I'm not completely against this change, but that scary comment is there
on purpose and it is not fully obsolete. It is still possible to get
HFA3841 cards into state which require hardware modifications to recover
from (i.e., they are as good as dead for most users). Taken into this
account, I would prefer that the help text for HOSTAP_FIRMWARE_NVRAM
would include a warning about the potential issues of using incorrect
firmware images. In most cases, RAM (volatile) download can be used to
upgrade the firmware without having to modify the flash contents. This
is also what the current Windows drivers are doing.
