OK. That makes more sense - it wasn't clear to me how it could be
correct to proceed if the links were down but now I understand how that
works. I think that explanation should go in the commit message.
>>> if (!wait_port_online(fc_regs, FC_PORT_STATUS_RETRY_INTERVAL_US,
>>> FC_PORT_STATUS_RETRY_CNT)) {
>>> pr_debug("%s: wait on port %d to go online timed out\n",
>>> __func__, port);
As an aside, should this be a bit noisier? It seems like something
a user would probably want to know - especially in the case where
something has actually gone wrong so there's no link state change
interrupt forthcoming regardless of how long you wait.
