Add support for half-duplex 100M and 10M copper connections by parsing the advertisment results rather than trying to decode the negotiated speed from one of the PHYs "vendor" registers. This allows us to decode the duplex as well, which means we can support half-duplex mode for the slower speeds.

Add a helper to convert the result of the autonegotiation advertisment into the PHYs speed and duplex settings. If the result is full duplex, also extract the pause mode settings from the link partner advertisment.

A mechanism for detection of stuck Rx/Tx rings due to missed or misrouted interrupts. Check if there are unhandled completion descriptors before the first MSI-X interrupt arrived. The check is per queue and per interrupt vector. Once such condition is detected, driver and device reset is scheduled. Signed-off-by: Netanel Belgazal <netanel@amazon.com> Signed-off-by: David S.

This version fixes net/dccp/trace.h to avoid sparse warning.

Add SCTP ACK tracking trace event to trace the changes of SCTP association state in response to incoming packets. It is used for debugging SCTP congestion control algorithms, and will replace sctp_probe module. Note that this event a bit tricky. Since this consists of 2 events (sctp_probe and sctp_probe_path) so you have to enable both events as below. # cd /sys/kernel/debug/tracing # echo 1 > events/sctp/sctp_probe/enable # echo 1 > events/sctp/sctp_probe_path/enable Or, you can enable all the events under sctp. # echo 1 > events/sctp/enable Since sctp_probe_path event is always invoked from sctp_probe event, you can not see any output if you only enable sctp_probe_path.

The changes are mostly in qed, and include changes in the FW interface files, as well as updating the FW initialization and debug collection code. The protocol drivers have minor functional changes for this firmware. Patch 1 Rearranges and refactors the FW interface files in preparation of the new FW (no functional change). Patch 2 Prepares the code for support of new HW (no functional change). Patch 3 Actual utilization of the new FW. Patch 4 Advances drivers' version. v3->v4: Fix a compilation issue which was reported by krobot (dependency on CRC8). v2->v3: Resend the series with a fixed title in the cover letter. v1->v2: - Break the previous single patch into several patches. - Fix compilation issues which were reported by krobot. ==================== Signed-off-by: David S.

inet_diag currently provides less/greater than or equal operators for comparing ports when filtering sockets. An equal comparison can be performed by combining the two existing operators, or a user can for example request a port range and then do the final filtering in userspace. However, these approaches both have drawbacks. Implementing equal using LE/GE causes the size and complexity of a filter to grow quickly as the number of ports increase, while it on busy machines would be great if the kernel only returns information about relevant sockets. This patch introduces source and destination port equal operators. INET_DIAG_BC_S_EQ is used to match a source port, INET_DIAG_BC_D_EQ a destination port, and usage is the same as for the existing port operators. I.e., the port to match is stored in the no-member of the next inet_diag_bc_op-struct in the filter. Signed-off-by: Kristian Evensen <kristian.evensen@gmail.com> Signed-off-by: David S.

When dev_requeue_skb() is called with bulked skb list, only the first skb of the list will be requeued to qdisc layer, and leak the others without free them.

Address/port initialization should work correctly regardless of the order in which command line arguments are supplied, E.g, cfg_port should be used to connect to the remote host even if it is processed after -D, src/dst address initialization should not require that [-4|-6] be specified before the -S or -D args, receiver should be able to bind to *.<cfg_port> Achieve this by making sure that the address/port structures are initialized after all command line options are parsed. Store cfg_port in host-byte order, and use htons() to set up the sin_port/sin6_port before bind/connect, so that the network system calls get the correct values in network-byte order.

Update the offload flag, TCQ_F_OFFLOADED, in each dump call (and ignore the offloading function return value in relation to this flag). This is done because a qdisc is being initialized, and therefore offloaded before being grafted. Since the ability of the driver to offload the qdisc depends on its location, a qdisc can be offloaded and un-offloaded by graft calls, that doesn't effect the qdisc itself.

When running consumer and/or producer operations and empty checks in parallel its possible to have the empty check run past the end of the array. The scenario occurs when an empty check is run while __ptr_ring_discard_one() is in progress. Specifically after the consumer_head is incremented but before (consumer_head >= ring_size) check is made and the consumer head is zeroe'd. To resolve this, without having to rework how consumer/producer ops work on the array, simply add an extra dummy slot to the end of the array. Even if we did a rework to avoid the extra slot it looks like the normal case checks would suffer some so best to just allocate an extra pointer.
