net/mlx5e: Support dump callback in TX reporter
Add support for SQ's FW dump on TX reporter's events. Use Resource dump
API to retrieve the relevant data: SX slice, SQ dump and SQ buffer. Wrap
it in formatted messages and store the binary output in devlink core.
Example:
$ devlink health dump show pci/0000:00:0b.0 reporter tx
SX Slice:
