netdevice: add queue selection fallback handler for ndo_select_queue Add a new argument for ndo_select_queue() callback that passes a fallback handler. This gets invoked through netdev_pick_tx(); fallback handler is currently __netdev_pick_tx() as most drivers invoke this function within their customized implementation in case for skbs that don't need any special handling. This fallback handler can then be replaced on other call-sites with different queue selection methods (e.g. in packet sockets, pktgen etc). This also has the nice side-effect that __netdev_pick_tx() is then only invoked from netdev_pick_tx() and export of that function to modules can be undone. Suggested-by: David S.

net: core: explicitly select a txq before doing l2 forwarding Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

bnx2x: Revising locking scheme for MAC configuration On very rare occasions, repeated load/unload stress test in the presence of our storage driver (bnx2i/bnx2fc) causes a kernel panic in bnx2x code (NULL pointer dereference). Stack traces indicate the issue happens during MAC configuration; thorough code review showed that indeed several races exist in which one thread can iterate over the list of configured MACs while another deletes entries from the same list. This patch adds a varient on the single-writer/Multiple-reader lock mechanism - It utilizes an already exsiting bottom-half lock, using it so that Whenever a writer is unable to continue due to the existence of another writer/reader, it pends its request for future deliverance. The writer / last readers will check for the existence of such requests and perform them instead of the original initiator. This prevents the writer from having to sleep while waiting for the lock to be accessible, which might cause deadlocks given the locks already held by the writer. Another result of this patch is that setting of Rx Mode is now made in sleepable context - Setting of Rx Mode is made under a bottom-half lock, which was always nontrivial for the bnx2x driver, as the HW/FW configuration requires wait for completions. Since sleep was impossible (due to the sleepless-context), various mechanisms were utilized to prevent the calling thread from sleep, but the truth was that when the caller thread (i.e, the one calling ndo_set_rx_mode()) returned, the Rx mode was still not set in HW/FW. bnx2x_set_rx_mode() will now overtly schedule for the Rx changes to be configured by the sp_rtnl_task which hold the RTNL lock and is sleepable context.

bnx2x: Prevent NULL pointer dereference in kdump In scenarios in which a previous driver was removed without proper cleanup (e.g., kdump), it is possible for the chip to generate an interrupt without any apparent reason once interrupts are requested. Due to an erroneous initialization of resources, some of the bnx2x structs which are required for interrupt handling are initialized only after an interface's interrupt is requested from the OS. As a result, once such a spurious interrupt occurs, it will cause a NULL pointer dereference - the driver will access those structs in its interrupt handling routine. This patch change the interrupt request scheme so that bnx2x would only request interrupts from the kernel after it has finished initializing all the inner structs required for interrupt handling.

bnx2x: Segregate SR-IOV code In this patch the SR-IOV code is segregated from the main bulk of the bnx2x code. The CONFIG_BNX2X_SRIOV define is added to Broadcom's Kconfig, and allows the elision of the building of all the SR-IOV support code in the driver. The define is dependant on the kernel CONFIG_PCI_IOV configuration define. Signed-off-by: Ariel Elior <ariele@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

bnx2x: Support PF <-> VF Bulletin Board The PF <-> VF Bulletin Board is a simple interface between the PF and the VF. The main reason for the Bulletin Board is to allow the PF to be the initiator. The VF publishes at 'acquire' stage the GPA of a Bulletin Board structure it has allocated. The PF notes this GPA in the VF database. The VF samples the Bulletin Board periodically for new messages. The latest version of the BB is always used. Signed-off-by: Ariel Elior <ariele@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

bnx2x: Support of PF driver of a VF acquire request When a VF is probed by the VF driver, the VF driver sends an 'acquire' request over the VF <-> PF channel for the resources it needs to operate (interrupts, queues, etc). The PF driver either ratifies the request and allocates the resources, responds with the maximum values it will allow the VF to acquire, or fails the request entirely if there is a problem.

use FW 7.2.16 The patch integrates FW 7.2.16 HSI and implements driver part of GRO flow. FW 7.2.16 adds the ability to aggregate packets for GRO (and not just LRO) and also fixes some bugs. 1. Added new aggregation mode: GRO. In this mode packets are aggregated such that the original packets can be reconstructed by the OS. 2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32. 3. Adding the FCoE statistics structures to the BNX2X HSI. 4. Wrong configuration of TX HW input buffer size may cause theoretical performance effect. Performed configuration fix. 5. FCOE - Arrival of packets beyond task IO size can lead to crash. Fix firmware data-in flow. 6. iSCSI - In rare cases of on-chip termination the graceful termination timer hangs, and the termination doesn't complete. Firmware fix to MSL timer tolerance. 7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles open at the initiator side. Firmware implementation corrected to drop FIN received out-of-order or with isles still open. 8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes from the beginning of iSCSI PDU. Firmware implementation corrected to support arbitrary aligned retransmissions. 9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic might lead to crash. Firmware fix to relevant flow. Signed-off-by: Dmitry Kravkov <dmitry@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

bnx2x: consistent statistics after internal driver reload Currently bnx2x statistics are reset by inner driver reload, e.g. by MTU change. This patch fixes this issue - from now on statistics should only be reset upon device closure. Thanks to Michal Schmidt <mschmidt@redhat.com> for his initial patch regarding this issue.

bnx2x: Track active PFs with bitmap The recovery register (to which a hardware lock has been added in previous patch) is used amongst other things to track the active PFs. The old implementation which used a per path counter is not viable in a virtualized environment where a pf may increment the counter and then have the kernel crash around it preventing the counter from ever reaching zero. In the new implementation the scenario described will result in the PF timing out against the mcp, which will clear the PF's bit in the bitmask allowing recovery process to proceed.

bnx2x: Lock PF-common resources Use hardware locks to protect resources common to several Physical Functions. In a virtualized environment the RTNL lock only protects a PF's driver against the PFs sharing it's VMs with regard to device resources. Other PFs may reside in other VMs under other OSs, and are not subject to the lock. Such resources which were previously protected implicitly by the RTNL lock must now be protected explicitly with dedicated HW locks.

bnx2x: Support Queue Per Cos in 5771xx devices Enable the use of up to three hardware queues for transmission. The queues are always dequed round robin (i.e. strict priority, PFC and ETS are not supported). This does allow the allocation of a seperate HW queue for low volume, high priority traffic which will be serviced more promptly.

bnx2x: uses build_skb() in receive path bnx2x uses following formula to compute its rx_buf_sz : dev->mtu + 2*L1_CACHE_BYTES + 14 + 8 + 8 + 2 Then core network adds NET_SKB_PAD and SKB_DATA_ALIGN(sizeof(struct skb_shared_info)) Final allocated size for skb head on x86_64 (L1_CACHE_BYTES = 64, MTU=1500) : 2112 bytes : SLUB/SLAB round this to 4096 bytes. Since skb truesize is then bigger than SK_MEM_QUANTUM, we have lot of false sharing because of mem_reclaim in UDP stack. One possible way to half truesize is to reduce the need by 64 bytes (2112 -> 2048 bytes) Instead of allocating a full cache line at the end of packet for alignment, we can use the fact that skb_shared_info sits at the end of skb->head, and we can use this room, if we convert bnx2x to new build_skb() infrastructure. skb_shared_info will be initialized after hardware finished its transfert, so we can eventually overwrite the final padding. Using build_skb() also reduces cache line misses in the driver, since we use cache hot skb instead of cold ones. Number of in-flight sk_buff structures is lower, they are recycled while still hot.
