The hardware supports up to 8 TX BD for non-tso skb and up to 63 TX BD for TSO skb. Currently, the hns3 driver supports RX skb with fraglist when HW GRO is enabled, when the stack forwards a RX skb with fraglist, the stack need to linearize the skb before sending to other interface without TX fraglist support. This patch adds support for TX fraglist. The performance increases from 1 GByte to 1.5 GByte for one iperf TCP stream during forwarding test after this patch. BTW, the minimum BD number of ring should be updated to 72 for supporting TX fraglist.

2019-10-08tun: fix memory leak in error pathEric Dumazet1-2/+12
syzbot reported a warning [1] that triggered after recent Jiri patch. This exposes a bug that we hit already in the past (see commit ff244c6b29b1 ("tun: handle register_netdevice() failures properly") for details) tun uses priv->destructor without an ndo_init() method. register_netdevice() can return an error, but will not call priv->destructor() in some cases. Jiri recent patch added one more. A long term fix would be to transfer the initialization of what we destroy in ->destructor() in the ndo_init() This looks a bit risky given the complexity of tun driver. A simpler fix is to detect after the failed register_netdevice() if the tun_free_netdev() function was called already.

2019-10-08spi: Add a PTP system timestamp to the transfer structureVladimir Oltean2-0/+188
SPI is one of the interfaces used to access devices which have a POSIX clock driver (real time clocks, 1588 timers etc). The fact that the SPI bus is slow is not what the main problem is, but rather the fact that drivers don't take a constant amount of time in transferring data over SPI. When there is a high delay in the readout of time, there will be uncertainty in the value that has been read out of the peripheral. When that delay is constant, the uncertainty can at least be approximated with a certain accuracy which is fine more often than not. Timing jitter occurs all over in the kernel code, and is mainly caused by having to let go of the CPU for various reasons such as preemption, servicing interrupts, going to sleep, etc. Another major reason is CPU dynamic frequency scaling. It turns out that the problem of retrieving time from a SPI peripheral with high accuracy can be solved by the use of "PTP system timestamping" - a mechanism to correlate the time when the device has snapshotted its internal time counter with the Linux system time at that same moment. This is sufficient for having a precise time measurement - it is not necessary for the whole SPI transfer to be transmitted "as fast as possible", or "as low-jitter as possible". The system has to be low-jitter for a very short amount of time to be effective. This patch introduces a PTP system timestamping mechanism in struct spi_transfer. This is to be used by SPI device drivers when they need to know the exact time at which the underlying device's time was snapshotted. More often than not, SPI peripherals have a very exact timing for when their SPI-to-interconnect bridge issues a transaction for snapshotting and reading the time register, and that will be dependent on when the SPI-to-interconnect bridge figures out that this is what it should do, aka as soon as it sees byte N of the SPI transfer. Since spi_device drivers are the ones who'd know best how the peripheral behaves in this regard, expose a mechanism in spi_transfer which allows them to specify which word (or word range) from the transfer should be timestamped. Add a default implementation of the PTP system timestamping in the SPI core. This is not going to be satisfactory performance-wise, but should at least increase the likelihood that SPI device drivers will use PTP system timestamping in the future. There are 3 entry points from the core towards the SPI controller drivers: - transfer_one: The driver is passed individual spi_transfers to execute. This is the easiest to timestamp. - transfer_one_message: The core passes the driver an entire spi_message (a potential batch of spi_transfers). The core puts the same pre and post timestamp to all transfers within a message. This is not ideal, but nothing better can be done by default anyway, since the core has no insight into how the driver batches the transfers. - transfer: Like transfer_one_message, but for unqueued drivers (i.e. the driver implements its own queue scheduling).

Set channels callback enables the user to change the count of queues used by the driver using ethtool. We decided to currently support only equal number of rx and tx queues, this might change in the future. Also rename dev_up to dev_was_up in ena_update_queue_count() to make it clearer.

2019-10-07samples: pktgen: allow to specify destination IP range (CIDR)Daniel T. Lee10-12/+55
Currently, kernel pktgen has the feature to specify destination address range for sending packet. (e.g. pgset "dst_min/dst_max") But on samples, each pktgen script doesn't have any option to achieve this. This commit adds the feature to specify the destination address range with CIDR. -d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed # ./pktgen_sample01_simple.sh -6 -d fe80::20/126 -p 3000 -n 4 # tcpdump ip6 and udp 05:14:18.082285 IP6 fe80::99.71 > fe80::23.3000: UDP, length 16 05:14:18.082564 IP6 fe80::99.43 > fe80::23.3000: UDP, length 16 05:14:18.083366 IP6 fe80::99.107 > fe80::22.3000: UDP, length 16 05:14:18.083585 IP6 fe80::99.97 > fe80::21.3000: UDP, length 16 Signed-off-by: Daniel T.

2019-10-07samples: pktgen: fix proc_cmd command result check logicDaniel T. Lee1-6/+11
Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread', 'pg_set'. proc_cmd is designed to check command result with grep the "Result:", but this might fail since this string is only shown in 'pg_thread' and 'pg_set'. This commit fixes this logic by grep-ing the "Result:" string only when the command is not for 'pg_ctrl'. For clarity of an execution flow, 'errexit' flag has been set. To cleanup pktgen on exit, trap has been added for EXIT signal. Signed-off-by: Daniel T. Lee <danieltimlee@gmail.com> Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S.
