2011-08-02bnx2x: Prevent restarting Tx during bnx2x_nic_unloadVladislav Zolotarov
Tx queues were stopped before bp->state was changed to a value different from BNX2X_STATE_OPEN, which allowed the bnx2x_tx_int() called from the NAPI context to re-enable it. This then allowed the netdev->ndo_start_xmit() to be called in the middle of the function reset and rings freeing. This patch changes bp->state to a value different from BNX2X_STATE_OPEN BEFORE disabling the Tx queues in order to restore the broken protection against the above race in the bnx2x_tx_int().

2011-07-21bnx2x: Broken self-test in SF mode on 578xxVladislav Zolotarov
This patch fixes both the failure in the self-test on 578xx and a hole in a parity recovery flow that this failure has discovered: - internal 'pending' state in a VLAN_MAC object wasn't been cleared when the object state change was called with DRV_ONLY flag, which in particular happens when a parity error happens during the self-test. - bp->sp_state wasn't cleared in the similar circumstances as described above.

2011-07-14bnx2x: Multiple concurrent l2 traffic classesAriel Elior
Overview: Support mapping of priorities to traffic classes and traffic classes to transmission queues ranges in the net device. The queue ranges are (count, offset) pairs relating to the txq array. This can be done via DCBX negotiation or by kernel. As a result Enhanced Transmission Selection (ETS) and Priority Flow Control (PFC) are supported between L2 network traffic classes. Mapping: This patch uses the netdev_set_num_tc, netdev_set_prio_tc_map and netdev_set_tc_queue functions to map priorities to traffic classes and traffic classes to transmission queue ranges. This mapping is performed by bnx2x_setup_tc function which is connected to the ndo_setup_tc. This function is always called at nic load where by default it maps all priorities to tc 0, and it may also be called by the kernel or by the bnx2x upon DCBX negotiation to modify the mapping. rtnl lock: When the ndo_setup_tc is called at nic load or by kernel the rtnl lock is already taken. However, when DCBX negotiation takes place the lock is not taken. The work is therefore scheduled to be handled by the sp_rtnl task. Fastpath: The fastpath structure of the bnx2x which was previously used to hold the information of one tx queue and one rx queue was redesigned to represent multiple tx queues, one for each traffic class. The transmission queue supplied in the skb by the kernel can no longer be interpreted as a straightforward index into the fastpath structure array, but it must rather be decoded to the appropriate fastpath index and the tc within that fastpath. Slowpath: The bnx2x's queue object was redesigned to accommodate multiple transmission queues. The queue object's state machine was enhanced to allow opening multiple transmission-only connections on top of the regular tx-rx connection. Firmware: This feature relies on the tx-only queue feature introduced in the bnx2x 7.0.23 firmware and the FW likewise must have the bnx2x multi cos support.

Renaming the "reset_task" to a more general purpose name, "sp_rtnl_task", as it is already used for another purpose other than reset which is parity recovery, and since I plan to add a third operation for this task, updating the priority to traffic class and traffic class to transmission queues mappings after dcbx negotiation takes place.

2011-06-15New 7.0 FW: bnx2x, cnic, bnx2i, bnx2fcVlad Zolotarov
New FW/HSI (7.0): - Added support to 578xx chips - Improved HSI - much less driver's direct access to the FW internal memory needed. New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c): - Introduced chip dependent objects that have chip independent interfaces for configuration of MACs, multicast addresses, Rx mode, indirection table, fast path queues and function initialization/cleanup. - Objects functionality is based on the private function pointers, which allows not only a per-chip but also PF/VF differentiation while still preserving the same interface towards the driver. - Objects interface is not influenced by the HSI changes which do not require providing new parameters keeping the code outside the bnx2x_sp.c invariant with regard to such HSI chnages. Changes in a CNIC, bnx2fc and bnx2i modules due to the new HSI.

NIC partitioning is another flavor of multi function - having few PCI functions share the same physical port. Unlike the currently supported mode of multi-function which depends on the switch configuration and uses outer-VLAN, the NPAR mode is switch independent and uses the MAC addresses to distribute incoming packets to the different functions. This patch adds the specific HW setting of the NPAR mode and some distinctions between switch dependent (SD) and switch independent (SI) multi-function (MF) modes where the configuration is not the same.

2010-11-12bnx2x: Look inside vlan when determining checksum proto.Hao Zheng
Currently the skb->protocol field is used to setup checksum offloading on transmit for the correct protocol. However, if vlan offloading is disabled or otherwise not used, the protocol field will be ETH_P_8021Q, not the actual protocol. This will cause the checksum to be not computed correctly, even though the hardware is capable of looking inside vlan tags. Instead, look inside the header if necessary to determine the correct protocol type. To some extent this fixes a regression from 2.6.36 because it was previously not possible to disable vlan offloading and this error case was not exposed.
