* Fix netstat counters mapping in mlx5en(4).Hans Petter Selasky2019-05-081-26/+10
| | | | | | | | | | | | | | | | | The current mapping of driver counters to netstat counters is wrong. For example, a single jabber packet, will cause the Ierrs counter to count three times. The work for mapping the hardware and software counters to their right place in netstat counters were already done in Linux, take that as is to the FreeBSD driver.

| | | | | | | | | | | | | | ib_req_notify_cq may return negative value which will indicate a failure. In the case of uncorrectable error, we will end up in an endless loop. Fix that, by going to another loop with poll_more only if there is anything left to poll.

| | | | | | | | | | | | | | | | | | | | | | | | | Today mlx5 devices support two teardown modes: 1- Regular teardown 2- Force teardown This change introduces the enhanced version of the "Force teardown" that allows SW to perform teardown in a faster way without the need to reclaim all the pages. Fast teardown provides the following advantages: 1- Fix a FW race condition that could cause command timeout 2- Avoid moving to polling mode 3- Close the vport to prevent PCI ACK to be sent without been scattered to memory Linux commit: fcd29ad17c6ff885dfae58f557e9323941e63ba2 MFC after: 3 days Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=347268

* Configure firmware to use RX hash format in mini CQE in mlx5en(4).Hans Petter Selasky2019-05-082-5/+12
| | | | | | | | | | | | | | | | | | | | When using CQE zipping, one can choose between RX hash and Checksum. This will indicate the parameter on which a zipping session should be stopped. While porting the Linux code, Checksum was chosen. However, the value of Checksum is not being used anywhere. For the FreeBSD driver, we prefer to use the RX hash format which will guarantee the RX hash value for all the mini CQEs. While at it, make sure to initialize the Checksum value in the decompressed CQE. Submitted by: slavash@ MFC after: 3 days Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=347264

The counter between resets is reset by request for reset, and not by a successful reset. The interval between two resets can be configured via sysctl: hw.mlx5.sw_reset_timeout which is global to all mlx5 devices in the system.

* Correctly define the interface state bits in mlx5en(4).Hans Petter Selasky2019-05-082-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | While at it remove unused interface state bits. This also fixes and issue during shutdown: There is an issue where the firmware fails during mlx5_load_one, the health_care timer detects the issue and schedules a health_care call. Then the mlx5_load_one detects the issue, cleans up and quits. Then the health_care starts and calls mlx5_unload_one to clean up the resources that no longer exist and causes kernel panic. The root cause is that the bit MLX5_INTERFACE_STATE_DOWN is not set after mlx5_load_one fails. The solution is removing the bit MLX5_INTERFACE_STATE_DOWN and quit mlx5_unload_one if the bit MLX5_INTERFACE_STATE_UP is not set. The bit MLX5_INTERFACE_STATE_DOWN is redundant and we can use MLX5_INTERFACE_STATE_UP instead.

* tun/tap: merge and rename to `tuntap`Kyle Evans2019-05-0831-2387/+1786
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tun(4) and tap(4) share the same general management interface and have a lot in common. Bugs exist in tap(4) that have been fixed in tun(4), and vice-versa. Let's reduce the maintenance requirements by merging them together and using flags to differentiate between the three interface types (tun, tap, vmnet). This fixes a couple of tap(4)/vmnet(4) issues right out of the gate: - tap devices may no longer be destroyed while they're open [0] - VIMAGE issues already addressed in tun by kp [0] emaste had removed an easy-panic-button in r240938 due to devdrn blocking. A naive glance over this leads me to believe that this isn't quite complete -- destroy_devl will only block while executing d_* functions, but doesn't block the device from being destroyed while a process has it open. The latter is the intent of the condvar in tun, so this is "fixed" (for certain definitions of the word -- it wasn't really broken in tap, it just wasn't quite ideal). ifconfig(8) also grew the ability to map an interface name to a kld, so that `ifconfig {tun,tap}0` can continue to autoload the correct module, and `ifconfig vmnet0 create` will now autoload the correct module. This is a low overhead addition. (MFC commentary) This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this, and how critical they are. Changes after this are likely easily MFC'd without taking this merge, but the merge will be easier. I have no plans to do this MFC as of now.

* Remove non-functional SCTP checksum offload support for virtio.Michael Tuexen2019-05-072-11/+2
| | | | | | | | | | | | | | | | | | | | | | Checksum offloading for SCTP is not currently specified for virtio. If the hypervisor announces checksum offloading support, it means TCP and UDP checksum offload. If an SCTP packet is sent and the host announced checksum offload support, the hypervisor inserts the IP checksum (16-bit) at the correct offset, but this is not the right checksum, which is a CRC32c. This results in all outgoing packets having the wrong checksum and therefore breaking SCTP based communications. This patch removes SCTP checksum offloading support from the virtio network interface. Thanks to Felix Weinrank for making me aware of the issue. Reviewed by: bryanv@ MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D20147 Notes: svn path=/head/; revision=347233
