The patch looks good, but it could be improved to make life easier
for the users.
This is an error, why not print it at NOTICE level since DEBUG messages
are usually suppressed.
Please don't break long lines in log messages. The latter part of the message
is obvious, why not skip it.
Also since max_qp_wr is __u32, the print format should be %u
Instead:
DRV_LOG(NOTICE,
"port %u Tx WQEBB count (%u) exceeds the limit (%u)",
dev->data->port_id,
txq_calc_wqebb_cnt(tmpl),
priv->sh->device_attr.orig_attr.max_qp_wr);
Also, should it have a Fixes: tag to backport to stable?
