2017-04-03qed: RoCE doesn't need to use SRCMintz, Yuval
As RoCE doesn't need to use the SRC, allocating ILT memory on behalf of RoCE is wasting available ILT lines. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-03qed: Correct TM ILT lines in presence of VFsMintz, Yuval
As of today there's no protocol supported that requires support from the TM hardware block and enables SRIOV, but we should still correct the calculation to reflect the lines required for such future VFs instead of changing the PF's own lines.

2017-04-03qed: Fix TM block ILT allocationMichal Kalderon
When configuring the HW timers block we should set the number of CIDs up until the last CID that require timers, instead of only those CIDs whose protocol needs timers support. Today, the protocols that require HW timers' support have their CIDs before any other protocol, but that would change in future [when we add iWARP support].

2017-04-03net: hns: Avoid Hip06 chip TX packet line buglipeng
There is a bug on Hip06 that tx ring interrupts packets count will be clear when drivers send data to tx ring, so that the tx packets count will never upgrade to packets line, and cause the interrupts engendered was delayed. Sometimes, it will cause sending performance lower than expected. To fix this bug, we set tx ring interrupts packets line to 1 forever, to avoid count clear. And set the gap time to 20us, to solve the problem that too many interrupts engendered when packets line is 1. This patch could advance the send performance on ARM from 6.6G to 9.37G when an iperf send thread on ARM and an iperf send thread on X86 for XGE.

2017-04-03net: hns: Fix to adjust buf_size of ring according to mtulipeng
Because buf_size of ring set to 2048, the process of rx_poll_one can reuse the page, therefore the performance of XGE can improve. But the chip only supports three bds in one package, so the max mtu is 6K when it sets to 2048. For better performane in litter mtu, we need change buf_size according to mtu. When user change mtu, hns is only change the desc in memory. There are some desc has been fetched by the chip, these desc can not be changed by the code. So it needs set the port loopback and send some packages to let the chip consumes the wrong desc and fetch new desc. Because the Pv660 do not support rss indirection, we need add version check in mtu change process.

After a new NAPI_STATE_MISSED state was added to NAPI we can get into this state and in such case we have to reschedule NAPI as some work is still pending and we have to process it. napi_complete_done() function returns false if we have to reschedule something (e.g. in case we were in MISSED state) as current polling have not been completed yet. nps_enet driver hasn't been verifying the return value of napi_complete_done() and has been forcibly enabling interrupts. That is not correct as we should not enable interrupts before we have processed all scheduled work. As a result we were getting trapped in interrupt hanlder chain as we had never been able to disabale ethernet interrupts again. So this patch makes nps_enet_poll() func verify return value of napi_complete_done() and enable interrupts only in case all scheduled work has been completed.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-03-29 This series contains updates to i40e and i40evf only. Preethi changes the default driver mode of operation to descriptor write-back for VF. Alex cleans up and addresses several issues in the way that i40e handles private flags. Modifies the driver to use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed. Refactors the driver by pulling the code responsible for fetching the receive buffer and synchronizing DMA into a single function. Also pulled the code responsible for handling buffer recycling and page counting and distributed it through several functions, so we can commonize the bits that handle either freeing or recycling the buffers. Cleans up the code in preparation for us adding support for build_skb(). Changed the way we handle the maximum frame size for the receive path so it is more consistent with other drivers. Paul enables XL722 to use the direct read/write method since it does not support the AQ command to read/write the control register. Christopher fixes a case where we miss an arq element if a new one is added before we enable interrupts and exit the loop. Jake cleans up a pointless goto statement. Also cleaned up a flag that was not being used. Carolyn does round 2 for adding a delay to the receive queue to accommodate the hardware needs. ==================== Signed-off-by: David S.

2017-03-29bnxt_en: Fix NULL pointer dereference in reopen failure pathSankar Patchineelam
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.
