While probing BGX we requesting appropriate QLM for it's configuration and get LMAC count by that request. Then, while reading configured MAC values from SSDT table we need to save them in proper mapping: BGX[i]->lmac[j].mac = <MAC value> to later provide for initialization stuff. In order to fill such mapping properly we need to add lmac index to be used while acpi initialization since at this moment bgx->lmac_count already contains actual value. Signed-off-by:

Fix a minor fallout from the merge of the timers and the networking trees. The following error may result if the PTP_1588_CLOCK prerequisites are not available: drivers/built-in.o: In function `ptp_clock_unregister': (.text+0x40e0a5): undefined reference to `pps_unregister_source' drivers/built-in.o: In function `ptp_clock_unregister': (.text+0x40e0cc): undefined reference to `posix_clock_unregister' drivers/built-in.o: In function `ptp_clock_event': (.text+0x40e249): undefined reference to `pps_event' drivers/built-in.o: In function `ptp_clock_register': (.text+0x40e5e1): undefined reference to `pps_register_source' drivers/built-in.o: In function `ptp_clock_register': (.text+0x40e62c): undefined reference to `posix_clock_register' drivers/built-in.o: In function `ptp_clock_register': (.text+0x40e68d): undefined reference to `pps_unregister_source' Signed-off-by:

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. Signed-off-by:

On 80xx only one lane of DLM0 and DLM1 (of BGX0) can be used , so even though lmac count may be 2 but LMAC1 should use serdes lane of DLM1. Since it's not possible to distinguish 80xx from 81xx as PCI devid are same, this patch adds this config support by replying on what firmware configures the lmacs with. Signed-off-by:

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:

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:

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. Signed-off-by:

In order to break the hard dependency between the PTP clock subsystem and ethernet drivers capable of being clock providers, this patch provides simple PTP stub functions to allow linkage of those drivers into the kernel even when the PTP subsystem is configured out. Drivers must be ready to accept NULL from ptp_clock_register() in that case. And to make it possible for PTP to be configured out, the select statement in those driver's Kconfig menu entries is converted to the new "imply" statement. This way the PTP subsystem may have Kconfig dependencies of its own, such as POSIX_TIMERS, without having to make those ethernet drivers unavailable if POSIX timers are cconfigured out. And when support for POSIX timers is selected again then the default config option for PTP clock support will automatically be adjusted accordingly. The pch_gbe driver is a bit special as it relies on extra code in drivers/ptp/ptp_pch.c. Therefore we let the make process descend into drivers/ptp/ even if PTP_1588_CLOCK is unselected.
