bnxt: revert hastily merged uAPI aberrations This reverts: commit 02acd399533e ("bnxt_en: parse result field when NVRAM package install fails") commit 22f5dba5065d ("bnxt_en: add an nvm test for hw diagnose") commit bafed3f231f7 ("bnxt_en: implement hw health reporter") These patches are still under discussion / I don't think they are right, and since the authors don't reply promptly let me lessen my load of "things I need to resolve before next release" and revert them.

bnxt_en: add enable_remote_dev_reset devlink parameter The reported parameter value should not take into account the state of remote drivers. Firmware will reject remote resets as appropriate, thus it is not strictly necessary to check HOT_RESET_ALLOWED before attempting to initiate a reset. But we add the check so that we can provide more intuitive messages when reset is not permitted. This firmware setting needs to be restored from all functions after a firmware reset.

The failure in SW means memory issues, wrong parameters, programmer error e.t.c.

bnxt_en: fix read of stored FW_PSID version on P5 devices P5 devices store NVM arrays using a different internal representation.

If user sets MSIx vectors more than supported CQs, firmware is setting incorrect value for msix_vec_per_pf_max parameter.

The current code creates the reporters unconditionally as long as bp->fw_health is valid, and that's not correct.
