Subject: add anaconda-style option parsing to ip_to_var
X-Git-Tag: 019~26
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f629355b2fbd0ec99960609212e2b34e62c55d84;p=platform%2Fupstream%2Fdracut.git

add anaconda-style option parsing to ip_to_var

Anaconda used arguments of the form:

  ip=<ip> gateway=<gw> netmask=<nm>

for static IP configuration. So if we get a value for "ip" that's an IP
address, look for gateway= and netmask= and related args to fill in the
ip config vars.
