ng ucode. There was no
evaluation of the importance of the ucode at the time.

Based on comments in earlier versions of this driver, and in
the source code for the FreeBSD fxp driver, we can assume that
the ucode implements the "CPU Cycle Saver" feature on supported
adapters.  Although generally wanted, this is an optional
feature. The ucode source is not available, preventing it from
being included in free distributions. This creates unnecessary
problems for the end users. Doing a network install based on a
free distribution installer requires the user to download and
insert the ucode into the installer.

Making the ucode optional when possible improves the user
experience and driver usability.

The ucode for some adapters include a bugfix, making it
essential.  We continue to fail for these adapters unless the
ucode is available.
