I am afraid that I don't know enough about the solos hardware to know
if it needs to be rewritten.  I gather the solos returns at least three
kinds of packets, data, status and command.  If you wish to eliminate
the FIXME comment, you could just write:

@@ -850,8 +850,7 @@ static void solos_bh(unsigned long card_arg)
                                dev_kfree_skb_any(skb);
                                break;
 
-                       case PKT_COMMAND:
-                       default: /* FIXME: Not really, surely? */
+                       default: /* PKT_COMMAND */
                                if (process_command(card, port, skb))
                                        break;
                                spin_lock(&card->cli_queue_lock);

and be done with it since that will preserve existing behavior.
