Subject: net: Don't write the "serverip" env var if configured not to
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=a3e1a727fe8a8b0294fe3ffbc8dcd2f14a4e5a4e;p=u-boot.git

net: Don't write the "serverip" env var if configured not to

Before this patch, bootp would not overwrite the value, but the
value was still clobbered in the env
