx supports two crypto blocks (CPT) to double the crypto performance. The current RVU drivers support a single NIX and CPT blocks, this patchset adds support for multiple blocks of same type to be active at the same time. Also the number of serdes controllers (CGX) have increased from three to five on 98xx. Each of the CGX block supports upto 4 physical interfaces depending on the serdes mode ie upto 20 physical interfaces. At a time each CGX block can be mapped to a single NIX. The HW configuration to map CGX and NIX blocks is done by firmware. NPC has two new interfaces added NIX1_RX and NIX1_TX similar to NIX0 interfaces. Also MCAM entries is increased from 4k to 16k. To support the 16k entries extended set is added in hardware which are at completely different register offsets. Fortunately new constant registers can be read to figure out the extended set is present or not. This patch set modifies existing AF and PF drivers in below order to support 98xx: - Prepare for supporting multiple blocks of same type. Functions which operate with block type to get or set resources count are modified to operate with block address - Manage allocating and freeing LFs from new NIX1 and CPT1 RVU blocks. - NIX block specific initialization and teardown for NIX1 - Based on the mapping set by Firmware, assign the NIX block LFs to a PF/VF. - Multicast entries context is setup for NIX1 along with NIX0 - NPC changes to support extended set of MCAM entries, counters and NIX1 interfaces to NPC. - All the mailbox changes required for the new blocks in 98xx. - Since there are more CGX links in 98xx the hardcoded LBK link value needed by netdev drivers is not sufficient any more. Hence AF consumers need to get the number of all links and calculate the LBK link. - Debugfs changes to display NIX1 contexts similar to NIX0 - Debugfs change to display mapping between CGX, NIX and PF. ==================== Link: https://lore.kernel.org/r/1603948549-781-1-git-send-email-sundeep.lkml@gmail.com Signed-off-by:

Unlike earlier silicon variants, OcteonTx2 98xx silicon has 2 NIX blocks and each of the CGX is mapped to either of the NIX blocks. Each NIX block supports 100G. Mapping btw NIX blocks and CGX is done by firmware based on CGX speed config to have a maximum possible network bandwidth. Since the mapping is not fixed, it's difficult for a user to figure out. Hence added a debugfs entry which displays mapping between CGX LMAC, NIX block and RVU PF. Sample result of this entry :: ~# cat /sys/kernel/debug/octeontx2/rvu_pf_cgx_map PCI dev RVU PF Func NIX block CGX LMAC 0002:02:00.0 0x400 NIX0 CGX0 LMAC0 Signed-off-by:

This patch puts together all mailbox changes for 98xx silicon: Attach -> Modify resource attach mailbox handler to request LFs from a block address out of multiple blocks of same type. If a PF/VF need LFs from two blocks of same type then attach mbox should be called twice. Example: struct rsrc_attach *attach; .. Allocate memory for message .. attach->cptlfs = 3; /* 3 LFs from CPT0 */ .. Send message .. .. Allocate memory for message .. attach->modify = 1; attach->cpt_blkaddr = BLKADDR_CPT1; attach->cptlfs = 2; /* 2 LFs from CPT1 */ .. Send message .. Detach -> Update detach mailbox and its handler to detach resources from CPT1 and NIX1 blocks. MSIX -> Updated the MSIX mailbox and its handler to return MSIX offsets for the new block CPT1. Free resources -> Update free_rsrc mailbox and its handler to return the free resources count of new blocks NIX1 and CPT1 Links -> Number of CGX,LBK and SDP links may vary between platforms. For example, in 98xx number of CGX and LBK links are more than 96xx. Hence the info about number of links present in hardware is useful for consumers to request link configuration properly. This patch sends this info in nix_lf_alloc_rsp. Signed-off-by:

The previous commit added support for IPA having up to six source and destination resources. But currently nothing uses more than four. (Five of each are used in a newer version of the hardware.) I find that in one of my build environments the compiler complains about newly-added code in two spots. Inspection shows that the warnings have no merit, but this compiler does not recognize that. ipa_main.c:457:39: warning: array index 5 is past the end of the array (which contains 4 elements) [-Warray-bounds] (and the same warning at line 483) We can make this warning go away by changing the number of elements in the source and destination resource limit arrays--now rather than waiting until we need it to support the newer hardware. This change was coming soon anyway; make it now to get rid of the warning. Signed-off-by:

Heiner Kallweit says: ==================== net: add functionality to net core byte/packet counters and use it in r8169 This series adds missing functionality to the net core handling of byte/packet counters and statistics. The extensions are then used to remove private rx/tx byte/packet counters in r8169 driver. ==================== Link: https://lore.kernel.org/r/1fdb8ecd-be0a-755d-1d92-c62ed8399e77@gmail.com Signed-off-by:

After switching to the net core rx/tx byte/packet counters we can remove the now unused private version. Signed-off-by:

Switch to the net core rx/tx byte/packet counter infrastructure. This simplifies the code, only small drawback is some memory overhead because we use just one queue, but allocate the counters per cpu. Signed-off-by:

We have netdev_alloc_pcpu_stats(), and we have devm_alloc_percpu(). Add a managed version of netdev_alloc_pcpu_stats, e.g. for allocating the per-cpu stats in the probe() callback of a driver. It needs to be a macro for dealing properly with the type argument. Signed-off-by:

Add dev_sw_netstats_tx_add(), complementing already existing dev_sw_netstats_rx_add(). Other than dev_sw_netstats_rx_add allow to pass the number of packets as function argument. Signed-off-by:
