Please re-read what I said -- you broke error handling and potentially
resume. Previously, the firmware was available without a sleeping call
to user space to get it. Now, it is not. You cannot sleep in
typhoon_tx_timeout(), and trying to get a firmware image in resume is
going to be a problem if your file system is NFS mounted over the NIC
you're trying to resume.
