Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Support for IPv6 Identifier Locator Addressing (ILA).

ILA is a mechanism to do network virtualization without

encapsulation. The basic concept of ILA is that we split an

|
IPv6 address into a 64 bit locator and 64 bit identifier. The
|
|
identifier is the identity of an entity in communication
|
|
("who") and the locator expresses the location of the

|
entity ("where").
|
|
|

ILA can be configured using the "encap ila" option with

"ip -6 route" command. ILA is described in

mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly

deploy IPv6 unicast service to IPv4 sites to which it provides

customer premise equipment. Like 6to4, it utilizes stateless IPv6 in

IPv4 encapsulation in order to transit IPv4-only network

infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6

prefix of its own in place of the fixed 6to4 prefix.
