2020-04-17scsi: qedf: Fix crash when MFW calls for protocol stats while function is ↵Chad Dupuis
still probing The MFW may make a call to qed and then to qedf for protocol statistics while the function is still probing. If this happens it's possible that some members of the struct qedf_ctx may not be fully initialized which can result in a NULL pointer dereference or general protection fault. To prevent this, add a new flag call QEDF_PROBING and set it when the __qedf_probe() function is active. Then in the qedf_get_protocol_tlv_data() function we can check if the function is still probing and return immediantely before any uninitialized structures can be touched.

2020-04-17scsi: qedf: Keep track of num of pending flogiSaurav Kashyap
If a port is brought down for an extended period of time, the fipvlan counter gets exhausted and the driver will fall back to default VLAN 1002 and call fcoe_ctlr_link_up to log in. However, the switch will discard the FLOGI attempt because the VLAN is now different. Keep track of the number of FLOGI attempts and if a threshold of QEDF_FLOGI_RETRY_CNT is exceeded, perform a context soft reset.

2020-03-05scsi: qedf: Use pci_get_dsn()Jacob Keller
Replace the open-coded implementation for reading the PCIe DSN with pci_get_dsn(). The original code used a for-loop that looped over each of the 8 bytes and copied them into a temporary buffer. pci_get_dsn() uses two calls to pci_read_config_dword, and correctly bitwise ORs them into a u64.

2019-02-19scsi: fcoe: make use of fip_mode enum completeSedat Dilek
commit 1917d42d14b7 ("fcoe: use enum for fip_mode") introduces a separate enum for the fip_mode that shall be used during initialisation handling until it is passed to fcoe_ctrl_link_up to set the initial fip_state. That change was incomplete and gcc quietly converted in various places between the fip_mode and the fip_state enum values with implicit enum conversions, which fortunately cannot cause any issues in the actual code's execution. clang however warns about these implicit enum conversions in the scsi drivers. This commit consolidates the use of the two enums, guided by clang's enum-conversion warnings. This commit now completes the use of the fip_mode: It expects and uses fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up(). It also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to indicate these two enums are distinct.
