This patch ensures that a command is not still in process before sending a new one to the device. This can happen when neard is in constant polling mode: the configure_hw command can be sent when neard restarts polling after a LLCP SYMM timeout but before the device has returned in timeout from the last DEP frame sent.

Once copied into the sk_buff data area using llcp_add_tlv(), the allocated TLVs must be freed. With this patch nfc_llcp_send_connect() and nfc_llcp_send_cc() don't return immediately on success and now free the allocated TLVs.

In functions using llcp_add_tlv(), a skb pointer could be set to NULL and then reuse afterward. With this patch, the skb pointer returned by llcp_add_tlv() is ignored since it can only be the passed skb pointer or NULL when the passed TLV is NULL. There is also no need to check for the TLV pointer as this is done by llcp_add_tlv().

With this complete rewrite, the loopback nfcsim driver now relies on the Digital layer of the nfc stack. As with the previous version, 2 nfc devices are declared when the driver is initialized. The driver supports the NFC_DEP protocol in NFC-A and NFC-F technologies. The 2 devices are using a pair of virtual links for sk_buff exchange. The out-link of one device is the in-link of the other and conversely. To receive data, a device calls nfcsim_link_recv_skb() on its in-link and waits for incoming data on a wait queue. To send data, a device calls nfcsim_link_send_skb() on its out-link which stores the passed skb and signals its wait queue. If the peer device was in the nfcsim_link_recv_skb() call, it will be signaled and will be able to pass the received sk_buff up to the Digital layer.

When setting the driver framing as NFC_DIGITAL_FRAMING_NFCF_NFC_DEP it used to be already configured as NFC_DIGITAL_FRAMING_NFCF which is the same. So this entry was empty in the in_protocols table. Now that the digital stack can handle PLS requests, it can be changed on the fly from NFC_DIGITAL_FRAMING_NFCA_NFC_DEP. This patch explicitly defines the framing configuration values for NFC_DIGITAL_FRAMING_NFCF_NFC_DEP.

It used to be EXPORTed, but then EXPORT usage was cleaned up (in 2012), without noticing that the function has no users at all (and curiously, never had any users). Delete it. While at it, remove non-static "inline" hints on nearby functions: these hints don't work across compilation units anyway, and these functions are not used in their .c file, thus they are never inlined. IOW: "inline" here does not help in any way.

ip2me: To instruct HW to send trapped ip2me traffic to kernel, we have to add this trap. Selection ip2me traffic is introduced later on in this set. ARPs: We are going to stop flooding to CPU port when netdev isn't bridged and only get packets destined to the netdev's IP address and certain control packets. Add traps for ARP request (broadcast) and response (unicast) in order to get these to the CPU and resolve neighbours. host miss: If a packet is routed through a directly connected route and its destination IP is not in the device's neighbour table, then we need to trap it to CPU. This will cause the host to resolve the MAC of the neighbour, which will be eventually programmed to the device's table. router ingress: In order to trap packets in router part.

When removing packet traps we should use action 'discard' instead of 'forward', as some trap IDs we'll add cannot be configured with the later. However, result is the same, as packets are not trapped to the CPU. In the future we will be able to reverse the operation properly by detaching the trap group from the CPU.

When enabling the router in the device we will represent L3 netdevs using router interfaces (RIFs). These will be specified whenever programming routes or neighbours on the netdev. Introduce the basic RIF infrastructure which allows one to lookup a RIF by its netdev. Later patches in the series will extend this, but the basic routines are needed now in order to direct traffic to CPU. Pointers to the RIF structs are stored in an array indexed by the RIF's number. This will allow us to efficiently update the kernel's neighbour table when regularly dumping the device's table.

During ports initialization a net device is registered for each available port, which implies the port is usable. However, a port is only usable after the different parts of the device (e.g. flooding, buffers) are initialized. This is especially important now, when we must initialize the router before the ports, as otherwise the device can't be initialized. Solve that by initializing the switch ports at the end of init sequence. Also, remove an unnecessary warning about port up/down events, which would otherwise be invoked whenever removing the driver, as ports are removed before unregistering the listener for these events.

We are going to assign router interfaces (RIFs) to netdevs if an IPv4 address was assigned to them. If one was assigned to a port netdev, this will translate to the PVID vPort being member in a RIF. While it's possible for a LAG slave to have an IP address, we can't have a vPort being member in two FIDs (assuming the LAG device will be put in bridge / assigned an IP address). Solve that by making the PVID vPort leave any FID it might be a member in when joining / leaving LAG. Note that the PVID vPort is the only vPort that can be present on the port when it's put under LAG.

When VLAN devices are created on top of LAG, their underlying vPorts are configured correctly with LAG membership. However, the PVID vPort is implicit and already present when the port netdev is put under LAG, so its LAG membership is never set. Set it correctly when joining / leaving LAG. This didn't matter until now, but we are going to introduce support for router interfaces (RIFs), which need to take into account LAG membership.

When port isn't bridged it is still possible to invoke switchdev ops and configure the device's VLAN filters. However, this will require us to use different Router InterFaces (RIFs) for the same netdev, instead of one per-netdev as with any other configuration. Taking the above into account and the fact that this functionality is questionable with regards to the device's normal use-case, remove it and instead return an error.

Port netdevs (e.g. swXpY) that are not bridged are represented in the device using a vPort with VID=PVID=1 (the PVID vPort), as untagged packets entering the switch are internally tagged with the PVID VLAN. When these packets are routed through a different port netdev they should egress untagged. This wasn't a problem until now, as non-bridged traffic only originated from the CPU, which transmits packets out of the port as-is. When a vPort is created with VID 1 mark it as egress untagged.

Calling the firmware to do function reset on the PF will kill all the VFs. To prevent that, we call function reset on the 1st PF open before any VF can be activated. On subsequent PF opens (with possibly some active VFs), a bit has been set and we'll skip the function reset. VF driver will always do function reset on every open. If there is an AER event, we will always do function reset. Signed-off-by: Michael Chan <michael.chan@broadocm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
