treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("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/'

bridge: Add vlan filtering infrastructure

2013-02-14T00:41:46+00:00

Adds an optional infrustructure component to bridge that would allow
native vlan filtering in the bridge.  Each bridge port (as well
as the bridge device) now get a VLAN bitmap.  Each bit in the bitmap
is associated with a vlan id.  This way if the bit corresponding to
the vid is set in the bitmap that the packet with vid is allowed to
enter and exit the port.

Write access the bitmap is protected by RTNL and read access
protected by RCU.

Vlan functionality is disabled by default.

net: bridge builtin vs. ipv6 modular

2011-03-10T21:45:57+00:00

When configs BRIDGE=y and IPV6=m, this build error occurs:

br_multicast.c:(.text+0xa3341): undefined reference to `ipv6_dev_get_saddr'

BRIDGE_IGMP_SNOOPING is boolean; if it were tristate, then adding
	depends on IPV6 || IPV6=n
to BRIDGE_IGMP_SNOOPING would be a good fix.  As it is currently,
making BRIDGE depend on the IPV6 config works.

bridge: depends on INET

2010-03-03T09:23:22+00:00

br_multicast calls ip_send_check(), so it should depend on INET.

built-in:
br_multicast.c:(.text+0x88cf4): undefined reference to `ip_send_check'

or modular:

bridge: Add core IGMP snooping support

2010-02-28T08:48:45+00:00

This patch adds the core functionality of IGMP snooping support
without actually hooking it up.  So this patch should be a no-op
as far as the bridge's external behaviour is concerned.

All the new code and data is controlled by the Kconfig option
BRIDGE_IGMP_SNOOPING.  A run-time toggle is also available.

The multicast switching is done using an hash table that is
lockless on the read-side through RCU.  On the write-side the
new multicast_lock is used for all operations.  The hash table
supports dynamic growth/rehashing.

The hash table will be rehashed if any chain length exceeds a
preset limit.  If rehashing does not reduce the maximum chain
length then snooping will be disabled.

These features may be added in future (in no particular order):

* IGMPv3 source support
* Non-querier router detection
* IPv6
