stable inclusion from stable-v5.10.184 commit 84dbd27ad5dace21830c67d01470e9121a044b22 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8L4MY

--------------------------------

[ Upstream commit 1d997801c7cc6a7f542e46d5a6bf16f893ad3fe9 ]

Only older NIC controller's firmware uses the PROC AP reset type. Firmware on 5731X/5741X and newer chips does not support this reset type. When bnxt_reset() issues a series of resets, this PROC AP reset may actually fail on these newer chips because the firmware is not ready to accept this unsupported command yet. Avoid this unnecessary error by skipping this reset type on chips that don't support it.
