Bitbake would use wget with "--no-passive" to fetch the source.
Behind most firewall and NAT
configurations it could work well.However, in some rare firewall
configurations,
active FTP actually works when passive FTP doesn't.

So disable the use of the passive FTP transfer mode for wget.

As you say, its much more likely that passive ftp would work than
active ftp, so this change would make things worse for more people?

We're trying to get away from having ftp urls in oe-core at all so
hopefully this isn't a big deal.

    <p>Thanks for your reminding, I could  try to use https url instead
      of ftp url in alsa-lib_1.1.6.bb.  The alsa also provides the HTTP
      server for downing the packages.
