Subject: [PATCH 88/89] Fix "net" command on kernel configured with
|
||
|
|
CONFIG_IPV6=m
|
||
|
|
|
||
|
|
On a kernel configured with CONFIG_IPV6=m, struct inet6_ifaddr is not
|
||
|
|
defined in kernel. Without the patch, the "net" command fails with the
|
||
|
|
following error.
|
||
|
|
|
||
|
|
net: invalid structure member offset: inet6_ifaddr_if_next
|
||
|
|
FILE: net.c LINE: 1017 FUNCTION: get_device_ip6_address()
