Change for the worse in rsu wireless driver

from Idwer Vollering <vidwer_at_gmail.com>:

I have a patch for that:

                break;
        case R92S_EVT_FWDBG:
-               if (ifp->if_flags & IFF_DEBUG) {
+               if (rsu_debug >= 6) {
                        buf[60] = '\0';
                        printf("FWDBG: %s\n", (char *)buf);
                }

(end of quote)

I do not put "> " in front of these lines for quoting here.

Patch failed to apply, something was malformed.

I have no directory named head, but even removing that left errors.

I suppose I could look through original file and patch, and manually make the changes with vi.  Should I try that?  I am already long overdue for bed.

Anyway, I have other stuff to do on computer, including NetBSD-current amd64 and i386 installations on USB sticks, plan to install on new hard drive as well.

I'll be more inclined to come back when cups 1.7.3 becomes available in ports tree.  I need to be able to print.  Maybe NetBSD will be mainly a way station for cross-compiling Linux?

Now FreeBSD 11-current amd64 betrays me again as I lost the wireless connection and have to boot into my FreeBSD 10-stable amd64 or i386 installation or NetBSD-head amd64.
