Some busy bits are available in the global register 1, such as the ATU Busy bit. We may want to use this function to wait for them to change, so add a new parameter to mv88e6352_wait() instead of hard-coding REG_GLOBAL2. In the meantime, since the REG_READ() macro already checks for error, remove the redundant check for ret < 0.

In commit 5a7baa78 ("bonding: Advertize vxlan offload features when supported"), Or Gerlitz added support conditional vxlan offload. In this patch I also add support for all kind of tunnels, but we allow a bonding device to not require segmentation, as it is always better to make this segmentation at the very last stage, if a particular slave device requires it. Tested: Setup a GRE tunnel, on a physical NIC not having tx-gre-segmentation. Results on bnx2x are even better, as we no longer have to segment in software. ethtool -K bond0 tx-gre-segmentation off super_netperf 50 --google-pacing-rate 30000000 -H 10.7.8.152 -l 15 7538.32 ethtool -K bond0 tx-gre-segmentation on super_netperf 50 --google-pacing-rate 30000000 -H 10.7.8.152 -l 15 10200.5 Signed-off-by: NEric Dumazet <edumazet@google.com> Cc: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: NDavid S.

fixed_phy_set_link_update() contains an early check against a NULL callback pointer, which basically prevents us from removing any previous callback we may have set.

When SRIOV commands are executed over the comm-channel and get a fatal error (e.g. timeout, closing command failure) the VF enters into error state and reset flow is activated. To be able to recognize whether the failure was on a closing command, the operational code for the given VHCR command is used. Once the device entered into an error state we prevent redundant error messages from being printed.

In SRIOV, both the PF and the VF may attempt device recovery whenever they assume that the device is not functioning. When the PF driver resets the device, the VF should detect this and attempt to reinitialize itself. The VF must be able to reset itself under all circumstances, even if the PF is not responsive. The VF shall reset itself in the following cases: 1. Commands are not processed within reasonable time over the communication channel. This is done considering device state and the correct return code based on the command as was done in the native mode, done in the next patch. 2. The VF driver receives an internal error event reported by the PF on the communication channel. This occurs when the PF driver resets the device or when VF is out of sync with the PF. Add 'VF reset' capability, which allows the VF to reinitialize itself even when the PF is not responsive. As PF and VF may run their reset flow simulantanisly, there are several cases that are handled: - Prevent freeing VF resources upon FLR, when PF is in its unloading stage. - Prevent PF getting VF commands before it has finished initializing its resources. - Upon VF startup, check that comm-channel is online before sending commands to the PF and getting timed-out.

We need to manage interface state to sync between reset flow and some other relative cases such as remove_one. This has to be done to prevent certain races. For example in case software stack is down as a result of unload call, the remove_one should skip the unload phase. Implement the remove_one case, handling AER and other cases comes next. The interface can be up/down, upon remove_one, the state will include an extra bit indicating that the device is cleaned-up, forcing other tasks to finish before the final cleanup.

We activate reset flow upon command fatal errors, when the device enters an erroneous state, and must be reset. The cases below are assumed to be fatal: FW command timed-out, an error from FW on closing commands, pci is offline when posting/pending a command. In those cases we place the device into an error state: chip is reset, pending commands are awakened and completed immediately. Subsequent commands will return immediately. The return code in the above cases will depend on the command. Commands which free and close resources will return success (because the chip was reset, so callers may safely free their kernel resources). Other commands will return -EIO. Since the device's state was marked as error, the catas poller will detect this and restart the device's software stack (as is done when a FW internal error is directly detected). The device state is protected by a persistent mutex lives on its mlx4_dev, as such no need any more for the hcr_mutex which is removed.

This includes: - resetting the chip when a fatal error is detected (the current code does not do this). - exposing the ability to enter error state from outside the catas code by calling its functionality.

In the vxlan transmit path there is no need to reference the socket for a tunnel which is needed for the receive side. We do, however, need the vxlan_dev flags. This patch eliminate references to the socket in the transmit path, and changes VXLAN_F_UNSHAREABLE to be VXLAN_F_RCV_FLAGS. This mask is used to store the flags applicable to receive (GBP, CSUM6_RX, and REMCSUM_RX) in the vxlan_sock flags. Signed-off-by: NTom Herbert <therbert@google.com> Signed-off-by: NDavid S.

The UDP tunnel transmit functions udp_tunnel_xmit_skb and udp_tunnel6_xmit_skb include a socket argument. The socket being passed to the functions (from VXLAN) is a UDP created for receive side. The only thing that the socket is used for in the transmit functions is to get the setting for checksum (enabled or zero). This patch removes the argument and and adds a nocheck argument for checksum setting. This eliminates the unnecessary dependency on a UDP socket for UDP tunnel transmit.
