* Introduce LINUXKPI_GENSRCS.Konstantin Belousov2020-03-201-4/+3
| | | | | | | | | | | | | | Centralize the list of generated files required by linuxkpi consumers, into the common variable. This way, consumers that use the variable are insulated from possible changes in the list.

* Implement hardware TLS via send tags for mlx5en(4), which is supported byHans Petter Selasky2019-12-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ConnectX-6 DX. Currently TLS v1.2 and v1.3 with AES 128/256 crypto over TCP/IP (v4 and v6) is supported. A per PCI device UMA zone is used to manage the memory of the send tags. To optimize performance some crypto contexts may be cached by the UMA zone, until the UMA zone finishes the memory of the given send tag. An asynchronous task is used manage setup of the send tags towards the firmware. Most importantly setting the AES 128/256 bit pre-shared keys for the crypto context. Updating the state of the AES crypto engine and encrypting data, is all done in the fast path. Each send tag tracks the TCP sequence number in order to detect non-contiguous blocks of data, which may require a dump of prior unencrypted data, to restore the crypto state prior to wire transmission. Statistics counters have been added to count the amount of TLS data transmitted in total, and the amount of TLS data which has been dumped prior to transmission. When non-contiguous TCP sequence numbers are detected, the software needs to dump the beginning of the current TLS record up until the point of retransmission. All TLS counters utilize the counter(9) API. In order to enable hardware TLS offload the following sysctls must be set: kern.ipc.mb_use_ext_pgs=1 kern.ipc.tls.ifnet.permitted=1 kern.ipc.tls.enable=1 Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=355446

* Add support for hardware rate limiting to mlx5en(4).Hans Petter Selasky2018-05-291-1/+2
| | | | | | | | | | | | | | | | The hardware rate limiting feature is enabled by the RATELIMIT kernel option. Please refer to ifconfig(8) and the txrtlmt option and the SO_MAX_PACING_RATE set socket option for more information. This feature is compatible with hardware transmit send offload, TSO. A set of sysctl(8) knobs under dev.mce.<N>.rate_limit are provided to setup the ratelimit table and also to fine tune various rate limit related parameters.

* Switch to the new block based LRO input function for the mlx5enHans Petter Selasky2016-08-081-5/+4
| | | | | | | | | | | | | | | | driver. This change significantly increases the overall RX aggregation ratio for heavily loaded networks handling 10-80 thousand simultaneous connections. Remove the turbo LRO code and all references to it which has now been superceeded by the tcp_lro_queue_mbuf() function.

* Add mlx5 and mlx5en driver(s) for ConnectX-4 and ConnectX-4LX cardsHans Petter Selasky2015-11-101-0/+29
from Mellanox Technologies. The current driver supports ethernet speeds up to and including 100 GBit/s. Infiniband support will be done later. The code added is not compiled by default, which will be done by a separate commit. Sponsored by: Mellanox Technologies MFC after: 2 weeks Notes: svn path=/head/; revision=290650
