Functions which can't access MFRL (Management Firmware Reset Level)
register, have no use of fw_reset structures or events. Remove fw_reset
structures allocation and registration for fw reset events notifications
for these functions.

Having the devlink param enable_remote_dev_reset on functions that don't
have this capability is misleading as these functions are not allowed to
influence the reset flow. Hence, this patch removes this parameter for
such functions.

In addition, return not supported on devlink reload action fw_activate
for these functions.

Pull rdma fixes from Jason Gunthorpe:
 "Mostly irdma and bnxt_re fixes:

   - Missing error unwind in hf1

   - For bnxt - fix fenching behavior to work on new chips, fail
     unsupported SRQ resize back to userspace, propogate SRQ FW failure
     back to userspace.

   - Correctly fail unsupported SRQ resize back to userspace in bnxt

   - Adjust a memcpy in mlx5 to not overflow a struct field.

   - Prevent userspace from triggering mlx5 fw syndrome logging from
     sysfs

   - Use the correct access mode for MLX5_IB_METHOD_DEVX_OBJ_MODIFY to
     avoid a userspace failure on modify

   - For irdma - Don't UAF a concurrent tasklet during destroy, prevent
     userspace from issuing invalid QP attrs, fix a possible CQ
     overflow, capture a missing HW async error event

   - sendmsg() triggerable memory access crash in hfi1

   - Fix the srpt_service_guid parameter to not crash due to missing
     function pointer

   - Don't leak objects in error unwind in qedr

   - Don't weirdly cast function pointers in srpt"

net/mlx5e: Use the correct lag ports number when creating TISes 2024-01-24T08:15:32+00:00 Saeed Mahameed saeedm@nvidia.com 2023-12-16T03:31:14+00:00 25461ce8b3d28528f2c55f5e737e99d2906eda83 The cited commit moved the code of mlx5e_create_tises() and changed the loop to create TISes over MLX5_MAX_PORTS constant value, instead of getting the correct lag ports supported by the device, which can cause FW errors on devices with less than MLX5_MAX_PORTS ports. Change that back to mlx5e_get_num_lag_ports(mdev). Also IPoIB interfaces create there own TISes, they don't use the eth TISes, pass a flag to indicate that.
