Jakub Kicinski says: ==================== This small series adds a feature which extends BPF offload beyond a pure host processing offload and firmly into the realm of heterogeneous processing. Allowing offloaded XDP programs to set the RX queue index opens the door for defining fully programmable RSS/n-tuple filter replacement. In fact the device datapath will skip the RSS processing completely if BPF decided on the queue already, making the XDP program replace part of the standard NIC datapath. We hope some day the entire NIC datapath will be defined by BPF :) ==================== Signed-off-by: NDaniel Borkmann <daniel@iogearbox.net> Acked-by: NAlexei Starovoitov <ast@kernel.org>

BPF has access to all internal FW datapath structures. Including the structure containing RX queue selection. With little coordination with the datapath we can let the offloaded BPF select the RX queue. We just need a way to tell the datapath that queue selection has already been done and it shouldn't overwrite it. Define a bit to tell datapath BPF already selected a queue (QSEL_SET), if the selected queue is not enabled (>= number of enabled queues) datapath will perform normal RSS. BPF queue selection on the NIC can be used to replace standard datapath RSS with fully programmable BPF/XDP RSS.

This patch gives an ID to each loaded BTF. The ID is allocated by the idr like the existing prog-id and map-id. The bpf_put(map->btf) is moved to __bpf_map_put() so that the userspace can stop seeing the BTF ID ASAP when the last BTF refcnt is gone. It also makes BTF accessible from userspace through the 1. new BPF_BTF_GET_FD_BY_ID command. It is limited to CAP_SYS_ADMIN which is inline with the BPF_BTF_LOAD cmd and the existing BPF_[MAP|PROG]_GET_FD_BY_ID cmd. 2. new btf_id (and btf_key_id + btf_value_id) in "struct bpf_map_info" Once the BTF ID handler is accessible from userspace, freeing a BTF object has to go through a rcu period. The BPF_BTF_GET_FD_BY_ID cmd can then be done under a rcu_read_lock() instead of taking spin_lock. [Note: A similar rcu usage can be done to the existing bpf_prog_get_fd_by_id() in a follow up patch] When processing the BPF_BTF_GET_FD_BY_ID cmd, refcount_inc_not_zero() is needed because the BTF object could be already in the rcu dead row . btf_get() is removed since its usage is currently limited to btf.c alone. refcount_inc() is used directly instead.

When computing the bitrate using values read from an SFP module EEPROM, we use the nominal BR plus BR,min and BR,max to determine the boundaries. But in some cases BR,min and BR,max aren't provided, which led the SFP code to end up having the nominal value for both the minimum and maximum bitrate values. When using a passive cable, the nominal value should be used as the maximum one, and there is no minimum one so we should use 0.

The current code already forwards the VF MAC address to the PF, except in one case. If the VF driver gets a valid MAC address from the firmware during probe time, it will not forward the MAC address to the PF, incorrectly assuming that the PF already knows the MAC address. This causes "ip link show" to show zero VF MAC addresses for this case. This assumption is not correct. Newer firmware remembers the VF MAC address last used by the VF and provides it to the VF driver during probe. So we need to always forward the VF MAC address to the PF. The forwarded MAC address may now be the PF assigned MAC address and so we need to make sure we approve it for this case.

For SFP+ modules, 0xA2 page is available only when Diagnostic Monitoring Type [Address A0h, Byte 92] is implemented. Extend bnxt_get_module_info(), to read optical diagnostics support at offset 92(0x5c) and set eeprom_len length to ETH_MODULE_SFF_8436_LEN (to exclude A2 page), if dianostics is not supported. Also in bnxt_get_module_info(), module id is read from offset 0x5e which is not correct. It was working by accident, as offset was not effective without setting enables flag in the firmware request. SFP module id is present at location 0. Fix this by removing the offset and read it from location 0.

A recent change to reduce delay granularity waiting for firmware reponse has caused a regression. With a tighter delay loop, the driver may see the beginning part of the response faster. The original 5 usec delay to wait for the rest of the message is not long enough and some messages are detected as invalid. Increase the maximum wait time from 5 usec to 20 usec. Also, fix the debug message that shows the total delay time for the response when the message times out. With the new logic, the delay time is not fixed per iteration of the loop, so we define a macro to show the total delay time.

When the core networking needs to detect the transport offset in a given packet and parse it explicitly, a full-blown flow_keys struct is used for storage. This patch introduces a smaller keys store, rework the basic flow dissect helper to use it, and apply this new helper where possible - namely in skb_probe_transport_header(). The used flow dissector data structures are renamed to match more closely the new role. The above gives ~50% performance improvement in micro benchmarking around skb_probe_transport_header() and ~30% around eth_get_headlen(), mostly due to the smaller memset. Small, but measurable improvement is measured also in macro benchmarking. v1 -> v2: use the new helper in eth_get_headlen() and skb_get_poff(), as per DaveM suggestion Suggested-by: NDavid Miller <davem@davemloft.net> Signed-off-by: NPaolo Abeni <pabeni@redhat.com> Signed-off-by: NDavid S.

`mf_mode' field indicates the multi-partitioning mode the device is configured to. This method doesn't scale very well, adding a new MF mode requires going over all the existing conditions, and deciding whether those are needed for the new mode or not. The patch defines a set of bit-fields for modes which are derived according to the mode info shared by the MFW and all the configuration would be made according to those. To add a new mode, there would be a single place where we'll need to go and choose which bits apply and which don't.
