| * net: systemport: Fix missing Wake-on-LAN interrupt for SYSTEMPORT LiteFlorian Fainelli2017-06-021-2/+5
| | | | | | | | | | | | | | | | | | | | | | On SYSTEMPORT Lite, since we have the main interrupt source in the first cell, the second cell is the Wake-on-LAN interrupt, yet the code was not properly updated to fetch the second cell, and instead looked at the third and non-existing cell for Wake-on-LAN.

| * bnx2x: Fix Multi-CosMintz, Yuval2017-06-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently multi-cos isn't working for bnx2x quite some time - driver implements ndo_select_queue() to allow queue-selection for FCoE, but the regular L2 flow would cause it to modulo the fallback's result by the number of queues. The fallback would return a queue matching the needed tc [via __skb_tx_hash()], but since the modulo is by the number of TSS queues where number of TCs is not accounted, transmission would always be done by a queue configured into using TC0.

* | bnxt_en: Fix xmit_more with BQL.Michael Chan2017-05-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | We need to write the doorbell if BQL has stopped the queue and skb->xmit_more is set. Otherwise it is possible for the tx queue to rot and cause tx timeout. Fixes: 4d172f21cefe ("bnxt_en: Implement xmit_more.")

| | | | | | | | | | | | | | | | | | | | In the existing code, the local variable sh is hardcoded to true to calculate default rings for shared ring configuration.

* | bnxt_en: Optimize doorbell write operations for newer chips.Michael Chan2017-05-304-21/+23
| | | | | | | | | | | | | | | | | | | | | | Older chips require the doorbells to be written twice, but newer chips do not. Add a new common function bnxt_db_write() to write all doorbells appropriately depending on the chip. Eliminating the extra doorbell on newer chips has a significant performance improvement on pktgen. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

Aligning the size of rx buffers will ensure that page_frag_alloc() returns aligned addresses. This can be reproduced on PPC by setting the network MTU to 1450 (or other non-multiple-of-4) and then generating sufficient inbound network traffic (one or two large "wget"s usually does it), producing the following oops: Unable to handle kernel paging request for unaligned access at address 0xc00000ffc43af656 Faulting instruction address: 0xc00000000080ef8c Oops: Kernel access of bad area, sig: 7 [#1] SMP NR_CPUS=2048 NUMA PowerNV Modules linked in: vmx_crypto powernv_rng rng_core powernv_op_panel leds_powernv led_class nfsd ip_tables x_tables autofs4 xfs lpfc bnx2x mdio libcrc32c crc_t10dif crct10dif_generic crct10dif_common CPU: 104 PID: 0 Comm: swapper/104 Not tainted 4.11.0-rc8-00088-g4c761da #2 task: c00000ffd4892400 task.stack: c00000ffd4920000 NIP: c00000000080ef8c LR: c00000000080eee8 CTR: c0000000001f8320 REGS: c00000ffffc33710 TRAP: 0600 Not tainted (4.11.0-rc8-00088-g4c761da) MSR: 9000000000009033 <SF,HV,EE,ME,IR,DR,RI,LE> CR: 24082042 XER: 00000000 CFAR: c00000000080eea0 DAR: c00000ffc43af656 DSISR: 00000000 SOFTE: 1 GPR00: c000000000907f64 c00000ffffc33990 c000000000dd3b00 c00000ffcaf22100 GPR04: c00000ffcaf22e00 0000000000000000 0000000000000000 0000000000000000 GPR08: 0000000000b80008 c00000ffc43af636 c00000ffc43af656 0000000000000000 GPR12: c0000000001f6f00 c00000000fe1a000 000000000000049f 000000000000c51f GPR16: 00000000ffffef33 0000000000000000 0000000000008a43 0000000000000001 GPR20: c00000ffc58a90c0 0000000000000000 000000000000dd86 0000000000000000 GPR24: c000007fd0ed10c0 00000000ffffffff 0000000000000158 000000000000014a GPR28: c00000ffc43af010 c00000ffc9144000 c00000ffcaf22e00 c00000ffcaf22100 NIP [c00000000080ef8c] __skb_clone+0xdc/0x140 LR [c00000000080eee8] __skb_clone+0x38/0x140 Call Trace: [c00000ffffc33990] [c00000000080fb74] skb_clone+0x74/0x110 (unreliable) [c00000ffffc339c0] [c000000000907f64] packet_rcv+0x144/0x510 [c00000ffffc33a40] [c000000000827b64] __netif_receive_skb_core+0x5b4/0xd80 [c00000ffffc33b00] [c00000000082b2bc] netif_receive_skb_internal+0x2c/0xc0 [c00000ffffc33b40] [c00000000082c49c] napi_gro_receive+0x11c/0x260 [c00000ffffc33b80] [d000000066483d68] bnx2x_poll+0xcf8/0x17b0 [bnx2x] [c00000ffffc33d00] [c00000000082babc] net_rx_action+0x31c/0x480 [c00000ffffc33e10] [c0000000000d5a44] __do_softirq+0x164/0x3d0 [c00000ffffc33f00] [c0000000000d60a8] irq_exit+0x108/0x120 [c00000ffffc33f20] [c000000000015b98] __do_irq+0x98/0x200 [c00000ffffc33f90] [c000000000027f14] call_do_irq+0x14/0x24 [c00000ffd4923a90] [c000000000015d94] do_IRQ+0x94/0x110 [c00000ffd4923ae0] [c000000000008d90] hardware_interrupt_common+0x150/0x160 Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Net device reset can fail when the h/w or f/w is in a bad state. Subsequent netdevice open fails in bnxt_hwrm_stat_ctx_alloc(). The cleanup invokes bnxt_hwrm_resource_free() which inturn calls bnxt_disable_int(). In this routine, the code segment if (ring->fw_ring_id != INVALID_HW_RING_ID) BNXT_CP_DB(cpr->cp_doorbell, cpr->cp_raw_cons); results in NULL pointer dereference as cpr->cp_doorbell is not yet initialized, and fw_ring_id is zero. The fix is to initialize cpr fw_ring_id to INVALID_HW_RING_ID before bnxt_init_chip() is invoked.

| | | | | | | | | | | | | | | | | | | | The current code enables up to the maximum MSIX vectors in the PCIE config space without considering the max completion rings available.
