This patch adds zero-copy Rx support for AF_XDP sockets. Instead of allocating buffers of type MEM_TYPE_PAGE_SHARED, the Rx frames are allocated as MEM_TYPE_ZERO_COPY when AF_XDP is enabled for a certain queue. All AF_XDP specific functions are added to a new file, i40e_xsk.c. Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS will allocate a new buffer and copy the zero-copy frame prior passing it to the kernel stack.

In this commit, the Rx path is refactored some, as a step torwards the introduction AF_XDP Rx zero-copy. The page re-use counter is moved into the i40e_reuse_rx_page, instead of bumping the counter in many places. The Rx buffer page clearing is moved for better readability. Lastely, functions to update statistics and bump the XDP Tx ring are introduced. Signed-off-by: NBjörn Töpel <bjorn.topel@intel.com> Signed-off-by: NAlexei Starovoitov <ast@kernel.org>

To enable easier FW distribution NFP can now automatically select between FW stored on the flash and loaded from the kernel. If FW loading policy is set to auto it will compare the versions of FW from the host and from the flash and load the newer one. If FW type doesn't match (e.g. one advanced application vs another) the FW from the host takes precedence, unless one of them is the basic NIC firmware, in which case the non-basic-NIC FW is selected. This automatic selection mechanism requires we inform user what the verdict was. Print a message to the logs explaining the decision and the reason.

There seems to be a problem in the x540's internal switch wherein if SR-IOV mode is enabled and an offloaded IPsec packet is sent to a local VF, the packet is silently dropped. This might never be a problem as it is somewhat a corner case, but if someone happens to be using IPsec offload from the PF to a VF that just happens to get migrated to the local box, communication will mysteriously fail. Not good. A simple way to protect from this is to simply not allow any IPsec offloads for outgoing packets when num_vfs != 0. This doesn't help any offloads that were created before SR-IOV was enabled, but we'll get to that later.

VLAN pruning is not valid when VLAN 0 is not active. If VLAN pruning is enabled and VLAN 0 is not active (8021q driver not loaded) then normal, non-VLAN, traffic will not pass. TX/RX VLAN pruning is enabled when the VLAN 0 is added to the active_vlan bitmap and it is disabled when VLAN 0 is removed from the active_vlan bitmap. So, only enable VLAN pruning when VLAN 0 is active. Setting RX VLAN pruning causes the switch to drop received VLAN packets when there are no matching VLAN ids in the associated VSI's switch filters. Setting TX pruning makes it so the switch will not send out any packets with VLAN tags that don't match the associated VSI's switch filters. With this patch, if the VF or PF tries to send a VLAN tagged packet with a VLAN tag that it does not have a pruning rule for it will trigger an MDD event. For example, if PF0 has VLAN10 and VLAN11 interfaces and scapy is used to send a packet with VLAN8 then the MDD is triggered. Also make ice_vsi_kill_vlan return a value which the caller can check before updating VLAN related data structures (counts, pruning bits, etc.).

The value to be changed to is available as a netlink message which is parsed in this function.

When a malicious operation is detected, the firmware triggers an interrupt, which is then picked up by the service task (specifically by ice_handle_mdd_event). A reset is scheduled if required. Tx hang detection works in a similar way, except the logic here monitors the VSI's Tx queues and tries to revive them if stalled. If the hang is not resolved, the kernel eventually calls ndo_tx_timeout, which is handled by ice_tx_timeout.
