[dpdk-dev] [PATCH] cmdline: Fix broken functionality in FreeBSD

[dpdk-dev] [PATCH] cmdline: Fix broken functionality in FreeBSD

[Sergio Gonzalez Monroy]

Some features of the cmdline were broken in FreeBSD as a result of
termios not being compiled.

Not sure I understand the changelog above.  You're removing ifdefs below which
makes sense, but are you now assuming that BSD will be built with termios
support, or do you need to add some alternate dependency check during the
configuration of DPDK?

Yes, I was assuming that BSD has termios support.
Is it not a fair assumption?

No, I think its a perfectly fair assumption.  I was just trying to understand
the history of the ifdefs there.  Sounds like it was a dumb idea to intiially
ifdef the termios stuff out way back when.

The ifdef probably dates from when there were just two versions of DPDK: linux
and baremetal. Guess which one didn't have the termios support :-)
