2021-01-21octeontx2-pf: Backport upstream kernel changesNaveen Mamindlapalli
Backported PF/VF changes from upstream kernel. -> Avoid modifying netdev->features dynamically by the driver. https://www.kernel.org/doc/html/latest/networking/netdev-features.html -> The MCAM entry allocation is done statically during initialization time. The netdev->features is initialized based on the entries allocated at the low level. -> Removed ndo_features_check callback. -> Used eth_broadcast_addr, eth_zero_addr where ever applicable. -> Use -EOPNOTSUPP instead of -ENOTSUPP.

2020-10-26octeontx2-pf: Fix interface down flag on errorGeetha sowjanya
commit 11b46e80102666f8a57f55571640ab392abc33cc from git@git.assembla.com:cavium/WindRiver.linux.git In the existing code while changing the number of TX/RX queues using ethtool the PF/VF interface resources are freed and reallocated (otx2_stop and otx2_open is called) if the device is in running state. If any resource allocation fails in otx2_open, driver free already allocated resources and return. But again, when the number of queues changes as the device state still running oxt2_stop is called. In which we try to free already freed resources leading to driver crash. This patch fixes the issue by setting the INTF_DOWN flag on error and free the resources in otx2_stop only if the flag is not set.

2020-02-27octeontx2-pf: Remove multisegment RX_SG processing logicSunil Goutham
commit bd2d6642ce2aef47308ebb8544d744adca12402e from git@git.assembla.com:cavium/WindRiver.linux.git Since now there will always be only one segment in CQE_RX, cleaned up NAPI handlers etc to get rid of unnecessary multisegment handling logic. Also added structs for full CQE_RX and CQE_TX to avoid junk subdescriptor accessing logic. Other changes done - It's been observed that ocassionally HW is doing a partial CQE write (16byte) due to which cqe_hdr->cqe_type is valid but rest of the descriptor is stale. This is resulting in buffer double free issues. Hence along with cqe_type check sg->subdc also to determine if a CQE is valid or not. No changes needed for CQE_TX as full CQE_TX is within 16 bytes. - Adjusted RQ's Aura backpressure level for better performance with higher queue counts (> 12). There still a 10% gap between flowcontrol enable and disable for 24queues. Upto 12queues it is negligible. - Removed lockless transmit capability which at times resulting in wrong accounting of BQL limits.

commit b1b525868f846e2599dd96ac881d8e483d162c0d from git@git.assembla.com:cavium/WindRiver.linux.git The stats are put in the shared data struct fwdata. A PHY driver indicates that it has FEC stats by setting the flag fwdata.phy.misc.has_fec_stats (for now, only the LIO3 card's 6141 PHY does this; all other PHYs clear that flag). On LIO3, FEC can be enabled at the PHY line-side only, never at the PHY host-side. So for LIO3, the ethtool FEC stats come from the PHY (not from CGX). Besides CGX_CMD_GET_PHY_FEC_STATS, also add CGX_CMD_PRBS and CGX_CMD_DISPLAY_EYE to enum cgx_cmd_id so that Linux's enum list is in sync with ATF's enum list.
