net: mv643xx_eth: disable napi when init rxq or txq failed in mv643xx_eth_open()

2022-11-10T12:30:01Z

When failed to init rxq or txq in mv643xx_eth_open() for opening device, napi isn't disabled. When open mv643xx_eth device next time, it will trigger a BUG_ON() in napi_enable(). Compile tested only.

octeontx2-pf: Fix SQE threshold checking

2022-11-08T12:43:46Z

Current way of checking available SQE count which is based on HW updated SQB count could result in driver submitting an SQE even before CQE for the previously transmitted SQE at the same index is processed in NAPI resulting losing SKB pointers, hence a leak. Fix this by checking a consumer index which is updated once CQE is processed.

octeontx2-pf: NIX TX overwrites SQ_CTX_HW_S[SQ_INT]

2022-11-04T10:55:05Z

In scenarios where multiple errors have occurred for a SQ before SW starts handling error interrupt, SQ_CTX[OP_INT] may get overwritten leading to NIX_LF_SQ_OP_INT returning incorrect value. To workaround this read LMT, MNQ and SQ individual error status registers to determine the cause of error.

Fix build errors when MACSEC=m and OCTEONTX2_PF=y by having OCTEONTX2_PF depend on MACSEC if it is enabled. By adding "|| !MACSEC", this means that MACSEC is not required -- it can be disabled for this driver. drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.o: in function `otx2_remove': ../drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.c:(.text+0x2fd0): undefined reference to `cn10k_mcs_free' mips64-linux-ld: drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.o: in function `otx2_mbox_up_handler_mcs_intr_notify': ../drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.c:(.text+0x4610): undefined reference to `cn10k_handle_mcs_event' Reported-by: kernel test robot Fixes: c54ffc73601c ("octeontx2-pf: mcs: Introduce MACSEC hardware offloading") Signed-off-by: Randy Dunlap Cc: Subbaraya Sundeep Cc: Sunil Goutham Cc: Geetha sowjanya Cc: hariprasad Cc: "David S.
