* net: thunderx: Fix transmit queue timeout issueSunil Goutham2016-12-023-37/+54
| | | | | | | | | | | | | | | | | | Transmit queue timeout issue is seen in two cases - Due to a race condition btw setting stop_queue at xmit() and checking for stopped_queue in NAPI poll routine, at times transmission from a SQ comes to a halt. This is fixed by using barriers and also added a check for SQ free descriptors, incase SQ is stopped and there are only CQE_RX i.e no CQE_TX. - Contrary to an assumption, a HW errata where HW doesn't stop transmission even though there are not enough CQEs available for a CQE_TX is not fixed in T88 pass 2.x. This results in a Qset error with 'CQ_WR_FULL' stalling transmission. This is fixed by adjusting RXQ's RED levels for CQ level such that there is always enough space left for CQE_TXs.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the following 1. When interface is being teardown and queues are being cleaned up, free pending SKBs that are in SQ which are either not transmitted or freed as NAPI is disabled by that time. 2. While interface initialization, delay CFG_DONE notification till the end to avoid corner cases where TXQs are enabled but CQ interrupts are not which results blocking transmission and kicking off watchdog. 3. Check for IFF_UP while re-enabling RBDR interrupts from tasklet. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes multiple issues 1. Convert all driver statistics to percpu counters for accuracy. 2. To avoid multiple CQEs posted by a TSO packet appended to HW, TSO pkt's SQE has 'post_cqe' not set but a dummy SQE is added for getting HW transmit completion notification. This dummy SQE has 'dont_send' set and HW drops the pkt pointed to in this thus Tx drop counter increases. This patch fixes this by subtracting SW tx tso counter from HW Tx drop counter for actual packet drop counter. 3. Reset all individual queue's and VNIC HW stats when interface is going down. 4. Getrid off unnecessary counters in hot path. 5. Bringout all CQE error stats i.e both Rx and Tx. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Programming LMAC credits taking 9K frame size by default is incorrect as for an interface which is one of the many on the same BGX/QLM no of credits available will be less as Tx FIFO will be divided across all interfaces. So let's say a BGX with 40G interface and another BGX with multiple 10G, bandwidth of 10G interfaces will be effected when traffic is running on both 40G and 10G interfaces simultaneously. This patch fixes this issue by programming credits based on netdev's MTU. Also fixed configuring MTU to HW and added CQE counter for pkts which exceed this value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ThunderX 88xx pass 2.x chips when TSO is offloaded to HW, HW posts a CQE for every TSO segment transmitted. Current code does handles this, but is prone to issues when segment sizes are small resulting in SW processing too many CQEs and also at times frees a SKB which is not yet transmitted. This patch handles the errata in a different way and eliminates issues with earlier approach, TSO packet is submitted to HW with post_cqe=0, so that no CQE is posted upon completion of transmission of TSO packet but a additional HDR + IMMEDIATE descriptors are added to SQ due to which a CQE is posted and will have required info to be used while cleanup in napi.
