Description

The set_error_count_limit function is commented out everywhere it is called so it is not clear what error count limit is being used and it does not seem like that can be overridden on the command line like it should be able to.

Per PCIe spec (Gen 5, revision 1, section 4.2.13.2, page 402), if there is no limit set, the default value is 4

Research direction

Start by tracing the commented-out set_error_count_limit call sites and the command-line option handling. Check how the current error-count limit is selected, compare the no-limit behavior with the PCIe Gen 5 specification's default of 4, and verify that a command-line override is honored. Done means the limit has a defined default and can be overridden as intended.
