| 2020-03-01 | bnxt_en: reinitialize IRQs when MTU is modified | Vasundhara Volam | |
| MTU changes may affect the number of IRQs so we must call bnxt_close_nic()/bnxt_open_nic() with the irq_re_init parameter set to true. The reason is that a larger MTU may require aggregation rings not needed with smaller MTU. We may not be able to allocate the required number of aggregation rings and so we reduce the number of channels which will change the number of IRQs. Without this patch, it may crash eventually in pci_disable_msix() when the IRQs are not properly unwound. Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")

| 2020-02-20 | bnxt_en: Improve device shutdown method. | Vasundhara Volam | |

| 2020-02-03 | bnxt_en: Fix TC queue mapping. | Michael Chan | |
| The driver currently only calls netdev_set_tc_queue when the number of TCs is greater than 1. Instead, the comparison should be greater than or equal to 1. Even with 1 TC, we need to set the queue mapping. This bug can cause warnings when the number of TCs is changed back to 1. Fixes: 7809592d3e2e ("bnxt_en: Enable MSIX early in bnxt_init_one().")

| 2020-02-03 | bnxt_en: Fix logic that disables Bus Master during firmware reset. | Vasundhara Volam | |
| The current logic that calls pci_disable_device() in __bnxt_close_nic() during firmware reset is flawed. If firmware is still alive, we're disabling the device too early, causing some firmware commands to not reach the firmware. Fix it by moving the logic to bnxt_reset_close(). If firmware is in fatal condition, we call pci_disable_device() before we free any of the rings to prevent DMA corruption of the freed rings. If firmware is still alive, we call pci_disable_device() after the last firmware message has been sent. Fixes: 3bc7d4a352ef ("bnxt_en: Add BNXT_STATE_IN_FW_RESET state.")

| 2020-02-03 | bnxt_en: Fix RDMA driver failure with SRIOV after firmware reset. | Michael Chan | |
| bnxt_ulp_start() needs to be called before SRIOV is re-enabled after firmware reset. Re-enabling SRIOV may consume all the resources and may cause the RDMA driver to fail to get MSIX and other resources. Fix it by calling bnxt_ulp_start() first before calling bnxt_reenable_sriov(). We re-arrange the logic so that we call bnxt_ulp_start() and bnxt_reenable_sriov() in proper sequence in bnxt_fw_reset_task() and bnxt_open(). The former is the normal coordinated firmware reset sequence and the latter is firmware reset while the function is down. This new logic is now more straight forward and will now fix both scenarios.

Also call devlink_port_type_eth_set() after registering netdev as devlink port updates the netdev structure and notifies user.

| In bnxt_update_phy_setting(), ethtool_get_link_ksettings() and bnxt_disable_an_for_lpbk(), we inconsistently use netif_carrier_ok() to determine link. Instead, we should use bp->link_info.link_up which has the true link state. The netif_carrier state may be off during self-test and while the device is being reset and may not always reflect the true link state. By always using bp->link_info.link_up, the code is now more consistent and more correct. Some unnecessary link toggles are now prevented with this patch.

| 2019-12-10 | bnxt_en: Add missing devlink health reporters for VFs. | Vasundhara Volam | |
| The VF driver also needs to create the health reporters since VFs are also involved in firmware reset and recovery. Modify bnxt_dl_register() and bnxt_dl_unregister() so that they can be called by the VFs to register/unregister devlink. Only the PF will register the devlink parameters. With devlink registered, we can now create the health reporters on the VFs.

| Fix the logic to properly check the fw capabilities and create the devlink health reporters only when needed. The current code creates the reporters unconditionally as long as bp->fw_health is valid, and that's not correct. Call bnxt_dl_fw_reporters_create() directly from the init and reset code path instead of from bnxt_dl_register(). This allows the reporters to be adjusted when capabilities change. The same applies to bnxt_dl_fw_reporters_destroy().

| bp->fw_health needs to be allocated for either the firmware initiated reset feature or the driver initiated error recovery feature. The current code is not allocating bp->fw_health for all the necessary cases. This patch corrects the logic to allocate bp->fw_health correctly when needed. If allocation fails, we clear the feature flags. We also add the the missing kfree(bp->fw_health) when the driver is unloaded. If we get an async reset message from the firmware, we also need to make sure that we have a valid bp->fw_health before proceeding.

Lee, Andre Guedes, Anders Roxell, Mao Wenan, Yue Haibing. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> | |||
| 2019-11-18 | bnxt_en: Abort waiting for firmware response if there is no heartbeat. | Pavan Chebbi | |
| This is especially beneficial during the NVRAM related firmware commands that have longer timeouts. If the BNXT_STATE_FW_FATAL_COND flag gets set while waiting for firmware response, abort and return error.

| 2019-11-18 | bnxt_en: Set MASTER flag during driver registration. | Vasundhara Volam | |
| The Linux driver is capable of being the master function to handle resets, so we set the flag to let firmware know. Some other drivers, such as DPDK, is not capable and will not set the flag.

| 2019-11-18 | bnxt_en: Extend ETHTOOL_RESET to hot reset driver. | Vasundhara Volam | |
| If firmware supports hot reset, extend ETHTOOL_RESET to support hot reset driver which does not require a driver reload after ETHTOOL_RESET. The driver will go through the same coordinated reset sequence as a firmware initiated fatal/non-fatal reset.

| 2019-11-18 | bnxt_en: Improve RX buffer error handling. | Michael Chan | |
| When hardware reports RX buffer errors, the latest 57500 chips do not require reset. The packet is discarded by the hardware and the ring will continue to operate. Also, add an rx_buf_errors counter for this type of error. It can help the user to identify if the aggregation ring is too small.

| 2019-11-18 | bpf: Convert bpf_prog refcnt to atomic64_t | Andrii Nakryiko | |
| Similarly to bpf_map's refcnt/usercnt, convert bpf_prog's refcnt to atomic64 and remove artificial 32k limit. This allows to make bpf_prog's refcounting non-failing, simplifying logic of users of bpf_prog_add/bpf_prog_inc. Validated compilation by running allyesconfig kernel build.

| 2019-11-02 | Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net | David S. Miller | |
| The only slightly tricky merge conflict was the netdevsim because the mutex locking fix overlapped a lot of driver reload reorganization. The rest were (relatively) trivial in nature. Signed-off-by: David S. Miller <davem@davemloft.net> | |||
