bnxt_en: Fix VLAN acceleration handling in bnxt_fix_features().

2020-04-27T18:44:05Z

The current logic in bnxt_fix_features() will inadvertently turn on both CTAG and STAG VLAN offload if the user tries to disable both. Fix it by checking that the user is trying to enable CTAG or STAG before enabling both. The logic is supposed to enable or disable both CTAG and STAG together.

bnxt_en: Return error when allocating zero size context memory.

2020-04-27T18:44:05Z

bnxt_alloc_ctx_pg_tbls() should return error when the memory size of the context memory to set up is zero. By returning success (0), the caller may proceed normally and may crash later when it tries to set up the memory. Fixes: 08fe9d181606 ("bnxt_en: Add Level 2 context memory paging support.")

bnxt_en: Improve AER slot reset.

2020-04-27T18:44:05Z

Improve the slot reset sequence by disabling the device to prevent bad DMAs if slot reset fails. Return the proper result instead of always PCI_ERS_RESULT_RECOVERED to the caller. Fixes: 6316ea6db93d ("bnxt_en: Enable AER support.") Signed-off-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: Reduce BNXT_MSIX_VEC_MAX value to supported CQs per PF.

2020-04-27T18:44:05Z

Broadcom adapters support only maximum of 512 CQs per PF. If user sets MSIx vectors more than supported CQs, firmware is setting incorrect value for msix_vec_per_pf_max parameter. Fix it by reducing the BNXT_MSIX_VEC_MAX value to 512, even though the maximum # of MSIx vectors supported by adapter are 1280. Fixes: f399e8497826 ("bnxt_en: Use msix_vec_per_pf_max and msix_vec_per_pf_min devlink params.") Signed-off-by: Vasundhara Volam Signed-off-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: Fix VF anti-spoof filter setup.

2020-04-27T18:44:05Z

Fix the logic that sets the enable/disable flag for the source MAC filter according to firmware spec 1.7.1. In the original firmware spec. before 1.7.1, the VF spoof check flags were not latched after making the HWRM_FUNC_CFG call, so there was a need to keep the func_flags so that subsequent calls would perserve the VF spoof check setting. A change was made in the 1.7.1 spec so that the flags became latched. So we now set or clear the anti- spoof setting directly without retrieving the old settings in the stored vf->func_flags which are no longer valid. We also remove the unneeded vf->func_flags.

net: systemport: suppress warnings on failed Rx SKB allocations

2020-04-24T23:50:01Z

The driver is designed to drop Rx packets and reclaim the buffers when an allocation fails, and the network interface needs to safely handle this packet loss. Therefore, an allocation failure of Rx SKBs is relatively benign. However, the output of the warning message occurs with a high scheduling priority that can cause excessive jitter/latency for other high priority processing. This commit suppresses the warning messages to prevent scheduling problems while retaining the failure count in the statistics of the network interface.

net: bcmgenet: correct per TX/RX ring statistics

2020-04-23T23:02:05Z

The change to track net_device_stats per ring to better support SMP missed updating the rx_dropped member. The ndo_get_stats method is also needed to combine the results for ethtool statistics (-S) before filling in the ethtool structure.

net: broadcom: convert to devm_platform_ioremap_resource_byname()

2020-04-21T22:53:54Z

Use the function devm_platform_ioremap_resource_byname() to simplify source code which calls the functions platform_get_resource_byname() and devm_ioremap_resource(). Remove also a few error messages which became unnecessary with this software refactoring. Suggested-by: Markus Elfring Signed-off-by: Dejin Zheng Signed-off-by: David S. Miller

net: systemport: Omit superfluous error message in bcm_sysport_probe()

In the function bcm_sysport_probe(), when get irq failed, the function platform_get_irq() logs an error message, so remove redundant message here. Signed-off-by: Tang Bin Acked-by: Florian Fainelli Signed-off-by: David S. Miller
