* qede: Correctly map aggregation replacement pagesMintz, Yuval2016-11-03
| | | | | | | | | | | | | | | | | | | | | | Driver allocates replacement buffers before-hand to make sure whenever an aggregation begins there would be a replacement for the Rx buffers, as we can't release the buffer until aggregation is terminated and driver logic assumes the Rx rings are always full. For every other Rx page that's being allocated [I.e., regular] the page is being completely mapped while for the replacement buffers only the first portion of the page is being mapped. This means that: a. Once replacement buffer replenishes the regular Rx ring, assuming there's more than a single packet on page we'd post unmapped memory toward HW [assuming mapping is actually done in granularity smaller than page]. b. Unmaps are being done for the entire page, which is incorrect.

* qede: Fix statistics' strings for Tx/Rx queuesMintz, Yuval2016-10-31
| | | | | | | | | | | | | | | When an interface is configured to use Tx/Rx-only queues, the length of the statistics would be shortened to accomodate only the statistics required per-each queue, and the values would be provided accordingly. However, the strings provided would still contain both Tx and Rx strings for each one of the queues [regardless of its configuration], which might lead to out-of-bound access when filling the buffers as well as incorrect statistics presented.

* qede: Fix out-of-bound fastpath memory accessMintz, Yuval2016-10-29
| | | | | | | | | | | | | Driver allocates a shadow array for transmitted SKBs with X entries; That means valid indices are {0,...,X - 1}. [X == 8191] Problem is the driver also uses X as a mask for a producer/consumer in order to choose the right entry in the array which allows access to entry X which is out of bounds. To fix this, simply allocate X + 1 entries in the shadow array. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* qed*: Fix Kconfig dependencies with INFINIBAND_QEDRYuval Mintz2016-10-14
| | | | | | | | | | | | | | | | | | | | | The qedr driver would require a tristate Kconfig option [to allow it to compile as a module], and toward that end we've added the INFINIBAND_QEDR option. But as we've made the compilation of the qed/qede infrastructure required for RoCE dependent on the option we'd be facing linking difficulties in case that QED=y or QEDE=y, and INFINIBAND_QEDR=m. To resolve this, we seperate between the INFINIBAND_QEDR option and the infrastructure support in qed/qede by introducing a new QED_RDMA option which would be selected by INFINIBAND_QEDR but would be a boolean instead of a tristate; Following that, the qed/qede is fixed based on this new option so that all config combinations would be supported.

* net: Update API for VF vlan protocol 802.1ad supportMoshe Shemesh2016-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | Introduce new rtnl UAPI that exposes a list of vlans per VF, giving the ability for user-space application to specify it for the VF, as an option to support 802.1ad. We adjusted IP Link tool to support this option. For future use cases, the new UAPI supports multiple vlans. For now we limit the list size to a single vlan in kernel. Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward compatibility with older versions of IP Link tool. Add a vlan protocol parameter to the ndo_set_vf_vlan callback. We kept 802.1Q as the drivers' default vlan protocol. Suitable ip link tool command examples: Set vf vlan protocol 802.1ad: ip link set eth0 vf 1 vlan 100 proto 802.1ad Set vf to VST (802.1Q) mode: ip link set eth0 vf 1 vlan 100 proto 802.1Q Or by omitting the new parameter ip link set eth0 vf 1 vlan 100 Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver uses netif_tx_queue_stopped() to make sure the xmit_more indication will be honored, but that only checks for DRV_XOFF. At the same time, it's possible that during transmission the DQL will close the transmission queue with STACK_XOFF indication. In re-configuration flows, when the threshold is relatively low, it's possible that the device has no pending tranmissions, and during tranmission the driver would miss doorbelling the HW. Since there are no pending transmission, there will never be a Tx completion [and thus the DQL would not remove the STACK_XOFF indication], eventually causing the Tx queue to timeout. While we're at it - also doorbell in case driver has to close the transmission queue on its own [although this one is less important - if the ring is full, we're bound to receive completion eventually, which means the doorbell would only be postponed and not indefinetly blocked].

This rearranges the code so we bail out in either of the two cases and print a warning instead of accessing the uninitialized data. The qed_link_output structure remains untouched in this case, but all callers first call memset() on it, so at least we are not leaking stack data then. As discussed, we also use a compile-time check to ensure we never use any of the VF code if CONFIG_QED_SRIOV is disabled, and the PCI device table is updated to no longer bind to virtual functions in that configuration.

* | qed: Revisit chain implementationYuval Mintz2016-06-03
| | | | | | | | | | | | | | | | | | | | | | RoCE driver is going to need a 32-bit chain [current chain implementation for qed* currently supports only 16-bit producer/consumer chains]. This patch adds said support, as well as doing other slight tweaks and modifications to qed's chain API. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.

* | qed: Utilize FW 8.10.3.0Yuval Mintz2016-06-03
|/ | | | | | | | | | | | | | | The New QED firmware contains several fixes, including: - Wrong classification of packets in 4-port devices. - Anti-spoof interoperability with encapsulated packets. - Tx-switching of encapsulated packets. It also slightly improves Tx performance of the device. In addition, this firmware contains the necessary logic for supporting iscsi & rdma, for which we plan on pushing protocol drivers in the imminent future.

* qede: Don't expose self-test for VFsYuval Mintz2016-05-26
| | | | | | | | | | PFs and VFs differ in their registered ethtool operations, but they're using a common function for get_sset_count(). As a result, `ethtool -i' for a VF would indicate it supports selftest, although that's not the case. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.

* qede: Reload on GRO changesYuval Mintz2016-05-26
| | | | | | | | | | | | | Since driver is using a FW-based GRO implementation, this has some effects on its ability to cope with GRO enablement/disablement. As a result, driver must perform an inner-reload as a result of a state change in the offload configuration of said feature. [Failure to do so means network stack would continue to receive aggregated packets even though user requested the feature to be disabled].
