Initial Package Version: 4.2.2
|
|
Upstream Status: unknown
|
|
Origin: found at fedora
|
|
Description: Allow dhcp4 to work even if the kernel doesn't support ipv6.
|
|
Fixed up by hand to apply to 4.2.2 (to me, it looks identical to the 4.2.0
|
|
version, but patch failed in one hunk when I tried to apply that one).
