net/bnxt: message timeout with optimization level 2

Hi,

We are testing BNXT PMD with a P2100G on FreeBSD and are having issues
depending on how we compile DPDK. We compile from sources. When using
optimization level g or 1, everything works. However, as soon as we use the
default optimization level or the level 2, we get errors and we cannot get
the PMD to load for this device.

We have tested 23.11 and 24.07 and see the same issues with both.

Looking into the debugger, not all messages fail. The first one to fail is
the one for the backing store cfg.

Here are the logs we get with optimization level 2:

ERROR: bnxt_hwrm_send_message(): Error(timeout) sending msg 0x0193, seq_id 8
ERROR: bnxt_hwrm_func_backing_store_cfg(): failed rc:-60
ERROR: bnxt_alloc_ctx_mem(): Failed to configure context mem: rc = -60
ERROR: ETHDEV: ethdev initialisation failed
ERROR: PCI_BUS: Requested device 0000:c1:00.0 cannot be used

We are using firmware 231.0.162.1

Does that ring a bell?

Thanks

Baptiste Wicht
