| | | | | | | | | | | | | We disable VxLAN offload when more than 1 UDP port is added to the driver, since Skyhawk doesn't support offload with multiple ports. The existing driver design expects the user to delete all port configurations and create a configuration with a single UDP port for VxLAN offload to be re-enabled. Remove this restriction by tracking the ports added and re-enabling offload when ports get deleted and only 1 port is left.

* be2net: Support UE recovery in BEx/Skyhawk adaptersSriharsha Basavapatna2016-09-071-2/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch supports recovery from UEs caused due to Transient Parity Errors (TPE), in BE2, BE3 and Skyhawk adapters. This change avoids system reboot when such errors occur. The driver recovers from these errors such that the adapter resumes full operational status as prior to the UE. Following is the list of changes in the driver to support this: o The driver registers its UE recoverable capability with ARM FW at init time. This also allows the driver to know if the feature is supported in the FW. o As the UE recovery requires precise time bound processing, the driver creates its own error recovery work queue with a single worker thread (per module, shared across functions). o Each function runs an error detection task at an interval of 1 second as required by the FW. The error detection logic already exists for BEx/SH, but it now runs in the context of a separate worker thread. o When an error is detected by the task, if it is recoverable, the PF0 driver instance initiates a soft reset, while other PF driver instances wait for the reset to complete and the chip to become ready. Once the chip is ready, all driver instances including PF0, resume to reinitialize the respective functions. o The PF0 driver checks for some recovery criteria, to determine if the recovery can be initiated. If the criteria is not met, the PF0 driver does not initiate a soft reset, it retains the existing behavior to stop further processing and requires a reboot to get the chip to operational state again. o To allow each function to share the workq, while also making progress in its recovery process, a per-function recovery state machine is used. The per-function tasks avoid blocking operations like msleep() while in this state machine (until reinit state) and instead reschedule for the required delay. o With these changes, the existing error recovery code for Lancer also runs in the context of the new worker thread.

* be2net: replace polling with sleeping in the FW completion pathSathya Perla2016-08-081-1/+18
| | | | | | | | | | | | | | | | | | | | The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with BHs disabled. The driver currently issues the required cmds to the FW in these contexts and polls on completions from the FW, while BHs remain disabled. This can cause either packet loss or packet reception to be delayed on that CPU. This patch defers processing of the above cmds to a separate workqueue. With this change, FW cmds are now issued only in process context. Now that the FW cmds are issued only in process context, they can sleep waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock) calls are now replaced with mutex calls. Also a new rx_filter_lock is now needed to protect the RX filtering fields like vids[] between be_vlan_add/rem_vid() and __be_set_rx_mode() contexts.

* be2net: Avoid unnecessary firmware updates of multicast listSriharsha Basavapatna2016-08-081-0/+2
| | | | | | | | | | | | | | | Eachtime the ndo_set_rx_mode() routine is called, the driver programs the multicast list in the adapter without checking if there are any changes to the list. This leads to a flood of RX_FILTER cmds when a number of vlan interfaces are configured over the device, as the ndo_ gets called for each vlan interface. To avoid this, we now use __dev_mc_sync() and __dev_uc_sync() API, but only to detect if there is a change in the mc/uc lists. Now that we use this API, the code has to be-designed to issue these API calls for each invocation of the be_set_rx_mode() call.

| | | | | | | | | | | | | | | | Currently, we do not distribute queue resources to enable RSS for VFs in multi-channel/partition configurations. Fix this by having each PF(SRIOV capable) calculate it's share of the 15 RSS Policy Tables available per port before provisioning resources for all the VFs. This proportional share calculation is done based on division of the PF's MAX VFs with the Total MAX VFs on that port. It also needs to learn about the no: of NIC PFs on the port and subtract that from the 15 RSS Policy Tables on the port.

This is because when the TXULP pulls the TX WRB to check the length of the frame to be transmitted it also adds the size of VLANs to be inserted by the HW to the length of the frame indicated in the WRB, which in some cases fails the range check.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently Dough Ledford reported a deadlock happening between ocrdma-load sequence and NetworkManager service issueing "open" on be2net interface. The deadlock happens when any be2net hook (e.g. open/close) is called in parallel to insmod ocrdma.ko. A. be2net is sending administrative open/close event to ocrdma holding device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net. So sequence of locks is rtnl_lock---> device_list lock B. When new ocrdma roce device gets registered, infiniband stack now takes rtnl_lock in ib_register_device() in GID initialization routines. So sequence of locks in this path is device_list lock ---> rtnl_lock. This improper locking sequence causes deadlock. In order to resolve the above deadlock condition, ocrdma intorduced a patch to stop listening to administrative open/close events generated from be2net driver. It now depends on link-state-change async-event generated from CNA. This change leaves behind dead code which used to generate administrative open/close events. This patch cleans-up all that dead code from be2net.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 72ef3a88fa8e ("be2net: set pci_func_num while issuing GET_PROFILE_CONFIG cmd") passed a specific pf_num while issuing a GET_PROFILE_CONFIG cmd as FW returns descriptors for all functions when pf_num is zero. But, when pf_num is set to a non-zero value, FW does not return the Port resource descriptor. This patch fixes this by setting pf_num to 0 while issuing the query cmd and adds code to pick the correct NIC resource descriptor from the list of descriptors returned by FW.

|/ | | | | | | | | | | This patch removes a line of code that changes adapter->recommended_prio value followed by yet another assignment. Also, the variable is used to store the vlan priority value that is already shifted to the PCP bits position in the vlan tag format. Hence, the name of this variable is changed to recommended_prio_bits. Signed-off-by: Sathya Perla <sathya.perla@avagotech.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* be2net: set pci_func_num while issuing GET_PROFILE_CONFIG cmdSomnath Kotur2015-10-131-0/+1
| | | | | | | | | | | | | | The FW requires the pf_num field in the cmd hdr to be set for it to return the specific function's descriptors in the GET_PROFILE_CONFIG cmd. If not set, the FW returns the descriptors of all the functions on the device. If the first descriptor is not what is being queried for, the driver will read wrong data. This patch fixes this issue by using the GET_CNTL_ATTRIB cmd to query the real pci_func_num of a function and then uses it in the GET_PROFILE_CONFIG cmd.

* be2net: Support for OS2BMC.Venkata Duvvuru2015-05-141-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | OS2BMC feature will allow the server to communicate with the on-board BMC/idrac (Baseboard Management Controller) over the LOM via standard Ethernet. When OS2BMC feature is enabled, the LOM will filter traffic coming from the host. If the destination MAC address matches the iDRAC MAC address, it will forward the packet to the NC-SI side band interface for iDRAC processing. Otherwise, it would send it out on the wire to the external network. Broadcast and multicast packets are sent on the side-band NC-SI channel and on the wire as well. Some of the packet filters are not supported in the NIC and hence driver will identify such packets and will hint the NIC to send those packets to the BMC. This is done by duplicating packets on the management ring. Packets are sent to the management ring, by setting mgmt bit in the wrb header. The NIC will forward the packets on the management ring to the BMC through the side-band NC-SI channel.

When an error (related to HW or FW) is detected on a function, the driver must pro-actively report a "link down" to the stack so that a possible failover can be initiated. This is being done currently only for some HW errors. This patch reports a "link down" even for fatal FW errors and EEH errors.
